If you need to unlock a ZTE Grand X4 from home, you should call the network provider who has sold you the device, because it is the only way to obtain the SIM network unlock PIN for free. You must know that you need to fulfill the carrier's requirements, such as being the cell phone plan 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.
The easiest way to unlock a Grand X4 is to get the official unlock code thanks to our ZTE servers, when we introduce SIM cards from other carriers, the mobile phone prompts the SIM network unlock PIN, so you must order it on our website and you will receive perfectly explained unlock instructions in record time.
It should be noted that to unlock a ZTE device, sometimes, the unfreeze MCK code is required (if the attempts are exhausted, so the mobile phone will show - SIM network PIN blocked. Enter SIM network PUK - ) or could be necessary the regional code RGCK (if you are going to use the mobile in another continent or region), in our company we also provide these unlock codes.
Certainly not, our unlocks are official and forever, you can update Android without any problem.
Unlocking method is for any SIM card of 3 Hutchison, O2, Orange, T-Mobile, Tesco Mobile, Virgin Mobile, Vodafone, EE, BT Mobile from United Kingdom and any other country.
If the Grand X4 accepts the SIM card but does not allow you to send or to receive any call, it could be because the IMEI is blacklisted due to loss, theft or unpaid bills. Even if SIM unlocking is achieved, it is necessary to fix the IMEI problem contacting the carrier.
