Hi,my Samsung Galaxy A5 has suddenly started to "failed to send message " to acertain number. Our phones were blocked both sides but are no longer. They are able to send me a text but I'm unable to reply..... can anyone help please? x
Yea could be, what you could also try is re setting network settings. If you go into settings, general management, reset, and then reset network settings. One other step you could try is re setting the app preferences. do this by going into settings, app, tap on the three dots in the top right hand corner and then reset app preferences. Hope this helps.
No i reset network settings and app settings but that didn't solve it. I contacted O2 who said I must be blocked by the other person. They have checked and I'm not. I can call the number. Very strange!
