My T-Mobile data isn’t working
I have an iPhone 12 pro max (it’s on the latest IOS version) that can make and receive calls and texts, but the cellular data won’t work at all for things like Safari, social media, or any other app ...
You need to install a TCO/IP PING diagnostic app and run a PING test to 8.8.8.8 to see if data is working at all. If not, you should check to make sure that data is both turned on in the phone and provisioned in the switch (your account settings). I've recently heard of another person whose account spontaneously lost provision for data and it was eventually tracked to a setting deep down in the account provisions. Something Tech Support had to find. Probably the hardest thing was getting past 1st level CSRs to get to Tech Support.
We had the same issue and figured it out. It was due to vpn we had active on the one device. T-Mobile appearantly doesn't support VPN over data. Hopefully this helps someone else.
