What Is The Puk Code For T-mobile Sim Card?

PUK stands for Personal unlocking key and it si your Personal Code which means it is not accessible by anyone and thus no outsider can give you this code except for your cellular operator. To Get PUK Code, Call your cellular operator's helpline or visit their customer service center. PUK code is usually provided free of charge but very few operators in some countries charge for that.
PUK is a SIM dependent feature rather than Phone dependent. Had you be in need of Phone Lock Code, you could be provided that. But, In case of PUK code only your cellular operator can provide that because it is related to SIM. Also PUK code is needed continuously but Phone Code is usually used once because when Phone is unlocked its code might not be of any use.
