It should be noted that to unlock a LG 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.

Unlocking method is for any SIM card of Optus, Vodafone from Australia and any other country.
Why doesn't my K40 allow me to make calls?
When a K40 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.
My LG K40 does not prompt the unlock code and is locked with a United States carrier
The United States AT&T, Cricket, metroPCS and T-Mobile carriers can lock the K40 and do not request the SIM network unlock PIN because they lock the devices through an application called Device Unlock, 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 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.
