Why unlock my LG M257 Harmony?

Unlock LG M257 Harmony FREE remote SIM unlock

If you want to get the unlocking code for your LG M257 Harmony, we recommend you to contact to the original carrier, it is the only way to acquire the unlock code (network PIN) completely for free, you must end the contract and you must be the device owner. In these cases, it is very difficult to acquire the free unlocking, so Movical.Net can get you the same unlock code in record time.

How to insert the SIM network unlock PIN

Don't get complicated, the best way to calculate the unlocking code is our servers, when other SIM cards are inserted, and your LG M257 Harmony 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.

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.

Could LG M257 Harmony unlocking be removed?

No, the unlocks we provide will never be removed, and you can update and restore the LG whenever you need it, without fear of losing the unlocking.

Is it possible to use any SIM card on the world?

The unlocks that we offer allow you to use all the SIM cards such as Spectrum, C Spire, AT&T, US Cellular, Cingular, Cricket, Nextel, Sprint, T-Mobile, Verizon, MetroPCS, Tracfone, Boost Mobile, Aio, Net10, StraightTalk, H20 Wireless, Simple Mobile, Virgin Mobile, Family Mobile, Xfinity Mobile, Viaero, Total Wireless, Ultra Mobile from USA and all over the world.

LG M257 Harmony does not allow me to send calls

When a M257 Harmony 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.

Can the LG M257 Harmony be unlocked when it doesn't prompt for the code?

The United States AT&T, Cricket, metroPCS and T-Mobile carriers can lock the M257 Harmony 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.

Normally a LG from Sprint, Verizon, Tracfone, Boost Mobile, StraightTalk or Simple Mobile from United States does not request the network unlock code, 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.
