That depends on the speed and quality of the WiFi Internet connection. T-Mobile’s WiFi Calling is fairly persnickety about the WiFi and Internet connection. I’d suggest having some other VoIP apps (e.g. Viber, Signal, WhatsApp) as a backup. Texts will almost certainly work. If you use WiFi calling onboard be sure to put the phone in airplane mode and turn the WiFi back on.
Depends on where you are going. I was told I would have service in Alaska, absolutely none. You could tell who had Tmobile on board, we were the people paying AT&T and Verizon customers to use their phones.
When I went to Alaska a few years back, I had T-Mobile service (roaming). T-Mobile brags about its roaming with GCI in Alaska.
Might be different if you’re on Prepaid.
