Hi folks ... as a relative amateur, can anyone please explain exactly what the NCK & SPCK are? .... I believe NCK = Network Code Key which is also know by other names like NP code or NUK or NUP or NUC ... am I correct?

I have no idea about SPCK ... please enlighten us amateurs !
Thanks in advance

Thank you Ashif ... now I am confused !!!

What is the difference between "Network" (N) & "Service Provider" (SP) ?

I recently received NCK & SPCK for a locked ZTE phone.
Neither worked ..... but please explain which one I should use.
My service provider is the same as the network = T-mobile (UK) .. I think !

Thanks

in most cases u would use the NCK - Network Control Key

Phones can be locked like this

Network Lock
Service Provider Lock
Corporate Code
Phone Code
Network Subset Lock

for example..

however if both your codes are not working id check if youve been given the right code and also if your putting in correctly

Thank you GSMman187 ..... much appreciated response.
I did as you suggested .... got same results .... changed SIM card and voila! ... it worked using NCK .... excellent. Many thanks for your info. maybe it was a bad SIM card earlier? .... anyway, thanks for the info.
