eSIM and iPhones

I think it depends on your phone rather than your carrier. The newer iphones allow for two e-sim and a regular sim card. In past years, I used use those paperclip things to remove my US sim card and put in one I bought in a train station in EU or via Amazon (from UK) in the US. But this last trip I used an e-sim - and never removed my US sim card at all - but with mixed results. You download their app, pay for a time period, and then its authorized in some way - which requires wifi. It seemed to work about 2/3 of the time in multiple countries.

There are a bunch of YT videos of various guys talking about some of the main companies which have these apps. I could mention them here is there are no objections but I am not sure I would guarantee great service. But on the other hand, the trip before last, I used my US plan and could not get reception half the time, and it was so bad, that i got my phone replaced in France (free of charge).

I don't know what the ideal solution is anymore.

What kind of iPhone do you have?

Older models (eg iPhone X) can't use eSims.

Try googling "is an iPhone [your phone model] compatible with eSIMs?"

What version of IPhone? Does it have an eSIM option? If so it's probably your carrier that won't allow it as your phone is probably locked.

According to Apple iPhones starting with model XS are eSIM compatible. If your phone is carrier unlocked you should be able to use an eSIM. For the UK you can get one through GiffGaff. Download the app from the Apple App Store. Very easy to set up and get running. Look for a pay as you go plan.

Have a fun trip.

Unfortunately my AT&T plan is the problem. I have a different phone that is unlocked and eSIM compatible. I used airalo in Canada with success. I will try airalo for England since the AT&T plan is so so expensive. I can’t go without data because of my heart monitor. When I return I’m going to try again with AT&T to unlock the phone. Thanks everyone!!

If your phone is fully paid for you should be able to get ATT to unlock it.
