When you require the Samsung Galaxy A51 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. When you have not obtained the unlock code because you do not fulfill the carrier requirements, you can prompt the unlocking on our website.
The easiest way to unlock a Galaxy A51 is to get the official unlock code thanks to our Samsung 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, once a Samsung is unlocked, it will be never relocked again, so you can update the firmware without any trouble.
Unlocking method is for any SIM card of Optus, Vodafone from Australia and any other country.
If the Galaxy A51 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.
For most new AT&T, Cricket, metroPCS and T-Mobile models in the United States, the unlock method is different, it does not prompt the SIM network unlock PIN and uses the Device Unlock application, this app is already installed by default in the device. You have to buy the unlock and we take care of the approving authorization to unlock it. Once approved you only press the Permanent Unlock button and it will be unlocked forever.
A Samsung from Sprint, Verizon, Tracfone, Boost Mobile, StraightTalk or Simple Mobile from United States will not prompt the network unlock PIN, these handsets are blocked by the network provider's customized firmware. We also support this block, but is necessary to connect your mobile to the computer and use an unlock software.
