Sony Ericsson makes a wide range of cell phones and smartphones, and when you consider the many more phones no longer being manufactured but still in use, the range grows greater still. Many of these phones are designed to work on GSM networks around the world, but are sold with SIM locks that tie the phone to the specific carrier who sold it. To make the phone world unlocked, you need to enter a specific mobile phone unlock code that is uniquely configured for your phone.

The main reason to get a phone unlocked is because you want to use it elsewhere in the world than your local carrier’s coverage. An unlocked phone is called world unlocked because once it’s unlocked, it can be used on any GSM network anywhere in the world. Of course, you will still need to have a SIM card that is associated with the GSM network that you choose to use, but there are a variety of international SIM cards that can be used with multiple networks, rather than forcing you to use a single network.

No matter what model of Sony Ericsson phone you have, you can perform a cell phone unlock process in just a few minutes. The first thing you need is your IMEI number. To get the IMEI number from your phone, dial the characters *#06# as if you were placing a call.

Your current carrier may be willing to give you the mobile phone unlock code for free. Most of them are pretty good about helping out their customers who want a cell phone unlock so that they can use their phones while travelling internationally. After all, if you’re still under contract, and will be paying them regardless of how many minutes you talk or how much data you download, it’s in their best interests to let you use another carrier for part of the month.

If you can’t get the code from your current carrier, you can always buy the code from an online vendor. There are many of these, offering various levels of customer service and response times. If you want videos demonstrating how to enter the code to get a phone unlocked you’ll pay more than a service that emails you the unlock code and nothing else.

The common method of unlocking a Sony Ericsson phone follows these steps:

1. Power off your phone.

2. Take out your existing SIM card. Put in an international SIM card.

3. Power on your phone.

4. The phone will request the SIM network unlock PIN.

5. Enter the specific code you received.

Once the code has been accepted, your phone is unlocked. You can then use it with the GSM network of your choice.
