Hi Hotlink,

Can you please PM me for info you need.
My number is still active and will not expire before next year.
However, it cannot register to Maxis network anymore since 2 days ago.
I suspect it is being deactivated for whatever reason.

Thank you for the PM.
I went to Maxis Center @Queensbay Mall before I saw your message.
Customer Service there is fast, maybe due to CNY, not many customer there.
According to the CS personnel, my account is still active without any problem.
Then, he took my phone and take out the SIM card for inspection.
My SIM card was trimmed from normal sized to micro SIM.
His theory is that the air somehow got into the SIM card and oxidized the chip inside.
Wow, that is the first time I hear this theory.
I don't know, he could be right. I've been using the trimmed SIM card for 2 years without problem.

Anyway, he replicated a new 128K SIM card for me with cost.
The network came up straight away.
So, my case is now mark solved.
