I’ll be traveling to Italy in September. I have an iPhone 13 Pro with an eSim, on T-Mobile. while I know I can pre-buy international plans from T-Mobile including those with data, on my last trip in 2017 I found that the data speed availability (then with my iPhone 6S) was 2G if lucky, and generally below; that was essentially useless. I don’t know which carrier(s) T-Mobile uses in Italy, but it was dreadful.
For this year, I’m considering buying a SIM card over there. However, since I don’t have a SIM card in my phone now, I don’t know how this is going to work. Will it totally disable the eSim? Will I have to go back to a T-Mobile store in the USA upon my return to make the eSim work again? Or, will it revert to the eSim when I remove the Italian SIM? Will I have to “wipe my phone” in order to do any or all of this?
I want to use the phone for navigation while over there, so reasonably good data is essential. I could barely get email or messages over 2G back in 2017 and do NOT want that again.
Suggestions?
