Hi guys, a friend of mine just bought iPhone 4 couple days ago. Today he had some problem sending out messages.
The SMSes can't go through at all with the notification saying "your message can't be sent out" or something like that.

He had cellular data turned on as well but still can't work.
Oh by the way, he can make phone calls just perfectly fine but texting doesn't.

Anyone know any solution to this? Thanks.

Yeah he's with Maxis. Just got the plan couple days ago.
Thanks for your advice, will let him know.
