  1. Input a non accepted SIM card
  2. Phone will prompt you for a code
  3. Enter code provided by us

OR

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!

  1. For the unlocking of a locked  Sony Ericsson no sim card is required.
  2. Turn on the handset.  Display will indicate “Insert SIM.”
  3. Press the left Arrow (<) button.
  4. Press the star (*) button twice.
  5. Press the left Arrow (<) button again.
  6. You will briefly see one of the following messages listed on devices display: “Personalized with MNC2” or “Personalized with MNC3”.
  7. Wait approximately three seconds.
  8. The display will indicate “Network” and a picture of a closed lock.
  9. Press Select.
  10. The display will indicate “Unlock (Net) 5” and “NCK:”
  11. Enter the 16 digit NLCK4U code (unlock code we provided you) and press okay.
  12. The handset will display “Network unlocked” and the display “Insert SIM” appears.
  13. The handset is successfully unlocked.

 

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

Note: Please make sure the phone have SIMLOCK when pressing these keys to get into the Service menu.
OR
 
press *#*#7378423#*#* and access the service menu
You will see a menu:

EX:

[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.

 

OR
 
The best way to tell if your phone is unlocked, is just input a non accepted simcard, and see if you can make a call with it.

 

———- Trouble Shooting ———-

“Code Error” or “Sim Network Unlock Unsuccessful” What do I do?* Please check your IMEI number by pressing *#06#, this is the most common reason the code doesn’t work.  If the first 15 digits which appear is different from the 15 digit IMEI number provided above, please reply directly to this E-mail.

 

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.
