I changed the sim card in the phone that didn't work. When I put the sim card that works into the other phone it will work in that phone but the new sim card doesn't work in either phone. I changed the sim number in the proper account but it will now...
the carrier profile shows public mobile and we it works when I text his phone. When we put my sim card in his phone it works but does not work in my phone when I put the new one in it. I changed the sim card number on his account
