Orange burn their code into your sim?Update.....
Tried all methods I could... the MCC just remains as the overseas MCC and not that of Singapore.
Orange is mega stubborn and refuses to leave.
Went down to Simba OC today, and after a mere 2mins, Simba changed a new sim for me...
They could not resolved as well... so to save time and energy, change new sim... easy way around...
