If you want to get the unlocking code for your Xiaomi Black Shark 4, we recommend you to contact to the original carrier, 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.
Don't get complicated, the best way to calculate the unlocking code is our servers, when other SIM cards are inserted, and your Xiaomi Black Shark 4 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 warn you that your Xiaomi have 5 attempts to dial the unlocking code. Our code will not work if the phone does not request the (SIM network unlock PIN). In this case, it will be necessary to reset your cell phone and the price will be more expensive.
No, our unlock is never removed, you can update your phone as many times as you want or even reset your mobile.
Unlocking method is for any SIM card of Spectrum, AT&T, US Cellular, Cricket, Sprint, T-Mobile, Verizon, MetroPCS, Tracfone, Boost Mobile, Net10, StraightTalk, H20 Wireless, Simple Mobile, Virgin Mobile, Family Mobile, Xfinity Mobile, Viaero, Total Wireless, Ultra Mobile, Visible Wireless, Consumer Cellular from USA and any other country.
Most likely, the device has been reported for non-payment, loss or theft and the IMEI has been blacklisted. Our unlocking does not remove reports and you would have to contact the network provider.
The most common is that the Xiaomi from Sprint, Verizon, Tracfone, Boost Mobile, StraightTalk or Simple Mobile from USA do not prompt the network unlock PIN, because these phones have a blocked firmware with the carrier. Our company solves this block and removes this restriction, but it has to be unlocked with a program on the PC and our technician will help you remotely.
