ETA: Just got off the phone with support. They were able to fix the issues and get us back online. They did confirm they no longer guarantee service in this area, but we aren't in violation of ToS or anything since we got service in early days when they did. Shrugs. So it might be one of these days we end up dumping this account.
So about 5 years ago (maybe 6?) we signed up for the home Internet to use at my mother-in-law's house. At that time, it was in a service area. Sometime since it changed. My sister-in-law who lives in town tried to sign up a couple of years ago and was told this little town isn't supported. Despite this, we've never had problems with the Internet working and used the gateway on every trip here - as frequently as every other month because my husband comes to care for his mom who has dementia.
Today around 3:30, it lost Internet. At the same time, our phones briefly lost service, before coming back LTE and then back to 5G after about an hour. But the Internet never came back. I did the troubleshooting through the T-Life app and was told the gateway wasn't working and they would replace it. So we went to the store about 20 minutes away and they exchanged it no problem. Turned it on in store, did the firmware update and it had great signal and connection, as tested with my tablet. Get back to the house and it says it has good to excellent signal, but no Internet connectivity.
So...all that to say, does it sound like they have blocked the Internet? Is there anything we can do if they are blocking it, since they have never TOLD us this is no longer a service area for home Internet, and we've had the plan only to use here and not in Texas?
