When I try and send an sms, the line gets 90% to the end of the bar, then writing appears, saying "error sending message" and the message does not get sent. Anyone know howto fix that bug?
I had the same issue with a specific contact on my iPhone, I can send the messages to other contacts. I deleted all the SMS history that I had of this contact and after that I can send messages again.
Keep pressing the send button every time it fails and make sure you're in an area with decent service. This happens to me sometimes, but I can almost always get it to send by continuously retrying when it fails.
