About the unable to send sms problem. I had the problem once, before digi upgraded their services this time, and I couldn't sms for like 3 whole days.

Well... What I did was I went to a shop in KLCC lowest floor (don't remember name, but i know its some phone fixing shop that looked like a digi service shop, ie it was yellow in color.. lolz). Anyways~ I gave them my phone, they pressed some buttons, and told me I'll be able to use it in an hours time.

This actually happened to me twice already but both times this trick worked, So anybody having this problem and lots of free time, trying won't hurt ya?
