Sony Ericsson
cell phones are often locked to a particular GSM service provider, particularly when you buy it on a contract with a service provider. To switch to a different service provider, you must unlock the phone first. Remote unlocking is perhaps the simplest method of unlocking your handheld device. Various code-generating websites let you purchase your phone's code for a fee. The fee depends on the SE model and the network it is locked to.
Instructions
1. Find out the IMEI number of your Sony Ericsson phone by dialing "*#06#" on the keypad. As soon as you dial this code, a 15-digit IMEI number will appear on the screen. Write it down somewhere because will need to unlock the phone using a code generator.
2. Go to a Sony Ericsson code-generator website, such as Unlock All Cellular, Unlocking or Cell Corner (see Resources).
3. Select your Sony Ericsson model from the list on the website or type it in the search box, then hit "Enter."
4. Select your network carrier from the drop-down list. After you select the carrier, the website will work out the price of the code and show it to you.
5. Type your IMEI number in the respective field. Also, provide your email address.
6. Enter your credit card details to purchase the code. The code, along with instructions, will reach you via email within a few days.
7. Enter the code into the phone as instructed by the website you purchased it from. For most Sony Ericsson phones, you must power the phone on using the SIM card to which it's locked. When you've done this, press the "Left" arrow key one time, followed by the "asterisk" (*) key twice.
Press the "Left" arrow key, then wait 4 seconds until you see "Network" on the screen with a picture of a closed padlock. When you see this image, press "Select." The display will read "Unlock (Net) 5" and "NCK." Enter the unlock code provided by the website. You will see the "Network Unlocked" message on the screen.
