To unlock the password on your LG Cosmos, you need to re-program your phone. This will default the code to the last four digits of you cell phone number.

You First need to temporarily activate the ESN (also known as MEID, HEX) off the back of your phone underneath the battery to you Verizon Wireless cell account.

You can change the ESN (Electronic Serial number) as follows:

1.) Verizonwireless.com

2.) Dialing *228 opt. 1 from the phone you want to activate, while the current activated phone is off

3.) by calling customer service to temporarily activate the phone (1-800-922-0204 or *611 from a Verizon Wireless handset not involved.

(note: most all phones, even if their locked should still be able to call 911 and the programming number (*228)

You can activate the phone for a day to an existing account just to do this if necessary.


Once you change the ESN on to a phone number and program it
Dial *228 on your phone, listen in and pick option 1 for programming.
after listening to music for about a minute or two you should hear "programming completed successfully"

Once you hear this you can hang up the call. The phone should reboot by itself.

If not power it down manually and then power it right back up.

now you should be able to unlock the phone with the last four digits of you cell phone number you chose to activate it too.

If you purchased the phone together with the service contract, contact your phone service provider's customer support.

If you purchased the phone separately as a new device, contact the seller for a replacement.

If you purchased a second-hand phone, this phone was bound to a service contract and will work with the original SIM card only. The OTSKL acronym stands for "One Time Keypad Subsidy Lock" and as the name says, it can be used one time only to register to a network.

For reference, see US Pat. 6314283:
"A cellular phone subsidy lock which ensures that a cellular phone, sold to an end-user at a price subsidized by a cellular carrier, is activated only on the subsidizing carrier's network, and not on a competitor's network. A secure carrier code, specific to and known by the subsidizing carrier, is programed into the cellular phone by the phone manufacturer. The phone is programmed and shipped by the manufacturer in a locked condition, which prevents programming of the NAM (Number Assignment Module) of the cellular phone without first entering either a valid unlock code or a valid remove lock code. At the time of phone activation and programming of the NAM, the phone's ESN (Electronic Serial Number) is entered into the carrier computer system, which utilizes the ESN and carrier code to execute a subsidy lock algorithm which outputs an unlock code and a remove lock code. At the carrier's choice, either code is given to the end user to be entered into the phone. The phone then executes the same subsidy lock algorithm, using the carrier code programmed at the time of manufacture, and it's own ESN, to calculate the unlock code and the remove lock code. If the code entered by the user matches the unlock code, NAM programming is allowed to proceed only once, and if the entered number matches the remove lock code, the phone removes the subsidy lock completely."

I think the phone it self should be unlock but If you want to use the phone with a different carrier call AT&T at 800-331-0500 and they should be able to provide you with an unlock code for free. (all you need is the ESN number).

You'll first need to obtain the IMEI or ESN (both basically mean serial number, but depending upon who the carrier is, it will have a different name). You can do this by removing the battery and looking at the sticker located on the back of the phone. There will be several numbers on this sticker, but only one labeled an IMEI or ESN.

Next, contact the provider/carrier the phone is locked to currently. You'll see their name or logo on the phone somewhere. Some common ones are AT&T, Verizon, and T-Mobile. Provide them the IMEI or ESN and they will provide you with the unlocking code as well as HOW to put in the code since all phones are different.

Hope this helps! :)

Then contact the provider/carrier the phone is locked to currently (AT&T, Verizon, etc). Provide them with the IMEI or ESN and they will provide you with not only the code, but also with HOW to put in the code since some phones are more difficult than others.

Now the process is complete, and the phone is now ready to be used with a different company.

Thank you for using FixYa!

Do have a nice day and please remember to rate this solution.

Best regards,

That depends upon carrier. You must first register the SmartCard (T-Mobile/AT&T etc) or the ESN with the carrier you wish to use. Then for Verizon or AT&T (and some other carriers) after the card/esn is registered place a call to *228.

If the phone is ESN locked to a specific carrier and you wish to utilize a different carrier you must unlock the ESN prior to attempting to register it with the carrier of your choice. You must also correctly configure network type, protocol, etc, with information obtained from that carrier prior to activation.

Not all phones can be swapped from company to company in this fashion as some have company specific hardware at time of manufacture.

usually the unlock code for LG phones is 00000
try it maybe it helps
