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:
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.
Have you ever received a phone from a relative, friend or just upgraded to a new phone and don't have the time or patience to call into a call center for support with activating the device or updating the PRL (Preferred Roaming List)? We all know the hold times can be long, the representatives may not be as helpful as we would like them to be or of course the wrong line gets changed causing a previously working phone to stop working (we all love that). And of course a simple 5-10 minute call has now turned into a 30 minute call (as if you had no plans to go to dinner or watch some T.V.). Well here are steps you can follow to program, update your PRL or process an ESN change with your new or new to you VZW (Verizon Wireless) phone. If the device you acquired is brand new or new to you and the ESN (Electronic Serial Number) has not been changed on the MDN (your phone number) you simply need to power off the old phone and on the new phone dial *228 and select option 3 when prompted. This option processes the ESN change automatically, programs the number into the phone and updates the PRL.
If the ESN change has already been processed you simply need to dial *228 and select option 1 to program your phone.
Lastly if you just need to update the PRL then dial *228 and select option 2. The PRL (Preferred Roaming List) update will ensure your phone is roaming on the tower that provides the best signal, potentially enhancing your service.
That's it! You are now ready to use your new phone!
CDMA cell phones generally cannot be used on any other network than the one that the ESN is programmed to. For example, Cricket ESNs can only be used on cricket, Verizon ESNs, can only be used on verizon... It doesn't matter if you change the firmware or not, many other service providers will not accept another service provider's ESN.
