Hi Jashsu & coolbho,
Thanks for your replies... In that case, how should I get it unlocked?
Currently, I'll be using it in Singapore & I was not able to do anything on the phone.
Everytime I turn on the phone, it always request the SIM unlock code... & was not able to login Google to activate the phone.
Just to clarity, is it locked by T-mobile? Or sth wrong with the phone?
