My AIS 1-2-Call prepaid SIM card has been locked and I can't find the PUK to unlock it. Is there any way (or some clever techo) that can unlock it sans PUK? Preferably in Udon.

Any help will be appreciated.

Did you try the below? Not sure if it works.

"Just insert the blocked sim inside phone, then remove it and switch off the phone. and insert the blocked sim in the phone again and switch on the phone. then press this code: *22233421# . after that press the new pin you wish."

Thanks Makloey. Tried but doesn't work unfortunately. Back to the drawing board!

Go to AIS and get a new SIM and get the same number (will cost you the price of a new SIM, still they are pretty cheap)

Thanks Newcomer, will do. Pity to lose all my contacts on the locked sim tho'.

when inserting the new sim..the contacts may have been stored on the phone...most phones have contacts stored to phone and sim memory

just go through the phone and find..copy contacts.. from phone memory...then this will put all the phone contacts on the new sim

what phone is it

AIS should be able to tell you the PUK number as long as the SIM is registered.

Thanks hotrod4098. Phone is Lenovo A369i.

Deke, I'll try AIS but not sure if the sim is registered, can they tell me?

Thanks newcomer01, did that, all ok now incl all my old contacts to new sim. And no charge!

No problem. Nice to have a win. Sometimes things can be easy.
