Received a message telling me to upgrade my device asap
Hi, I'm one of the many Canadian AT&T prepaid customer and I've recently received a message telling me to upgrade my device asap or my service will be canceled on May 4th 2022. Also got the same notification in my online account.
My current device is a Galaxy S22 Ultra but the problem with it is that I have the Canadian version (SM-908W) which of course is not included on AT&T's list of compatible devices. Although I'm pretty sure there's no difference between US and Canadian models except branding and there wouldn't be any compatibility issue, the IMEI number of my device makes it incompatible with ATT network therefore triggering the messages to upgrade urgently.
Having my account canceled would be inconvenient because I'd be losing my phone number that I've been using for the past few years. Trying to prevent that, I logged into my prepaid account and tried to update my device there by putting in the IMEI number of a AT&T compatible device (someone else's phone - a family member who allowed to use their IMEI numberfor that purpose). That action was not possible from within my online account, I was prompted to call customer service and have them do the device upgrade for me. So I called customer service and I was actually offered a compatible device of my own, free of charge. They offered me a Galaxy S9 which by all means is a nice phone but my thought was I would use this phone's IMEI number to update my account and prevent it from being canceled and keep using my S22 Ultra while the S9 would be a backup phone. Problem is that according to an email I received after I placed the order for the AT&T device, once I activate the S9, my other device will stop working. I don't really understand how that works, do they match the S9's IMEI number with the serial number of the SIM card so they can only register on AT&T network while used together? 🤔
Sorry for the long story, in short my question is how can I keep using my Canadian device with AT&T? The workaround I thought of and described above seems to be unsuccessful.
