When you require the ZTE Z831 Maven 2 unlocking code for free, it is necessary to contact the service provider that has blocked the mobile, they can provide you the SIM network unlock PIN totally for FREE, but you must comply these requirements; you must be the original owner and have paid all pending bills. When you have not obtained the unlock code because you do not fulfill the carrier requirements, you can prompt the unlocking on our website.
Don't get complicated, the best way to calculate the unlocking code is our servers, when you put SIM cards from other network providers, the phone will require the unlock code, if you want to get it in a few hours, order it and we will send it to your email.
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 - ). Other different case, is if you need to use your phone in a different continent, in this case it will be requested the regional code RGCK, you should not worry, our company already knows these cases and always send you the necessary codes for a perfect unlock.
No, our unlock is never removed, you can update your phone as many times as you want or even reset your mobile.
Our unlock allows you to use any SIM from 3, Access Telecom, Airtel - Jersey, Clever Communications, eMobile, Meteor / Eir, O2, Tesco, Vodafone - Eircell from Ireland and all countries of the world.
This is frequent when an IMEI is reported in blacklist for unpaid bills or theft. To solve this problem, you must call the carrier that reported the blacklist.
1. - Turn on the handset on with a SIM card not accepted by the device (your new network operator)
2. - If the card has a PIN number, enter it and press OK.
3. - The device will prompt: “Network lock”, Now enter the code and press OK.
4. - Your phone will indicate: "Unlock successful", becoming permanently unlocked.
