When you have not obtained the unlock code because you do not fulfill the carrier requirements, you can prompt the unlocking on our website.
The easiest way to unlock a N9520 is to get the official unlock code thanks to our ZTE servers, when other SIM cards are inserted, and your ZTE N9520 asks you for the code; you must fill out the questionnaire and in a few hours you will receive an email with the unlock instructions.
We must indicate that sometimes the unfreeze MCK code is needed (when attempts are wasted, the mobile will prompt the - SIM network PIN blocked. Enter SIM network PUK - ).
