How does an unlock code work?

Unlocking your phone couldn't be easier! SIMLOCK unlock codes work like this: you make an order here on our site, giving us your phone's unique IMEI number in the process. We work our magic and then deliver the numerical unlock code to you via email, along with instructions to enter it. Enter that code into your phone and you are unlocked for use on any network, anywhere in the world, permanently.

Use the phone selection form above for pricing and availability details.

How does Sony Ericsson debranding work?

Debranding means to flash generic firmware (as opposed to provider firmware) to your phone. This process takes place via our software, allowing you to simply connect your phone, select your service and flash the phone with the firmware of your choice. If you're tired of the logos, branded apps and restrictions placed on your phone, then debranding is for you!

Please visit our Sony Ericsson flashing/debranding tutorial for more detailed information on the process including instructions covering everything from purchase to completed flash.

How does Sony Ericsson unlocking work?

We provide SIM unlocking services for most types of phone via an unlock code but our software gives you the ability to instantly unlock nearly any Sony Ericsson phone at a fraction of the cost and with none of the wait of a code! Our software allows you to unlock your Sony Ericsson phone in mere minutes, from old favorites like the K850 to cutting edge Android devices like the Xperia Arc S.

Please visit our Sony Ericsson SIM unlocking tutorial for more detailed information on the process including instructions covering everything from purchase to completed unlock.

How long do I wait after purchasing?

If you purchased a license to perform an instant process via our software, your account has already been created and an email with instructions to proceed is waiting in your email inbox! If you purchased an unlock code then the time you must wait for delivery depends on the type of phone you have. Please visit your phone's page on our site for full details.
