Unlock Sony Xperia U ST25I Handset!

In case your Xperia U ST25I doesn't ask for the code and there is no designated field to enter it, please DON'T PLACE ANY ORDER, contact us first for support.

Looking to get your Xperia U unlocked without hassle? Whilst you could go straight to your mobile network operator, it may be costly and you’ll end up spending much too long talking to customer service as they convince you to stay on the network. Luckily SafeUnlockCode has an online unlocking service that’s simple to use, it’s quick, and 100% guaranteed to work!

You’ll be able to get your Xperia U in just one minute once you’ve received your unlock code!

If you’re looking to unlock a different handset instead, you’ll be happy to know we have a large phone list you can look through.

Being unlocked is great! Once you’re unlocked, your Xperia U will be usable with any GSM SIM network worldwide! This includes networks like Vodafone, Sprint, AT&T, Rogers, Bell, Fido, Verizon, Orange, Three 3, and a lot more!

Important Guidelines!

To get unlocked you’ll just need to follow the guideline below! Here is a summary of what you’ll need.

  • IMEI number - This is a 15 or 16 digit code that can be found by dialing *#06# 
  • Network - This will be the network your Xperia U is locked to.
  • Country - This will be the country you purchased your Xperia U from.

Next, you’ll need to check and make sure your Xperia U isn’t hardlocked. Being hardlocked means you have no unlock attempts remaining and will not be able to get unlocked through our service. To find out if you’re hardlocked, first enter a SIM card that uses a different network to the one you are locked to and then make sure your Xperia U is switched on.

Next, click onto the emergency calls screen and then *#*#7378423#*#*. (alternatively you could press the following- Menu Back Back Menu Back Menu Menu Back.)

A message should now appear that looks like the following:
- Network 10
- Network Subset 10
- Service Provider 10
- Corporate 10
- Sim 0

If you have a number ‘0’ next to network, this means you have run out of unlock attempts and cannot get unlocked through us! Any other number simply defines how many unlock attempts you do have left.

How to Unlock Sony Xperia U ST25I Phone - Tutorial!

Now for the fun part!

First, send us your Xperia U’s IMEI number, it’s country, it’s network, and an active email address so we can send you an unlock code!

After that, have a check at the pricing and the availability as well. Then proceed to payment and make an order.

Once you’ve made an order, you’ll have to wait a while for us to get you an unlock code, but once you have your unlock code, enter the same SIM card you did beforehand and then wait for a screen to display. On this screen there should be an ‘enter unlock code’ enter field- enter the unlock code we sent you here and your Xperia U will be unlocked!

Having some issues with this process? Please contact us.
