problems with sending SMS
During the past 6 months or so, I have experienced problems with sending text messages. It is mainly with one contact - same number. For weeks, there can be no problems - I can send 10 messages in a day, and then suddenly, the message will not be send?
So I switch off the phone, re-start and same problem. ONLY with this one number.
sending text to other contacts is no problem.
We are talking text messages - not imessages.
No software updates pending.
Any suggestions on how to solve?
