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.
There’s at least one way to reverse it, by wiping the phone clean during a total reset, like what you would do if you sell the phone.
I would consider doing that but I’d rather not have to go through the process of re-downloading all my apps and re-customizing my phone just because I disabled a potentially important app.
