Welcome to Android Central! Do you have mobile data on? Photos require mobile data to be on in order to receive or transmit.

Is the message being sent to you from an iPhone user?

hi again,im getting the same symbols from both my friends one which owns an i-phone and my other friend with a galaxy,i cant send a pic via text either it just says'' sending'' along side the pic and stays that way,it just began to happen a few days ago,kinda annoying that it all of the sudden its happening,ive gone as far as to reset my phone from scratch,dumb question,could it be a billing issue?that i can still send and receive written texts but not anything with a pic attached?i really dont want to be on the phone with customer service for hours and come out with nothing still,any help is apprciated

The other question I had was if you had your mobile data on.
