Hey guys, sorry to open a new thread. This problem is quite rare, and I think its worth looking at.

Does your iphone suddenly jumps from phone already activated state to suddenly sim locked, then i have to type in the sim pin again to use the phone. This is weird, because its completely random, and I doubt it is because of low signal, the signal is full bar.

Boss, did you disable your sim pin lock option?

Hmm my sim pin option is set to On. But it should only ask me for sim pin only when i turn off and on back my iphone right?

Yes..i would say turn the option off and give it a try.

Cheers

hmm when this option activated, u need to retype pass code when ur phone goes sleep mode

Oh I see.. haha I thought it only ask when I restart iphone. Thanks alot.

great to hear that. i have this problem once where i did not turn of the sim pin and it will prompt to re-enter the pin. conclusion is, whenever the phone goes to sleep mode, it is almost the same as you turn your iphone off.

problem solve. please close this thread

happened to me sometimes bro
usually after I've get out from lift.
after recovering maxis signal, it will ask the pin code.

Nway i think most of u guys knew this already, even if u lock ur iphone with code, but anyone still be able to dial number as emergency call. haha.
