How to enter my Unlock Code on Samsung ?


  


If you have trouble to enter code and/or if code is not accepted on Samsung Android Phone like Samsung T959, then please try to make "Factory Reset" following the instructions below :

1 - Shut your Android Galaxy S down (Power off) or remove Battery.

2 - Now press Volume up, Home and Power together.

3 - If the Samsung Symbol is comming up leave the Home Button.

4 - Then there is a boot Menu

5 - Volume Up and Down to Navigate , Home to select the choosen option.

 

Our instructions are GLOBAL instructions for all unlocking services.

Instructions about unfreeze are meant for people who have purchased a FACTORY SAMSUNG GENUINE UNLOCK CODES service, which include UNFREEZE code. If you have purchased a carrier unlock code (from you network provider): this service does not include UNFREEZE code. If you have FREEZED your phone, the unlock network code won't help to unfreeze, only unfreeze code will reset freezed phones.

 

- Step 1: Determine the lock level of your Samsung -

 

If you have ordered unlock codes from our website, you will have been pleased to see that every possible unlock code has been emailed to you.

The unlock codes emailed to you will look something like this: Unfreeze: 12345678 NCK: 12345678 SCK: 12345678 SPCK: 12345678

Most networks only lock their Samsung handsets with the NCK lock enabled.

Therefore you should only need to use this code when following the input instructions (see step 2).

However some networks will have dual locks in place (whereby the NCK and another lock is enabled) or they may have just an alternative lock level such as SCK or SPCK.

 

It is best practice to be 100% sure which lock level is present on your handset, to do this follow these instructions:

Enter the following code into your handset while it is turned on and connected to its locked network.

By this we mean the connected to the network your handset is locked to (if you are locked to Orange, insert an Orange SIM card into your handset)

Once connected, enter this code: *#7465625#

A menu will be displayed that will resemble the following...

1. [xxx] Network lock 2. [xxx] Subset lock 3. [xxx] SP lock (xxx = Value ON or OFF)

If only the Network lock is displayed saying ON then you will only need to use the NCK code with the instructions below.

If you see the Subset lock value as ON then you will need the SCK code and if you see the SP lock value as ON you will need the SPCK code.

The unfreeze code we send you should only be needed if:

(a) You accidentally freeze your handset by entering too many incorrect codes or not following our unlock instructions accurately.

(b) Your handset displays the 'phone freeze' message whenever an alternative network SIM card is inserted into your phone prior to it being unlocked.

(c) You see the 'return for service' message.

Now you know the correct lock level of your handset and thus the correct code required for input, you may continue...

NB: If your handset does not accept the code to locate your lock level, simply move straight on to step 2 of this guide.

- Step 3: Trouble Shooting -

 

If your handset freezes for whatever reason and displays the 'Phone Freeze' or 'Return for Service' message then you will need to use the unfreeze code that was issued with your unlock codes.

Below you will see a list of instructions for entering the unfreeze code into different models of Samsung handsets.

Choose the handset instructions closest to your own model if it is not directly available. (i.e. if you have a Samsung i900, consider using the Samsung F480 unfreeze instructions).

 

NB: Unfreeze instructions are given as an added bonus to your unlock service.

This is not the service you purchased and therefore it is provided free of charge.

 

Reasons for "Phone Freeze"

1. Inputting the unfreeze code rather than the unlock code into your handset.

2. Following the incorrect input procedure for your handset (these must be followed 100% correctly).

3. Handset automatically displaying "Phone Freeze" when an unaccepted SIM card is inserted into the handset, however when the accepted SIM card is inserted, the handset works fine.

 

Unlocking the phone when in "Phone Freeze"

In order to unlock your handset when the phone is frozen, you need to have access to the handset keypad.

Please note the following information is not provided with any guarantee or warranty of success as the unfreeze codes we provide are issued free of charge as an added bonus with certain Samsung unlocking services.

 

Option 1 (usually used with keypad Samsungs - U900 etc)

While an unaccepted SIM card is inserted

Enter the unfreeze code

Hit OK (either the left soft key, or in the middle of the touch-field)

Your handset may or may not display an unfreeze message

Now enter your unlock code (see step 1 above to determine this)

The phone should now unlock

 

or

 

Option 2 (usually used with touch screen Samsungs - F480 etc)

With Original SIM card in handset

Enter #7465625*638*UNFREEZE CODE

Please note once again, these instructions for frozen handsets are used at the owners risk.

Unfreeze codes are supplied as a bonus for certain Samsung services and we make no warranty or guarantee of their success. If in doubt, our customers may wish to have their handset manually unfrozen by a local independent mobile phone specialist before returning to use the unlock code we provided which is 100% accurate for your handset.
