Unlock Codes For Sony Ericsson Xperia X10 [guide]

The Xperia X10 is the high-end entry in Sony Ericsson’s popular series of Xperia smartphones, released in 2009. It was the first of the Xperia line to run the Android operating system, and features a full touchscreen with a virtual keyboard as well as an 8.1 megapixel camera.

So if the Xperia X10 is such a high-end phone, why can’t you connect to any GSM network out of the box? The fault isn’t with the phone it’s with the cell phone carriers. They don’t want people to get free or discounted phones from them and then use the phone with one of their competitors, so Sony Ericsson SIM locks the phone at their request. Without the matching unique codes to unlock unique phones, you can only use the phones with the carrier from which you purchased them.

The good news is that unlocking your phone is both simple and legal. Why unlock phones? So you can use other carriers. This is especially important if you’re travelling out of country, and want to be able to buy a local SIM card so you can use your phone with a local carrier. Unlocking the phone also raises its resale value.

Some people worry, why unlock phones if you could damage the phone? No worries. There is no risk to unlocking your phone using the unlock codes that are specific to unique phones, since what you’re really doing is restoring the phone to its factory settings. The phone will also remain unlocked even if Sony Ericsson rolls out new software to the phones, and your warranty remains in effect.

If you are a customer in good standing with your carrier, it is possible they will give you the code you need for free. Depending on the conditions of your contract with them, you may need to have owned the phone and used their service for a minimum number of months. Just tell them you’re travelling out of country and want to use your phone with a local carrier in your destination country. They may even unlock the phone for you if you visit their store.

If your carrier is no help with the unlock code for the phone, you will need to purchase the unlock codes from a vendor. You simply provide the vendor with the make and model of your cell phone, along with its IMEI number.

Once you receive the unlock code, simply follow these steps.

1. Power off your phone.

2. Remove your existing SIM card.

3. Power on your phone.

4. The phone will ask for the SIM network unlock code.

5. Simply enter the unlock code you were given.

That’s all there is to it! After successfully unlocking the phone, you will be able to use your Xperia X10 with any GSM carrier.
