How to Enter Unlock Codes on Sony Ericsson Cell Phones (most models):
If your phone has a "JOGDIAL" (for example SonyEricsson K700i), then you must press the "down arrow" instead of the "left arrow" for step 3 & 5. By "Down Arrow" I mean directing the Jogdial down!
If Phone says, "Code Accepted" or "Network Unlock Successful" or "Not Yet Personalized" your phone is fully Unlocked
*If you are not receiving any signal after unlocking, make sure your wireless connections are turned on after unlocking the phone. Also pull the battery and restart phone.
How do I know my Phone's Network is Fully Unlocked?
Checking Lock Status for Xperia Models Only
With a Non accepted simcard start up the phone. When the screen says "emergency calls"
1. Start up the phone and press the Menu key ( ) and Back key ( ) as follows:
2. Pressing Key Sequences: Menu Back Back Menu Back Menu Menu Back
[X] Network 10 <== This means you have 10 attempts to enter the code, and then network is still locked.
[ ] Network Subset 10
[ ] Service Provider 10
[ ] Corporate 10
[ ] Sim 0
If it shows [ ] rather than [x] for all the boxes above, it means your phone is fully unlocked.
If it shows [X] Network 0, it means your phone is hardlocked, 0 attempts to enter the code. You can only unlock your phone via Xperia Unlock Software in this case. We do not refund 0 attempt unlocks.
I can make Calls and Text but I'm not getting Internet Service.
In this case you will need to adjust what's called the APN settings. The APN settings vary depending on the service provider you are trying to use. Please contact your service provider and they can assist you setting this up. There is no separate unlock for data or internet. If you can call or text, your phone's network is fully unlocked.
My Phone is asking for the "PUK" or "Security Pin" or "Password"
If your phone is asking for one of the above, it is the Simcard personal password or phone security password NOT the Network Lock which we provide for you. You can contact your service provider for this. Once you bypass this, you can use the Network Unlock Code provided by us.
My Phone seems to be unlocked but I'm not getting any signal
First of all, we do request you contact the service provider to make sure after unlocking your device, your unlocked phone will be compatible on their network. Not all GSM phones are compatible with any Network after unlocking it. The unlocked phone must be able to support the Network's Frequency. If you are unsure of this, please contact them regading this.
After unlocking your phone, please pull the battery for a couple minutes and then restart the device. It may take a few minutes for your phone to pick up the new signal. Also go to your Network settings on your phone, and make sure the device can detect the signal from the simcard you are trying use.
