Hello mate, You can get samsung sgh unlock code and LG KF390 unlock code from telstra provider but you must pay some charges and wait for a couple of weeks for that unlock code. Another shortcut you can purchase reliable samsung unlock code at third parties sites on internet.

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 Telstra). 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.
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.

Unfortunately, you would have to request unlock code from service provider to unlock phone.

Hi there, I can see why you would want to keep that phone, sharp looking phone.. well looking at the Telsra web site I found this
Question: Will my mobile work with Telstra's Next G™ Network?
Answer: Please check your mobile's user guide or manufacturer's website. Look in the "tech specs" for your mobile, and see if 3G support at 850mhz is listed. This means your mobile is compatible with Next G™.
If your mobile is compatible with Next G™, we can send you a new SIM card once you have signed up to a Next G™ mobile plan, so you can begin using the additional services available on Next G™.
If you're still unsure if

I found the phones specs
Network vx9900 env verizon
Technology CDMA Frequencies/Bands 850, 1900 Data It does not look like that phone will work with the Telstra service. To make sure you should contact Telstra ask for a tech. (any one else just may try selling you another phone) Ask for tech...Don't call from your cell they may have you take bat. off to read #'s on back of phone.

the only way to unlock a phone is to call the original company andtell them u want it unlocked for international travel. using it for another co. is illegal though so be carefull!
