Search the internet for LG Shine unlock codes based on your phones IMEI number. A local phone shop may also do this for you.

To have the t-zone to work and have MMS, do the following:
Menu->Settings->Connection-> Network Profiles then click "New"
* leave blank *
* leave blank *
then click save. This will allow the t-zone to work on your browser. Next, to set up your MMS settings, do the following:
Menu->Messaging->Message Settings->Multimedia Message->Message Center->Options->New
TCP without Proxy
then save it, and activate that profile. If all goes well, those should be the correct setting for tmobile tzone and mms on an unlocked AT&T CU720 Shine as of October 18, 2008

On the AT&T Network, to unlock the LG Shine or CU720, it’s pretty simple:
To obtain the IMEI number, type *#06# on your device. This is a 17 digit number and it is not the same as the unlock code, this is the IMEI number to give to AT&T Technical Support in exchange for the 16 digit Subsidy Unlock Code.
to get the (16 digits code) call att and tell them you are traveling overseas, it may take two calls.
,but they should give it to you the (16 digits code)
Insert non ATT SIM
Showing 'Invalid Smart Chip'
This will take you to a screen saying you are about to unlock your phone. Do you want to proceed.
Select yes (left button)
Enter your 16digits code.
Enter your code again
Now the phone is unlocked
It requires 2 inputs of the unlock code.
If this helps solve your problem please give a fixya rating, all of them are really appreciated, sorry I cant personally tell you the code number, but ATT or your Service provider should, if all else fails, here's an online service.

The LG Shine will only save messages to the SIM card after the internal phone memory is full (150 messages). This all happens automatically, and as far as I can tell, there is no way to force the phone to choose. Also, note that the SIM card will only store 30 messages. You can select the options menu
