I will of course, tried again later. Just curious if I'm the only one having this problem, or is this a common problem.
I live in Indonesia, using Telkomsel. One of my friend using the same service and he have no problem setting it (few months ago).
Edit : Solved, the verification codes reach my phone, like 20 of them at same time. lol. Of course now I have problem linking paypal to my account. sigh.
