O2: Can’t send text messages
Just had your number transfered to O2 and can’t send text messages? Don’t worry, this is normal for the first 24 hours (although it should start working much sooner than this).
Check your using the right message centre number to send messages. You can find these numbers on the O2 support site.
Another thing you could try is getting someone to send you a text message, this might start them working for you.
Dear IT guy
I see you give advice to those who can’t send text messages. Well it seems to me you’re having a little trouble yourself, cos you don’t send me many!!!!!!!!!!!
Love you
Yours in anticipation of maybe a text message soon
