Do I need to switch my SIM card to eSIM?

By the VoyaSIM team · Updated October 31, 2026 · 2 min read

Quick answer

No. Keep your SIM card in the phone: the VoyaSIM eSIM is added next to it, and your number stays on the SIM card. Moving your home line from a SIM card to an eSIM is something your own carrier does, and a trip does not need it.

01

Moving your home line to eSIM

  • iPhone: Settings → Cellular → Convert to eSIM, where your carrier supports it; otherwise the carrier sends you an eSIM QR code.
  • Android: carriers do it in their app or in a store, and on some phones Settings → Network & Internet → SIMs offers “Convert to eSIM”.
  • Do it at home on Wi-Fi, before the trip: if your carrier sends a confirmation code, you need to receive it.
02

Changing phones

A VoyaSIM eSIM installs on one phone. If you have not installed it yet, scan the QR code with the new phone. If it is already on the old phone, write to support@voyasim.io with your order number before the plan starts: an installed QR code can't be moved to another phone.

FAQ

Frequently asked questions

How do I take the SIM card out?

On most phones, push the eject tool or a paperclip into the small hole next to the SIM tray. For a travel eSIM you do not need to: keep the SIM card in for your number.

My phone already has a SIM card and an eSIM. Can I add a travel eSIM?

Yes, eSIM phones store several eSIMs. On most phones two lines can be on at a time: switch on your home line for calls and the VoyaSIM line for mobile data.
