I rarley follow this forum as my wife wont let me touch her moto x, so this is a non-rooted unlocked addition bought direct from Motorolla and used with T-mobile US.
Her issue has been intermediate and not always reproduceable, sometimes when she sends MMS they arent recieved but about 70% or more are. and about 99% of here SMS are recieved when sent.
Issue has been present since day one (about 6 months ago now) and she only now has gotten fed up and wants a fix. She mostly uses hangouts but issue is present when using defult android messaging app as well.
APNs look correct, T-mobile blames Motorolla and Motorolla blames T-mobile.
I was hoping someone would know if this is a common issue or know of a fix or know if there is someone who really is at fault (other than me for only doing minimum searching before posting this thread - at work now but pregnant wife needs a fix now...)
any help would be much appreciated!
