If you need to unlock a Samsung G710 Galaxy Grand 2 from home, you should call the network provider who has sold you the device, 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. 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 Samsung G710 Galaxy Grand 2 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 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, the unlocks we provide will never be removed, and you can update and restore the Samsung whenever you need it, without fear of losing the unlocking.
Our unlock allows you to use any SIM from Three, Eir, Vodafone from Ireland and all countries of the world.
When a G710 Galaxy Grand 2 does not reject your new SIM card but does not allow you to make calls, it is most likely that the IMEI has been blacklisted. You need to contact with the carrier to solve it.
Some AT&T, Cricket, metroPCS and T-Mobile mobile phones in the USA do not require an unlock code, they are locked with an app pre-installed in the device called Device Unlock, 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.
