SMS sending problem with A1200

[emomvp1978]

Hi, guys
I got a big problem with my Motorola A1200. A week ago it was everything fine, just had some small problems, but nothing very important. Now I CAN'T send SMS and it's very important for me to solve this problem. All the settings with my Mobile operator is fine. The problem is: I go to Messeges->Compose-> To (write the number) choose: sms in the upper left corner, then I start writting the message, when I'm done click on the SEND button and nothing happend!?? It doesn't say Error or something. The button animation show that I press it, but it doesn't start sending. So I think that the problem is definetly in my phone software, not somewhere else.
If someone got an idea what I can do to fix the problem, please help.
I bought another very cheap phone just for SMS, but I want to use my Ming 'cos I love it.

If restarting phone doesn't help (I think you did it) maybe a master reset will do. Don't forget to backup your phonebook with MPT first.

I did master clear. Will try with master reset. Tx
