My second MTN Sim is blocked, and I don't have the sim park with me...I need the puk code....my number is 0554502004

sorry about your blocked Sim. I do not think MTN would be providing your PUk here. go to (https://www.mtn.ng/contact-us/) and you would be asked some security questions on usage and Sim registration details, once you are able to prove ownership of the Sim, MTN would give you your PUK.
