So, I just came back from a 3-week Euro trip. T-Mobile 5GB international fast data is per billing period, not per country. There may be a separate 5GB for Canada/Mexico, but not for countries in Europe. Every country we visited, we got the "welcome" text, but it is same 5GB as I can see them on my T-Mobile app. The app works fine for me in Europe. I don't need to use any VPN to access my account. My wife and kid used up their 5GB in about 5 to 7 days. They were both steaming videos. I only used about 2.5GB in 3 weeks. But even after the fast data were gone, they were still able to do most things with the 256K speed. They can even stream Spotify with that speed. I was offering to buy them extra fast data, but they both declined.

Back to topic of the thread. I am the only 1 of the 3 who has a Pixel 7 which could do hotspot in WiFi only mode. It is very useful when you need to purchase WiFi or if Sign-In portal is complicated. It is so much easier to just sign into WiFi with my phone, and have other devices connected to my phone's hotspot. I also found out one thing about WiFi that I didn't know before on this trip. If there is a WiFi connection with a very long password, you could just type it in once on your phone, then share it with a QR code to other phones that needs connection. It saved so much time.
