I can't seem to send SMS to certain contacts. I have tracker 2 installed but this is a recent problem. I am certain the mobile numbers I am trying to send to are correct.
Essentially I cannot click the send button. It seems to blink for an instant but it will not let me send the SMS. When I return to the SMS menu the message I am trying to send is saved to draft but with no mobile number in the to field.
Can anyone help? It's a real pain.
