Difference between iPhone 15 and iPhone 15 Pro eSIM support

All four iPhone 15 models have identical eSIM support -- the standard (15, 15 Plus) and Pro models (15 Pro, 15 Pro Max) handle eSIM in exactly the same way. The choice between them affects camera capabilities and screen size, not eSIM functionality.

Setting up iPhone 15 for travel

Install your eSIM at home on Wi-Fi before you travel. In Settings → Cellular, set your UK SIM as Default Voice Line (keeps your UK number active for calls) and the LimitFlex travel eSIM as your Cellular Data line. Turn on Data Roaming for the travel eSIM. Keep the travel eSIM toggled off (installed but inactive) until you land.

How to check your iPhone 15 is unlocked

Go to Settings → General → About and scroll to 'Carrier Lock'. If it says 'No SIM restrictions', your phone is unlocked and you can use any travel eSIM. If it shows a specific carrier, contact that carrier to unlock it before your trip.

Frequently asked questions

Can I delete a LimitFlex eSIM profile from my iPhone 15 after the trip? Yes. Go to Settings → Cellular → select the eSIM profile → Delete eSIM. This removes the profile from the device.
