SOURCE: keeps saying usim locked
hello there....well its quite simple...there is nothing wrong with your phone ...its your SIM... if it is asking for a PUK (Personal Unblocking Key) code...call your subscriber and ask them for PUK code,entering this code will reset your sim
if u keep entering wrong your sim will be damaged so call them
If the error message is saying sim damaged call them and ask for a "sim replacement" you will get a new sim while you will retain the same number ,however you will lose the phone numbers and other data stored in sim,this can be free but it depends on the company and how 'customer friendly they are
Hope this helps

SOURCE: I need unlock codes for LG gb102
When you place a new or a existing SIM card from another phone provider into your mobile phone and it asks for a Security code then :-
This phone is locked to the original mobile phone provider. You need to contact this mobile provider to ask for the unlock code (security code) for this phone. You need to provide proof of ownership etc and the phone's unique IMEI number which is located inside the phone under the battery. They use this number to generate the unlock code for your phone.
They should provide you with instructions on how to enter this code into the phone.
Once you unlock the phone, then you can insert a new SIM card in this phone or sign up with another phone provider using this phone.
You could ring the phone provider and ask for the unlock security code because you are going overseas and wish to use your phone with a prepaid SIM card from another country. This maybe a free service.
The other way to get your phone unlock is to use a phone unlocking company on the Internet, they usually charge a couple of Dollars for their services. Use Google and search for "Security unlocking code” companies in your area.
