When you require the ZTE Blade A31 unlocking code for free, it is necessary to contact the service provider that has blocked the mobile, it is the only way to acquire the unlock code (network PIN) completely for free, you must end the contract and you must be the device owner. Our company is dedicated to calculate unlocking codes by IMEI, we work with official unlocking servers and we send the same code as the carrier.

You need get the unlock code filling out the form and making the payment, shortly you will receive an email with perfectly detailed instructions on how to enter the unlock code.
Please be informed that sometimes the unfreeze MCK code is also needed (when you try to dial the network PIN, ZTE will ask you the - SIM network PIN blocked. Enter SIM network PUK - ) and sometimes it requires the regional code RGCK (just at the moment when you try to use it in another continent). Don't worry, we always provide all the codes.
