Has anyone used it there? I looked on their site and they seem to cover Iceland, but wanted verification from people who've been there.
I had Sprint which is basically T-mobile now since they were bought out last year. I went to Iceland in June and my phone worked fine. 2G internet was a bit slow but was enough to get maps going and my mom actually managed to stream some things with it when we were out exploring. Texts and WiFi calls/FaceTime audio wasn’t an issue at all.
I've used T-Mobile in Iceland a few times. No real problems as above but internet is slow.
I have T-Mobile and in 2018 used their default slow connection for GPS and Whatsapp calls everywhere (Drove the whole circle).
I am in Iceland and have t-mobile. It works fine. Texts and data are free, phone calls are 25 cents per minute.
We used t mobile in iceland in 2019. Don't recall any problems, texting is what we mainly used and like another poster said if you want to make calls, use what's app.
We used Tmobile all over Iceland with no issues. (Aug-Sept 2021)
