Can I retain WhatsApp number when using Twise eSIM?

Does Switching to eSIM Affect Your WhatsApp Number?

If you’re about to switch to an eSIM and are worried about losing your WhatsApp contacts or conversations, here’s some good news: you can retain WhatsApp number even after moving to a Twise eSIM.

WhatsApp accounts are tied to your phone number, not to your SIM card. This means even if you remove your physical SIM and replace it with a digital eSIM for travel, your WhatsApp account will continue to work seamlessly — using the same number you’ve always used.

So, whether you’re heading abroad for a few weeks or switching permanently to an eSIM setup, you can confidently make the move without losing touch with anyone.

How It Works

When you install a Twise eSIM, your physical SIM can be turned off or removed from your phone. But WhatsApp doesn’t need that SIM to stay active — it simply needs a stable internet connection.

Your WhatsApp number remains the same because it’s linked to your account on the app, not to the SIM card hardware. Once your number is verified on WhatsApp, it stays stored in the app’s settings and linked to your account data on WhatsApp’s servers.

That means:
 ✅ You can retain WhatsApp number without SIM card.
 ✅ You’ll still receive messages, calls, photos, and videos through your existing account.
 ✅ You don’t need to re-verify your number unless you reinstall WhatsApp or change devices.

This setup is especially convenient for travelers. With a Twise eSIM, you can connect to fast, local networks abroad and keep chatting with your friends, family, or clients — all while avoiding expensive roaming charges from your home carrier.

Why It’s Perfect for Travelers

Most international travelers face the same dilemma: “How can I stay connected overseas without losing my WhatsApp number?”

Using a travel eSIM like Twise is the simplest solution. You can deactivate your home SIM to avoid roaming fees while still being reachable on WhatsApp via data. Your chats, contacts, and groups stay exactly as they were before.

With Twise, you can:

• Retain WhatsApp number while abroad.
• Connect to high-speed 4G/5G networks in over 190 countries.
• Avoid juggling multiple SIM cards or swapping devices.

You’ll stay online for WhatsApp calls, messages, and media sharing anywhere you travel — as long as your phone has data from your Twise eSIM.

Important Things to Remember

Keep your original SIM active somewhere
Even though you don’t need it in your phone, it’s smart to keep your physical SIM active in another device or safely stored. If you ever need to re-register WhatsApp (for example, after reinstalling the app), you’ll need access to that number to receive the verification code via SMS.

Back up your WhatsApp chats
Before switching devices or SIMs, make sure to back up your chat history.

• On iPhone → go to Settings > Chats > Chat Backup > Back Up Now.

• On Android → go to Settings > Chats > Chat Backup > Google Drive.
  This ensures you retain all messages, media, and groups even if you reinstall the app later.

Maintain a stable data connection
WhatsApp requires internet — not your SIM card — to function. With a Twise eSIM, you’ll always have reliable mobile data abroad, ensuring your WhatsApp stays connected 24/7.

Twise Travel Tip

From real trips with Twise, travelers confirm: you can retain WhatsApp number, join groups, and send media exactly as usual — your contacts won’t even know you’re on eSIM unless you tell them. The experience is seamless, and you avoid the hassle of juggling multiple SIM cards.

If you’re traveling long-term, keep your original number active with a low-cost plan back home. That way, you can always recover your WhatsApp account if needed — while enjoying fast, affordable Twise eSIM data overseas.
