What are folks doing about AT&T’s planned shutdown of their 3G network in February '22 in the USA? They’ve told me that my FP3 will no longer work on their network (a guy in the store said they’re actually shutting down some 4G capability?), so they sent me a replacement phone and sent a message this week that they’ll be deactivating my current phone (my FP3) next week. Until now, I’ve had no trouble on AT&T. I’m trying T-Mobile, voice and text work fine but I can’t get data to turn on. Anyone having any luck with either AT&T or T-Mobile going forward?
