So, Verizion, AT&T, Sprint, T Mobile, Minto, Tello, Ting, Cricket, U.S. Cellular, Cellular One Etc. will NOT work with the Chinese ( DCO-AL00 ) version of the phone.
IMEI check with their websites and you will find this phone has not been registered within their database and therefore will not work (even though technically this phone can, with some exceptions of incompatibility being verizion and the like)
I have found an answer after trying multiple sim cards (AT&T, Sprint, T Mobile, Ting etc)
At 1st, the only viable option i found was buying a Chinese service meant for traveling overseas which cost $100+ a month for basic service)
The answer is Lyca mobile. 3 dollars for the sim, $40 for unlimited data plus full high-speed connectivity in the US.
Just wanted to put this out there because i could not find a solution ANYWHERE on the net before i found out the answer myself via trial & error. I consider this the best phone of 2022 hands down, and worth the fight to figure this out. And here is the affordable service that is compatible.
Im Also aware that the Mate 20, 30, 40 & P30,40 & 50 all work with some of the carriers that were mentioned that did not work for the new Mate 50 pro, so this information is for the DCO-AL00 only.
