So my father is with Public mobile and he’s currently in Mexico. I let him know he can manually change the tower he’s connected to, and I guess he attempted to do this on his own. He’s now called me and told me he can no longer connect to public mobile. I admit, my father is in his 70s, and not familiar with technology. If someone could kindly write up some instructions on how to turn his roaming back on I would greatly appreciate it. He has a samsung and I’m also unfamiliar with Androids, being a long time iphone user. I tried to assist and that led to more frustrations. Thanks in advance!
