Best Vietnam eSIM Providers: Viettel, VinaPhone, MobiFone & Travel eSIMs Compared
Jun
The best eSIM Vietnam providers depends on your trip, not only on the brand name. A first-time tourist who mainly needs maps, Grab, translation, hotel messages, and social apps can usually use a data-only travel eSIM. A traveler who needs a Vietnamese phone number, local calls, or SMS should compare local SIM and eSIM options more carefully.
There is no single “best Vietnam eSIM provider” for everyone. Viettel, VinaPhone, and MobiFone are local Vietnamese mobile networks. Airalo, Saily, Holafly, Ubigi, Gigago, MobiMatter, and Twise are eSIM sellers, travel eSIM brands, resellers, or marketplaces that may connect through local networks.
If Vietnam is part of a wider Southeast Asia route, Twise Southeast Asia 5 Countries eSIM can be a practical regional option. It covers Vietnam, Thailand, Singapore, Malaysia, and Indonesia with daily high-speed data, unlimited 4G at 5Mbps after the daily allowance, and hotspot support.
This guide compares Vietnam eSIM providers by real traveler needs: data-only internet, local number, rural coverage, unlimited data, hotspot, regional travel, and setup before arrival.
Quick Verdict: Which eSIM Vietnam Providers Should You Choose?
For most first-time travelers, a data-only Vietnam eSIM is enough. It will support the apps you are most likely to use on arrival, including Grab, Google Maps, Apple Maps, Zalo, WhatsApp, hotel email, translation tools, and social media.
If you need Vietnamese calls, SMS, or a local number, choose more carefully. Many travel eSIMs are data-only, which means they can connect your phone to the internet but cannot make standard cellular calls or receive normal SMS.
| Traveler need | Best provider type | Why |
| First-time traveler who mainly needs data | Travel eSIM or Twise regional eSIM | It is easier to set up before arrival and usually enough for maps, Grab, messages, and translation. |
| City trip to Hanoi, Ho Chi Minh City, or Da Nang | Airalo, Saily, Ubigi, Holafly, Gigago, or Twise | Most data-first options can work well in major cities when the local network partner is strong. |
| Rural route such as Ha Giang, Sapa, or mountain areas | Viettel-based or strong local-network plan | Network choice matters more outside cities, especially on mountain roads or rural routes. |
| Need Vietnamese phone number | Local SIM/eSIM or local-number reseller | Many travel eSIMs are data-only and do not include a local Vietnamese number. |
| Heavy data or unlimited-style use | Holafly, Ubigi unlimited, or local high-data plans | Travelers should check hotspot, speed, and fair-use rules before relying on unlimited claims. |
| Laptop hotspot or remote work | Plan with clear hotspot and high-speed allowance | Laptop use can consume data quickly, so vague unlimited claims are risky. |
| Vietnam plus Thailand, Singapore, Malaysia, or Indonesia | Twise Southeast Asia 5 Countries eSIM | One regional eSIM can cover several nearby destinations without buying a new plan in each country. |
| Cheapest short trip | Fixed-data travel eSIM | A small fixed-data plan is usually enough for maps, messages, and light browsing. |
| Traveler arriving late | Pre-installed travel eSIM | It avoids airport counter dependency after a long flight or late-night arrival. |
Direct answer
Choose a data-only travel eSIM if you mainly need internet. Choose a local SIM or eSIM if you need a Vietnamese phone number, calls, or SMS. Choose a regional eSIM like Twise if Vietnam is one stop in a wider Southeast Asia trip.
How to Compare Vietnam eSIM Providers Without Getting Misled
Many Vietnam eSIM comparison pages rank providers by price or data size. That can be useful, but it often hides the real buying decision. You should compare the exact plan, not just the brand.
Provider is not always the same as network
The local network is the company that connects your phone inside Vietnam. The main local networks travelers often compare are Viettel, VinaPhone or VNPT, MobiFone, and Vietnamobile.
The seller or provider is the company you buy the eSIM from. This may be Airalo, Ubigi, Holafly, Saily, Gigago, Twise, or MobiMatter. A marketplace such as MobiMatter or eSIMDB may show plans from several different suppliers.
This distinction matters because the network affects signal and coverage, while the seller affects purchase flow, customer support, refund rules, setup instructions, and plan terms.
A travel eSIM may be sold by a global provider but connect through a local Vietnamese network. A reseller may offer several Vietnam eSIM plans using different local networks. This is why travelers should check the network listed on the exact plan page before buying.
Compare the exact plan, not only the brand
Before buying a Vietnam eSIM, check the local network, data amount, validity period, hotspot rules, top-up availability, and whether calls, SMS, or a local phone number are included. You should also confirm whether the plan is Vietnam-only or regional, whether it works on mobile phones only, when validity starts, what the refund policy says, and which support channel is available if activation fails.
A provider may have one Vietnam plan with a local number and another plan that is data-only. Do not assume the whole brand works one way.
Do not assume every Vietnam eSIM includes a phone number
Many Vietnam travel eSIM plans are data-only. A data-only eSIM is enough for Grab, maps, translation, hotel messages, Zalo, WhatsApp, iMessage, Messenger, FaceTime, and browsing.
It is not enough if you need standard cellular calls, normal SMS, or a Vietnamese phone number.
For example, Saily’s Vietnam eSIM page states that its plans are data-only and do not include traditional voice calls or SMS. Gigago’s Vietnam eSIM page shows that some Vietnam plans include a phone number while others do not.
Do not assume unlimited means full-speed unlimited
Unlimited data also needs careful reading. Some plans have no obvious total data cap. Some reduce speed after a daily allowance. Some allow phone data but limit hotspot. Some unlimited plans may be optimized for lighter use.
For remote work, laptop hotspot, and video calls, the speed and hotspot rules matter more than the word “unlimited.”
Vietnam eSIM Provider Types Explained
Different eSIM Vietnam providers solve different problems. A local carrier plan, a travel eSIM, a reseller plan, and a regional eSIM can all appear under “eSIM Vietnam,” but they are not the same product.
| Provider type | Examples | Best for | Watch out for |
| Local mobile network | Viettel, VinaPhone/VNPT, MobiFone | Local coverage and phone-number products | Passport registration, store setup, or airport kiosk steps may be required. |
| Travel eSIM brand | Airalo, Saily, Holafly, Ubigi, Nomad | Fast online setup and data-only travel | These plans usually do not include a local Vietnamese number. |
| Vietnam-focused reseller | Gigago and local travel SIM sellers | Network choice and some local-number plans | Plan terms can vary by selected product. |
| Marketplace | MobiMatter, eSIMDB | Price comparison across many plans | The underlying provider’s rules matter more than the marketplace name. |
| Regional eSIM | Twise SEA 5 Countries and Asia plans | Multi-country trips | Regional plans may not include a local number. |
| Local physical SIM | Viettel, VinaPhone, or MobiFone stores and kiosks | Calls, SMS, and local number use | Passport registration and queue time may be required. |
Where Twise fits
Twise Southeast Asia 5 Countries eSIM fits travelers who need Vietnam plus Indonesia, Malaysia, Singapore, or Thailand. It is a data-only regional eSIM. It supports hotspot and gives daily 1GB high-speed data, then unlimited 4G at 5Mbps until the daily reset after 00:00 AM GMT+8.
It does not include calls, texts, or a Vietnamese number.
Where local carriers fit
Choose Viettel, VinaPhone, or MobiFone directly if you need a Vietnamese number, calls, SMS, or local carrier registration. Local carrier products can be useful, but they may require passport registration, store setup, or in-country purchase steps.
Best Vietnam eSIM Providers Compared
Use this table to narrow your options. Then confirm the exact product page before buying because Vietnam eSIM providers can change networks, pricing, plan names, and policies.
| Provider | Best for | Network / provider angle | Phone number/SMS | Key caution |
| Twise Southeast Asia 5 Countries | Vietnam plus nearby Southeast Asia data use | Regional travel eSIM | No calls or SMS | It includes 1GB high-speed data per day, then 5Mbps. Top-up is not available. |
| Viettel | Local carrier and rural-focused routes | Vietnamese mobile network | Local SIM/eSIM may support number | Tourist SIM/eSIM registration may require passport steps. |
| VinaPhone / VNPT | Local carrier, city use, and national routes | Vietnamese mobile network | Local products may support number | Direct tourist eSIM purchase flow may be less simple online. |
| MobiFone | Local carrier alternatives and some reseller offers | Vietnamese mobile network | Local products may support number | Direct tourist purchase details can vary. |
| Airalo | App-based Vietnam data | Travel eSIM seller; check listed local network | Usually data-only | Check the exact network and plan before buying. |
| Saily | Beginner-friendly app data | Data-only travel eSIM | No traditional calls or SMS | It is not for local phone-number use. |
| Holafly | Unlimited-style phone data | Travel eSIM brand | Usually no local number | Check hotspot and fair-use rules. |
| Ubigi | Business/work data and top-up | Data plans with network varying by plan | Data-only | Unlimited-style plans may have optimized speeds. |
| Gigago | Local-number or network-choice shoppers | Vietnam-focused reseller | Some plans include number | Some plans do not, so the selected product matters. |
| MobiMatter | Price comparison | Marketplace | Depends on underlying eSIM | It is not one unified provider policy. |
| Pocket Wi-Fi | Group sharing | Rental device | No phone number by default | You need to carry, charge, and return the device. |
How to use this table
Start with your real need. If you only need maps, Grab, and messages, a data-only eSIM is usually enough. If you need local calls or SMS, look for a local-number SIM or eSIM. If rural route coverage is a priority, check the local network. If Vietnam is one stop in a wider Southeast Asia trip, compare regional eSIMs. If you need remote-work hotspot, read the hotspot and speed terms carefully.
Viettel eSIM Vietnam: Best for Local Carrier and Rural-Route Shoppers
Viettel is one of Vietnam’s major mobile networks and is often prioritized by travelers planning rural or mountainous routes.
What Viettel is good for
Viettel is worth comparing if your trip includes the Ha Giang Loop, Sapa, rural homestays, mountain roads, long bus rides, less touristy provinces, or situations where local carrier service matters more than the easiest online checkout.
Viettel can be a strong local carrier choice when coverage is the main priority. It may also be relevant if you want local SIM or eSIM features that a data-only travel eSIM does not provide.
Passport registration
Local Viettel tourist SIM or eSIM setup may require registration. Viettel’s tourist SIM flow asks users to upload passport photos and a portrait photo. Viettel tourist guidance also explains that travelers may need an original passport for official registration.
That does not make Viettel a bad choice. It simply means it is not as frictionless as a pre-trip data-only eSIM.
Who should choose Viettel
Viettel is a good fit if rural route coverage matters, if you want local carrier service, if you are comfortable with passport registration, or if you may need calls, SMS, or local number features. It is also worth considering if you can visit a kiosk, official store, or authorized point of sale after arrival.
Who may prefer a travel eSIM
Choose a travel eSIM if you mainly need data and want to prepare before arrival. For example, if you land late at Tan Son Nhat Airport and only need Grab, hotel messages, and maps, a pre-installed travel eSIM is usually easier than finding a SIM counter.
VinaPhone / VNPT eSIM Vietnam: Best for Data Plans and Travel eSIM Network Partners
VinaPhone / VNPT is another major Vietnamese mobile network. Many travelers may use VinaPhone indirectly through a travel eSIM provider.
What VinaPhone is good for
VinaPhone-based plans can be useful for standard tourist routes such as Hanoi, Ho Chi Minh City, Da Nang, Hoi An, Hue, Ninh Binh, Ha Long, and Phu Quoc.
Some travel eSIM providers list VinaPhone or VNPT as the local network partner on Vietnam plans. This means you may buy from an international eSIM provider but connect through VinaPhone or VNPT once you arrive.
Why VinaPhone matters for travel eSIMs
A traveler may buy from an international eSIM seller but connect to VinaPhone/VNPT in Vietnam. In that case, the buying experience comes from the travel eSIM company, but the local connection depends on VinaPhone/VNPT coverage and roaming arrangements.
This is why the network and the seller should be checked separately.
Who should consider VinaPhone-based options
A VinaPhone-based plan may fit travelers who want app-based setup, who see VinaPhone or VNPT clearly listed on the selected eSIM plan, and whose trip is city-heavy or focused on standard tourist routes. It is also a practical option if you do not need a Vietnamese phone number.
What to check
Before buying, confirm whether the plan supports hotspot, top-up, local number, calls, SMS, regional coverage, and pre-arrival activation. These details depend on the selected provider and plan.
MobiFone eSIM Vietnam: Best for Local Carrier Alternatives and Some Local-Number Offers
MobiFone is another local Vietnamese mobile network and an important alternative to Viettel and VinaPhone.
What MobiFone is good for
MobiFone can be useful if you want a local carrier alternative, especially in cities and standard tourist routes. MobiFone’s official eSIM page lists eSIM registration and activation guidance through stores or the My MobiFone app. It also refers to identity verification steps during activation.
MobiFone through resellers
Some reseller Vietnam eSIM products use MobiFone or MobiFone-style local plans. For example, Gigago’s Vietnam eSIM page shows different plan types and indicates that some local/MobiFone plans may include a phone number while other plans do not.
This is why it is important to read the selected plan, not only the provider name.
Who should consider MobiFone options
MobiFone may be worth considering if you want a local carrier alternative, if the reseller clearly states MobiFone network, if you want possible local number availability, and if your route is mainly urban or on standard tourist paths.
What to check
Before buying a MobiFone-based plan, check whether a phone number is included, whether SMS works, whether hotspot is allowed, whether registration is required, when activation starts, and whether the seller is MobiFone directly or a reseller.
Travel eSIM Providers for Vietnam: Airalo, Saily, Holafly, Ubigi, Gigago and MobiMatter
Travel eSIM providers are useful because you can usually buy online before departure and install by QR code or app. They are usually best for data convenience, not local phone-number needs.
Airalo
Airalo is best for app-based setup and simple travel data. Its Vietnam page shows Vietnam eSIM options, and travelers should check the current local network, data allowance, validity, and top-up availability on the selected plan.
Airalo is a good fit for first-time eSIM users who want a familiar global eSIM brand, fixed-data plans, app-based top-up, and no local number requirement.
The main caution is that Airalo is usually a data-first option. Travelers should check the exact network on the selected plan and decide whether they need a Vietnam-only plan or a regional Asia plan.
Saily
Saily is best for beginner-friendly app-led setup and data-only travel. Saily’s Vietnam eSIM page states that its Vietnam eSIM plans are data-only and do not include traditional voice calls or SMS.
Saily fits tourists who use WhatsApp, Telegram, Messenger, FaceTime, hotel email, and app-based communication. It also works for travelers who keep their home SIM active for calls and texts.
It is not suitable if you need a Vietnamese phone number, standard SMS, or local cellular calls. Rural performance also depends on the local network and the traveler’s exact location.
Holafly
Holafly is best for travelers who want unlimited-style phone data and do not want to count GB. Its Vietnam eSIM page advertises unlimited data, but travelers should check hotspot-sharing and fair-use rules before relying on it for laptop or family sharing.
Holafly fits heavy phone-data users, app-heavy tourists, and travelers who prefer not to manage fixed data amounts. It may be less suitable for laptop-heavy remote work if hotspot sharing is limited.
Ubigi
Ubigi is useful for travelers who want clear fixed-data packages, app balance checks, top-up, and a business-travel style account experience.
Ubigi’s Vietnam plan pages include fixed-data options such as 10GB for 30 days, and some plans describe QR-code delivery and activation before travel. Ubigi also lists an unlimited Vietnam option, but travelers should check the optimized speed before choosing it for remote work.
Ubigi is a good fit for travelers who want data more than phone-number service. It may not be the best fit if you need Vietnamese calls, SMS, or full-speed heavy hotspot.
Gigago
Gigago is useful for travelers who want Vietnam-specific options, possible network choice, and some local-number plans.
Gigago’s Vietnam eSIM page shows that some plans include a phone number while others do not. It also shows plans that vary by local network and data structure.
Gigago may fit travelers who want Vietnam-focused products, possible local-number options, and clearer local-network selection. The main caution is that not every Gigago plan has a phone number, so the exact product matters.
MobiMatter
MobiMatter is best for comparing many Vietnam eSIM options in one place. Because it is a marketplace, the underlying provider matters more than the MobiMatter name itself.
It can be useful for price comparison, flexible data amounts, and multi-country options. However, travelers should check the provider-specific support, hotspot rules, speed rules, refund terms, and whether the plan is data-only.
Twise Southeast Asia 5 Countries eSIM: Best for Vietnam Plus Nearby Countries
Twise Southeast Asia 5 Countries eSIM is not positioned as the best choice for every Vietnam traveler. It is strongest when Vietnam is part of a wider Southeast Asia trip and the traveler mainly needs mobile data.
What Twise offers
Twise Southeast Asia 5 Countries Travel eSIM covers Indonesia, Malaysia, Singapore, Thailand, and Vietnam.
It provides daily 1GB high-speed internet. After the daily high-speed allowance is used, data continues as unlimited 4G at 5Mbps until the end of the day. The daily high-speed allowance resets after 00:00 AM GMT+8. Hotspot is supported.
This model is easy to understand. You get high-speed data each day. After the daily high-speed allowance is used, the connection continues at 5Mbps instead of stopping completely.
What Twise does not include
Twise Southeast Asia 5 Countries eSIM is data-only. It does not include calls, texts, a Vietnamese phone number, or top-up. It is available for mobile devices only and is not recommended for tablets or other eSIM-compatible devices.
The QR activation validity is 90 days. The plan validity starts once the eSIM is activated. Each day ends at 11:59 PM GMT+8.
Who Twise fits best
Twise fits travelers who visit Vietnam plus Thailand, Singapore, Malaysia, or Indonesia and need mobile data more than calls or SMS. It is suitable for maps, Grab, translation, hotel messages, social apps, browser search, and light hotspot use.
For example, if your route is Singapore to Vietnam to Thailand, one regional eSIM can be easier than buying three separate country plans.
When Twise is not the best fit
Twise is not the best fit if you need a Vietnamese phone number, local calls, SMS, local SIM registration, top-up, full-speed unlimited data all day, tablet usage, or router usage.
If your Vietnam trip includes nearby Southeast Asia countries, compare Twise Southeast Asia 5 Countries eSIM before buying a Vietnam-only plan. It gives daily high-speed data, unlimited 4G at 5Mbps after the daily allowance, and hotspot support across Vietnam, Thailand, Singapore, Malaysia, and Indonesia.
You can also explore Twise eSIM options and check devices that work with eSIM before purchase.
Data-Only vs Vietnamese Phone Number: Which Provider Type Fits You?
This is one of the most important decisions when choosing Vietnam eSIM providers. Many first-time travelers only need data. Some travelers need a phone number.
| Need | Data-only travel eSIM | Local number SIM/eSIM |
| Maps | Yes | Yes |
| Grab app data | Yes | Yes |
| Hotel email/messages | Yes | Yes |
| WhatsApp/Zalo/Messenger | Yes | Yes |
| Standard local calls | No | Yes |
| SMS verification | No | Usually yes, if included |
| Delivery or local account setup | Maybe | More likely |
| Vietnamese number | No | Yes |
| Passport registration | Usually no | Often required |
When data-only is enough
Data-only is enough if you mainly use Grab in-app messaging, WhatsApp, Zalo, hotel email, Google Maps, Apple Maps, translation apps, mobile tickets, social apps, and browser search.
For many first-time tourists, this covers the real travel tasks they need after landing.
When you need a Vietnamese phone number
A Vietnamese number may be useful if you need local calls, SMS verification, delivery services, tour operator calls, local account setup, or contact with drivers outside app chat.
If these are important, compare local SIM/eSIM or Vietnam eSIM with phone number options instead of buying a standard data-only travel eSIM.
Passport and registration friction
Local SIM and eSIM products can require identity registration. For Viettel tourist SIM/eSIM, official sources show passport and photo steps. This is normal for local telecom service, but it adds setup friction compared with a travel data eSIM.
If you arrive late, travel with kids, or need Grab immediately, a pre-installed data eSIM can make the first hour easier.
Vietnam Coverage by Route: Cities, Islands, Mountains and Bus Routes
Coverage should be judged by route, not only by provider ranking. A plan that works well in Ho Chi Minh City may behave differently in Ha Giang, Sapa, Phu Quoc, or on a sleeper bus.
Hanoi, Ho Chi Minh City and Da Nang
In major cities, many data-first travel eSIMs can work well if the local network partner is strong.
City travelers usually need data for Grab, maps, restaurant search, translation, messaging, and hotel check-in. Data-only is often enough, but travelers should still check the network partner, data allowance, hotspot rules, and support.
Hoi An, Hue, Ninh Binh and Ha Long
These standard tourist routes usually have mobile coverage, but signal can vary indoors, on transport, or around rural homestays. It is still useful to save your hotel address and offline maps before moving between towns.
Ha Giang Loop and Sapa
For mountainous routes, network choice matters more. Prioritize plans that clearly list a strong local network partner and keep offline maps downloaded.
If you are riding the Ha Giang Loop, data is useful for navigation and communication, but offline preparation is still important because signal can drop on mountain roads.
Phu Quoc and islands
Island coverage can be less predictable than city coverage. Save hotel details, ferry information, flight details, and offline maps before arrival.
Sleeper buses and trains
Mobile signal can drop on long routes. Download maps, tickets, and hotel addresses before departure, especially on routes such as Hanoi to Sapa, Ho Chi Minh City to Da Lat, or long intercity bus rides.
Unlimited Data, Fixed Data and Hotspot: What Travelers Should Compare
eSIM Vietnam providers use different data models. Do not choose only by the biggest number.
Fixed-data plans
Fixed-data plans give a set amount of data for a set number of days. They are good for light and moderate users who mainly need maps, Grab, messages, hotel email, light social media, translation, and browsing.
If you know your data habits, fixed-data plans can be cost-effective.
Unlimited-style plans
Unlimited-style plans are useful for heavy phone-data users. They can be a good fit if you do not want to track every GB, but you should always check fair-use policy, speed management, hotspot allowance, video streaming rules, and whether the plan is data-only.
Holafly is a common unlimited-style Vietnam option, but travelers should check its hotspot-sharing rules before using it for laptop or family sharing.
Daily high-speed + fallback
Twise uses a daily high-speed plus fallback model. You get 1GB high-speed data per day, then unlimited 4G at 5Mbps after the daily allowance. The daily allowance resets after 00:00 AM GMT+8.
This is useful for travelers who want the connection to continue after high-speed data is used. 5Mbps can still support maps, messages, Grab, browsing, and translation, though it may feel limited for HD video, large uploads, or remote work.
Hotspot and laptop use
Remote workers should check hotspot allowance, speed after the cap, upload needs, top-up availability, whether tethering is allowed, plan validity, and device restrictions.
A phone-first plan may not be enough for laptop-heavy work. Use Twise’s guides on how to calculate what you need and how to save mobile data and money if you are unsure how much data to buy.
Buy Vietnam eSIM Online vs Local SIM at Airport
Both options can work. The better choice depends on what you need after landing.
Buy online before travel if you mainly need data
An online eSIM is usually better if you arrive late, want data immediately, do not need local calls or SMS, want to avoid airport counters, are visiting multiple countries, and have an eSIM-compatible phone.
This is usually the simplest option for first-time tourists who mainly need data.
Buy local SIM if you need local phone features
A local SIM may be better if you need a Vietnamese number, calls, SMS, local in-person support, or longer-stay local service. It can also make sense if you are comfortable with passport registration and want a local carrier product.
Airport reality
Airport kiosks are convenient, but they can be busy after international arrivals. If your first step is Grab, hotel contact, or a late-night transfer, pre-arrival eSIM setup reduces dependency on airport Wi-Fi.
Before buying, confirm your phone is eSIM-compatible using devices that work with eSIM.
What To Do If Your Vietnam eSIM Does Not Work
Most eSIM issues come from settings, activation timing, or wrong plan assumptions.
Before deleting the eSIM
Do not delete the eSIM immediately. Some eSIM profiles cannot be reinstalled without provider support. If the eSIM does not connect, troubleshoot first.
Check the main settings
Make sure the eSIM line is turned on and selected for cellular data. If the provider requires data roaming, turn it on for the travel eSIM line. If the provider gives APN settings, enter them exactly. Restart the phone, toggle airplane mode once, and check whether the plan has started and whether the provider covers your location.
Use an offline recovery plan
Before leaving home, save your QR code, order number, provider help page, hotel address, airport transfer details, offline maps, and home SIM access for bank 2FA.
After activation, use how to check roaming data consumption to avoid surprises.
If a plan does not match the advertised terms, review the provider’s support and refund policy. Twise customers can check the Twise refund policy.
How to Choose the Best Vietnam eSIM Provider for Your Trip
The right provider depends on your route, your phone-number needs, and your data behavior.
Choose Twise Southeast Asia 5 Countries eSIM if your trip is regional
Choose Twise if you need Vietnam plus Thailand, Singapore, Malaysia, or Indonesia. It fits travelers who mainly need mobile data, want hotspot support, are comfortable with 1GB high-speed data per day, and want unlimited 4G at 5Mbps after the daily allowance.
It is not the right choice if you need calls, SMS, or a Vietnamese phone number.
Choose Viettel if local carrier service and rural routes matter
Choose Viettel if you want local carrier service, rural route confidence, possible local number or call/SMS features, and are comfortable with passport registration through official Viettel channels or authorized points.
Choose VinaPhone / VNPT if your selected plan clearly uses that network
Choose VinaPhone / VNPT if your selected travel eSIM clearly lists VinaPhone or VNPT as the partner network and your route is mostly city or standard tourist destinations.
Choose MobiFone if you want a local carrier alternative
Choose MobiFone if you want a local carrier alternative, a reseller clearly lists MobiFone network, or you want possible local-number options for an urban or standard tourist route.
Choose Airalo or Saily if you want app-based data-only setup
Airalo or Saily can fit travelers who want app-based data-only setup, do not need a Vietnamese phone number, prefer familiar global travel eSIM brands, and mostly need maps, Grab, translation, and messaging.
Choose Holafly if you want unlimited-style phone data
Holafly can fit travelers who want unlimited-style phone data and do not want to manage fixed data amounts. Check hotspot-sharing rules before relying on it for laptop or family sharing.
Choose Ubigi if you want fixed-data plans or top-up
Ubigi can fit travelers who want clear fixed-data plans, top-up, and a business-travel style account experience without local phone-number features.
Choose Gigago if you want Vietnam-focused plan options
Gigago may fit travelers who want Vietnam-focused products, possible local-number plans, or clearer local-network selection. Read the selected plan carefully because not every plan includes a phone number.
Choose local SIM if you need local telecom features
A local SIM is usually better if you need a Vietnamese number, calls, SMS, local support, longer-stay local service, or in-person carrier help.

For most first-time tourists, a data-only Vietnam eSIM is enough for maps, Grab, translation, hotel messages, and social apps. If you need Vietnamese calls, SMS, or a local number, compare local SIM/eSIM options carefully.
If your route includes Vietnam plus Thailand, Singapore, Malaysia, or Indonesia, Twise Southeast Asia 5 Countries eSIM is a transparent regional option. It gives 1GB high-speed data per day, unlimited 4G at 5Mbps after the daily allowance, and hotspot support.
Before choosing a provider, decide whether your priority is data-only internet, a Vietnamese phone number, rural-route coverage, hotspot, unlimited data, or regional Southeast Asia coverage. Once you know that, the right Vietnam eSIM provider becomes much easier to choose.
