eSIM or Pocket WiFi: A Complete Comparison for 2025

When planning your next trip, staying connected is a top priority. Two of the most popular options are eSIM or Pocket WiFi. Each has unique advantages, depending on your travel style, number of devices, and budget. Here’s a complete comparison to help you decide which solution fits best in 2025. So eSIM or pocket Wifi? – Let’s find out!

What Is an eSIM?

An eSIM (embedded SIM) is a digital SIM built into your smartphone or tablet. Instead of swapping physical SIM cards, you can simply scan a QR code to activate your plan. There’s no need for shipping, pick-up, or inserting anything into your device. Once set up, your device connects to the local network automatically—making it a fast, hardware-free way to get online abroad.

Best for: Solo travelers, frequent flyers, and anyone who wants seamless setup without carrying extra gadgets.

What Is a Pocket WiFi?

A Pocket WiFi is a small, portable device that creates a personal Wi-Fi hotspot for your other devices. You rent or purchase the device before your trip, carry it with you, and connect your phone, laptop, or tablet through Wi-Fi. It works like a mini router, sharing mobile data across multiple devices simultaneously.

Best for: Families, groups, or travelers with multiple devices that don’t support eSIM technology.

When to Choose eSIM

Opt for eSIM if you:

• Travel solo and only need to connect your own device
• Prefer not carrying extra hardware
• Want a quick and simple setup (activation in minutes)
• Need a cost-effective solution for individual use
• Have a newer device that supports eSIM technology

Example: A solo traveler landing in Tokyo can scan their Twise eSIM QR code at the airport and get online within seconds – no pickup counters, no extra battery to charge.

When to Choose Pocket WiFi

Go for Pocket WiFi if you:

• Are traveling with friends or family, and need to connect several devices
• Use devices like laptops, cameras, or older phones that don’t support eSIM
• Prefer having a dedicated Wi-Fi device for the group
• Plan to stay connected extensively throughout the day and need multi-device reliability

Example: A family on a European road trip uses a Pocket WiFi to keep all phones and tablets connected simultaneously, ensuring everyone can stream, navigate, and share moments without worrying about data sharing limits.

Twise Travel Tip

For some travelers, using both an eSIM and a Pocket WiFi makes sense. For example, you can keep the eSIM as a backup when the Pocket WiFi runs out of battery or loses signal, or use eSIM for your primary phone while sharing the Pocket WiFi with the rest of your group. This dual approach ensures uninterrupted connectivity in diverse travel scenarios.

Many Twise users choose eSIM for personal use and Pocket WiFi for group sharing. For example, a traveler in France activated Twise eSIM on their phone for personal browsing, while their family connected laptops and tablets through a rented Pocket WiFi. This way, they balanced convenience, cost, and coverage throughout the trip.

Conclusion: Which One Should You Pick?

When deciding between eSIM or Pocket WiFi, consider your travel group size, device compatibility, and usage habits.

• Choose eSIM if you want a simple, cost-effective, and hardware-free solution for solo travel.
• Choose Pocket WiFi if you’re traveling with a group or need to connect multiple devices simultaneously.
• Combine both for maximum flexibility on longer or more complex trips.
