See above where I asked them during each interaction (usually more than once) whether the device was supported on their network. Also note that they replaced my device. Why would they send me a device that would no longer work on their network three weeks later? Also, after swapping SIMs back and forth with my iPad, the ZTE 64 is once again working. I believe that TM is running a script that checks when the device first joined the network, and how long it's been since the device negotiated a 4G LTE connection. If joined after 8/1/2021 and no LTE for a week, the device is banned. Swapping the SIM into a different (LTE capable) device resets the one week timer. As an aside, I can see that some of TM's cell sites are still advertising 2G service. Press releases from last year said they would support 2G/3G service until December 2022. Now the press releases are saying they will shut those down at the end of this month.
