Switched to ATT from Verizon because I couldn’t get cell service in my house with Verizon (not in the boonies, just a weird dead zone) and because they just installed ATT fiber, and they were doing crazy offers last year so ended up getting two new iPhones, and ~$200 to switch to their wireless and internet. No problems so far, but I know they’re not the most savory.
If think they’re probably having a pretty rough time
