I had a locked Sony Ericsson and my network would not give me the unlock code for it. I tried on many occasions but was fobbed off. If you cannot get your unlock code from your network or have purchased a locked phone, and you cannot find your unlock code online, dont worry. Try visiting one of the professional phone unlocking companies, to get your phone unlocked quickly and easily. They will usually charge you a small fee but its worth it for peace of mind.Simply visit the site of your choice, and input your phone make and model, you will also be required to input your IMEI number, this can be found underneath the battery or by dialling #06# on most phones. This should make it appear on your cell phone screen. You will then get your unlock code emailed to you. I used a company call UnlockCode Source but most of the others unlocking companies can also unlock your phone. Try visiting a few of their sites and compare prices.
Unlock Codes are available for the following phones: Nokia, Sony Ericsson, HTC, LG, Motorolla, Samsung, Panasonic, Toshiba, SAGEM, Sanyo, Sharp, Phillips, Ericsson, PalmOne, UTStarcom, Cect, Cosun, Fastcom. Legend, CTE and many more....
