iPad works good on wi-fi. On LTE it’s iffy. Sometimes it works, sometimes it works slow and sometimes not at all. I have AT&T as a provider with my iPad and my cell phone (iPhone 12 mini) on the same plan. The iPhone works great and when the iPad doesn’t work I hotspot off my phone and everything is ok til I run out of hotspot data. So I don’t think it’s a carrier problem, it’s more of a receiver problem. What do you think?
