Removing GSM Sim Lock in LG Fathom?
 

Sim Lock in LG Fathom VS750 is controlled by SimLockSerurity.dll.
It is possible to disable loading of this file using Registry Key.

In the following Registry Key,
HKEY_CURRENT_USER\ControlPanel\Phone\SecurityTab
you will find key
ExtendedPIN
with value
\windows\SimLockSecurity.dll

Just rename the value "SimLockSecurity.dll" to Some other Name,
for example:- \windows\OriSimLockSecurity.dll
Save & Restrart the Phone.

After restarting the phone, "SimLock" menu doesn't appear in
Phone Security settings tap.

My phone originally came with sim-unlocked state. After disabling
SimLockSecurity.dll, my phone works as usual.

Those who have their phones with GSM SIM-LOCKED, please test this
settings & Reply whether this settings removes the SIMLOCK.

You have to use any one of the Registry Editor
Software for editing Registry.
I am not sure this trick will unlock your phone.

I would like to try this - has anyone else been successful?
I need to unlock the SIM for GSM use in Europe.
Thank you.

EDIT: In my phone, I do not seem to have a "Security Tab" folder or an ExtendedPIN reg key. Any tips on where to look or how to fix this? Thanks again

Search for
SimLockSecurity.dll
through Registry. If you find it just rename it
& restart.

Please check & reply.

This trick just makes the sim lock option disappear ....but it still gives error of invalid sim for non verizon sim in gsm locked phone and the sim doesnt work.

So is there any way to unlock the SIM for a USA Verizon locked LG Fathom? I just want to stop looking if there really is no option out there.
Thank you.

well.....i had almost given up as almost every unlocking site i tried failed to deliver an unlock code.....it was going to be more than a year since i bought this locked phone.....but i gave a last try on ebay.com
UNLOCK CODE FOR LG VS750 Fathom Verizon CDMA Phone World Phone UNLOCKING SIM | eBay
since the feedback of the seller was good i bought the service, mailed them my imei and in about 5 minutes a mail popped like

"IMEI : 359943030222317

Unlock code: NCK: 20089438


If there are multiple codes, please refer to instructions link on which code to use (NCK or Network is usually Unlock Code"
And i got flabbergasted to see the message of "sim lock disabled" after entering the code!! :) good luck

Wow - that is great news! One question, I went to the ebay listing and it says "does not work on USA GSM". I don't know if you are USA based, but, if so, does it work here? I just don't want to get to Europe and find out it doesn't work.
Thank you.

I know the phone is designed to work on non-US GSM networks (otherwise Verizon would have never put a GSM modem into their phone.)
I also know that it does work on US GSM networks, as I have one running on US T-Mobile.
