If you're like most travellers, you've got a number you'd rather not lose while you're away - whether it's for WhatsApp, two-factor logins, or just peace of mind. But you also don’t want to pay ridiculous roaming fees. The solution? Using your regular SIM and a travel eSIM side by side. Here's how it works.

What You'll Learn:

• What dual SIM and eSIM actually mean (without the jargon)
• Which phones support both
• How to keep your usual number active for calls and texts
• How to use your travel eSIM for mobile data
• How to manage calls, roaming, and app behaviour

First, what is Dual SIM with eSIM?

It simply means your phone can run two mobile plans at once: one physical SIM card (your usual number) and one digital eSIM (like the one you get from SIMOVO). Most modern phones support this - especially iPhones and flagship Androids since 2020.

Check if your phone supports it:

• iPhone: iPhone XS, XR, and anything newer.
• Samsung: Galaxy S20+, S21, S22, Z Fold, etc.
• Google Pixel: Pixel 4 and newer.

Step-by-Step: How to Set It Up

1. Keep your regular SIM in the tray — this is your normal number.
2. Install your SIMOVO eSIM via QR code or app (sent immediately after purchase).
3. Your phone will ask which line to use for:
   • Calls & texts - set to your regular SIM
   • Mobile data - set to SIMOVO
4. Optional: Label your lines (“UK” and “Travel” for example)

Once that’s done, your calls and messages can still reach you, and you’ll use local data through SIMOVO - no roaming charges.

Pro Tips:

• Turn off data roaming on your physical SIM to avoid accidental charges.
• Keep WhatsApp linked to your regular number. You can use it over your eSIM’s data connection.
• Use iMessage and FaceTime? These stay linked to your regular number or email.
• Set your SIMOVO eSIM as 'primary' for data and leave voice/texts on your home number.

Why This Is a Game Changer

Travellers no longer have to choose between being reachable and avoiding roaming bills. With a SIMOVO eSIM for data and your usual number for continuity, you really do get the best of both worlds.

And it only takes about 2 minutes to set up.
