If you need to unlock a Samsung SM-J330F/DS Galaxy J3 from home, you should call the network provider who has sold you the device, 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.
The easiest way to unlock a SM-J330F/DS Galaxy J3 is to get the official unlock code thanks to our Samsung servers, when other SIM cards are inserted, and your Samsung SM-J330F/DS Galaxy J3 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.
It should be noted that to unlock a Samsung device, sometimes, the unfreeze MCK code is required (if the attempts are exhausted, so the mobile phone will show - SIM network PIN blocked. Enter SIM network PUK - ) or could be necessary the regional code RGCK (if you are going to use the mobile in another continent or region), in our company we also provide these unlock codes.

If the SM-J330F/DS Galaxy J3 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.
The United States AT&T, Cricket, metroPCS and T-Mobile carriers can lock the SM-J330F/DS Galaxy J3 and do not request the SIM network unlock PIN because they lock the devices through an application called Device Unlock, the app is usually already installed at the factory. You only have to order the unlocking and when server authorize us to unlock it, we will send you an email, just connect the device to WiFi and press Permanent Unlock within the application.
Normally a Samsung from Sprint, Verizon, Tracfone, Boost Mobile, StraightTalk or Simple Mobile from United States does not request the network unlock code, 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.
