Important Instructions

* Before ordering makes sure that your phone is asking for the Netowrk Unlocking code when you insert a SIM card of a different carrier.

* Please double-check the IMEI before ordering. Due to ZTE policy we are not able to refund or replace orders if the submitted IMEI was wrong.  Make sure to use the IMEI from your ZTE Blade a520 obtained via Settings->About menu - not from its box as sometime are not matching. Live!

ZTE Blade a520


This specific service is genuine ZTE factory unlocking for ZTE Blade a520. Applying our product your ZTE Blade a520 will become similar with a never-locked one. Because of this network unlocking is permanent and general. You'll be able to safely update your cellular phone OTA as usual, factory reset as well as root or perhaps custom/stock firmware install.

Factory network unlocking your ZTE Blade a520 is legal and isn't voiding your cell phone warranty. To do the network unlocking it is not necessary any tech experience. You may complete it in a few minutes; you could be local or perhaps in foreign countries with or without carrier coverage. You don't have to employ a computer; all you need is simply a SIM card associated with some other carrier.
