Hi ! Since I joined with 48 it's says on my phone that I have full bars of coverage when I am in an area with good coverage but yet my message doesn't send. This is extremely aggravating as I think an important message has sent but it has failed and I don't notice as it says Iv coverage ? Also someone will try and contact me and they cannot get through even though it says on my phone that I have coverage and am not in a bad area with no coverage . I then have to repeatedly turn on and off airoplane mode . This is becoming very annoying and not efficient . Is there anything ye can do with this on going problem? Paula
