If you want to get the unlocking code for your Samsung Galaxy Tab A SM-T357T, 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. When you have not obtained the unlock code because you do not fulfill the carrier requirements, you can prompt the unlocking on our website.
Don't get complicated, the best way to calculate the unlocking code is our 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.
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, our unlock is never removed, you can update your phone as many times as you want or even reset your mobile.
Our unlock allows you to use any SIM from Optus, Vodafone from Australia and all countries of the world.
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.
On some occasions, the AT&T, Cricket, metroPCS and T-Mobile phones do not prompt for the unlock code and are locked with the official application 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.
The Samsung Galaxy Tab A SM-T357T from Sprint, Verizon, Tracfone, Boost Mobile, StraightTalk or Simple Mobile from United States also do not prompt for the SIM 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.
