Hi, I'm not able to send text messages using my Samsung Android phone on the TPG/Vodafone Network.  I can receive but cannot send to anyone. I checked my balance, my active plan- Sending SMS and Receiving SMS- active, Service Center Number is set to +61415011501, checked Network Provider, tried rebooting the phone, tried to restart and then send SMS to my own number, tried TPG SIM in a different handset that is known to send and receive SMS properly. Nothing works. Contacted TPG mobile support on several occasions. They could not help.    If someone can help, would be much appreciated.   Thanks, Alex. ... View more
