I must be in the minority of people who have not had any issues with AT&T and are happy with their service and the price that I pay. I’m on the unlimited elite plan, which is $118/month (which includes cellular data on an Apple Watch). According to AT&T, on this plan the unlimited high speed data does not slow down based on how much you use. I also get 40 gigs of hotspot data which I use when I travel to connect my iPad. I generally go through about 30 GB per month. I also get HBO Max included, which is OK I guess. I did try T-Mobile for about 3 days a year and a half ago, and the 5G speed was so inconsistent, I canceled the service and went back to AT&T. Yes, it was really affordable, but within a 20 minute drive, my data speed would go from 70 Mb per second down to 3 down to 0.5. It was not a good experience.
