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.
