Kburkett , via OnePlus 8 Pro , Jun 3, 2020 : I have a brand new OnePlus 8 pro which is now basically a very expensive paperweight. I cannot make phone calls and when I finally connect the call is dropped. this is so very frustrating. The phone is supported by TMobile even though I bought it directly from OnePlus. I just switched my sim from my old OnePlus 5 to the new phone. I wonder if there's something wrong with the network?
