Most of the android phones I’ve had came preinstalled with something called “Mobile Services”. I normally remove it because it just keeps randomly installing apps and games that don’t want but I’ve never had an active phone plan on those phones. If I disabled it from my phone, would I still be able to send and receive calls and texts?
So far the only thing I have found out is that “Mobile Services” is an app that is only preinstalled on android phones who’s carrier is Tracfone.
It’s not the account that I’m worried about. It’s hard for me to explain what I’m actually concerned about. I guess an example would be that the SIM card becomes invalid or something. One of the phones where I disabled Mobile Services has an effectively permanent error at the top of the screen that says “invalid SIM card”.
