answer is no. Sims are required now typically to even have an operating phone. They serve as a forced way for pay per usage to force install still, track, and require phone uptime for a long ping time sequence which shows them you're operating the phone and it works. they can force update patch needbe. And they will sever a phone that has no data being sent to it no matter what method they try to locate it within max ten days off and they require first five days of month for phone to be active to be within its usage term requirement
