Please be informed that sometimes the unfreeze MCK code is also needed (when you try to dial the network PIN, LG will ask you the - SIM network PIN blocked. Enter SIM network PUK - ) and sometimes it requires the regional code RGCK (just at the moment when you try to use it in another continent). Don't worry, we always provide all the codes.

Why doesn't my K121 K4 allow me to make calls?

How to unlock a LG K121 K4 if it doesn't prompt for the unlock code?
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, 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.
The most common is that the LG from Sprint, Verizon, Tracfone, Boost Mobile, StraightTalk or Simple Mobile from USA do not prompt the 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.
