This seems to have just started being a problem in the last few days. My Moto e has just been telling me that messages sent from the Gmail and AOL account have failed to send, no error message or any further details! I am pretty sure I am within my data limit, and am on a monthly contract, so I don't know what to do to solve this. I am not naturally techy.... Have any clever people out there an idea what I should do now?? Please?
