Samsung Sgh A157 Network Unlock Code
Kym Wash
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.
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 2 : Input Instructions
1 - Switch ON your phone with an unaccepted SIM Card,
2 - The Phone will then ask for the Code or Password
3 - You can now enter the Unlock Code we sent to you.
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"
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
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.
If your Samsung device is locked, you will need to first figure out if the lock is carried locked or if it is simply a password lock. If your device is carrier locked, your new sim card will not work from a different carrier. You will often be asked to enter a Network Code or Sim Network Unlock Pin. If it is a password lock, you will locked out of the device at the lock screen or pattern lock screen.
Carrier locks are restrictions placed by mobile carriers to limit the use of your phone to their network. This is often done to ensure that contractual obligations, such as payment plans or service agreements, are fulfilled.
There are many benefits of unlocking your phone including resale value. Unlocked phones have a higher resale value since they can be used on any network. You also gain the flexibility to choose the carrier of your choice. Unlocking your phone gives you the freedom to choose or switch carriers based on your needs without needing a new device. Additionally, while travelling you have the ability to save on roaming costs by purchasing a local sim card. An unlocked phone can be used with local SIM cards while traveling internationally, avoiding expensive roaming charges.
Disclaimer: Your device must automatically prompt for an unlock code after restarting with a different SIM card. If your device does not ask you for an unlock code, then you do not need our services and you will not be refunded if still ordered. If you are uncertain then please contact us first before purchasing!
A: The unlock code for Samsung is usually an 8 or 16 digit sim network unlock pin. You can either get it from your carrier, or you can use services such as Cellunlocker.net to get the official Samsung Unlock code.
