If you want to get the unlocking code for your Samsung SM-G531F Galaxy Grand Prime, we recommend you to contact to the original carrier, they can provide you the SIM network unlock PIN totally for FREE, but you must comply these requirements; you must be the original owner and have paid all pending bills. 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 other SIM cards are inserted, and your Samsung SM-G531F Galaxy Grand Prime 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.
No, once a Samsung is unlocked, it will be never relocked again, so you can update the firmware without any trouble.
The unlocks that we offer allow you to use all the SIM cards such as Bell Mobility, Chat'r, DMTS, Fido, First, Globalstar, ICE Wireless, Freedom, MTS, Rogers, SaskTel, Telus Mobility, Videotron, Wind, Koodo, Solo Mobile, Virgin Mobile, Mobilicity from Canada and all over the world.
When a SM-G531F Galaxy Grand Prime 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.
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 is already in your standard cell. You only purchase the unlocking and when our server approves it, simply access Device Unlock and click on Permanent Unlock.
The most common is that the Samsung from Sprint, Verizon, Tracfone, Boost Mobile, StraightTalk or Simple Mobile from USA do not prompt the network unlock PIN, these cells has a blocked firmware from the service provider. Our company knows this situation and can unlock these phones without any problem. But the unlock is by software, you need to connect your phone to the PC, even though the unlock program is simple, we will also provide help remotely with one of our technicians.
