TROUBLESHOOTING

Notice: This section assumes that you have the unfreeze code we sent you. If you have purchased a carrier unlock code, you will not be able to unfreeze your phone.

Step 1: Determining the lock level of your Samsung

If you have ordered unlock codes from our website, 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 an alternative lock level such as SCK or SPCK.

It is best to be 100% sure which lock level is present on your phone. You can do this by following these instructions:

1. Make sure a SIM card is inserted in your phone. The SIM card must be from the network your phone is locked to. (For example, if you are locked to Orange, insert an Orange SIM card.)
2. Once connected, dial *#7465625#.
3. 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 as 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.

If you see the SP lock value as ON, you will need the SPCK code.

The unfreeze code should only be needed if:

(a) You accidentally freeze your handset by entering too many incorrect codes or no following our unlock instructions accurately.
(b) Your phone 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 phone and thus the correct code required for input, you may continue.

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

Step 3: General Troubleshooting

If your phone freezes for any reason and displays a “Phone Freeze” or “Return for Service” message, you will need to use the unfreeze code that was issued with your unlock codes.

Below is a list of instructions for entering the unfreeze code into different models of Samsung devices.

Choose the 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 is provided free of charge.

Reasons for Freezing

(a) Inputting the unfreeze code rather than the unlock code into your phone.
(b) Following the incorrect input procedure for your phone. These must be followed 100% correctly.
(c) Unaccepted SIM cards. If your phone works when an accepted SIM card is inserted, this is the reason.

Unfreezing Your Phone

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