SOURCE: sim card not working sim works in other phone

The first thing you can do if you think there is aproblem with the phone settings is that :
Go into network setings of the phone and choose MANUAL in the Network selection. Then you can search for the Lebara network manually and select it, if it works.
Or if it doesnt work, then the phone probably might have been locked. Just check it once, using any other network simcards it your phone. If it is locked, you can easily get it unlocked in your local market.

Tip & How-To about Cell Phones
Your phone is asking for a PUK code?

Is your phone asking for a PUK code. PUK = Personal Unlocking Key. Personal Unblocking Key, or PIN Unblocking Key.

This can only come from your cellphone carrier and usually the company that still owns the phone under the agreement. Sometimes it is because you have put another SIM card in it, and they own the phone and need you to use them as carrier to get the price of the phone back, or you are in default of payment, or on a Pay as You Go plan, it is over expired. I can also happen if you have entered the unlock code wrongly three times. This often happens when a phone is stolen or lost and has been found by or sold to someone else who then try and use the phone. Wikipedia A personal unblocking code (PUC), also known as a PIN unlock key (PUK), is used in 3GPP mobile phones to reset a personal identification number (PIN) that has been lost or forgotten.
Most mobile telephones offer the feature of PIN protection. After switching on the phone, if the PIN security function is active, the user is requested to enter a 4-8 digit PIN enabling the phone's non-emergency calling functions. If the wrong PIN is typed in more than three times, either the SIM card, the device, or both become locked. They can be returned to their original unlocked state by entering a PUC, provided by the service operator after verification. If the wrong PUC is entered ten times in a row, the device will become permanently blocked and unrecoverable, requiring a new SIM card. Cellular phone users are therefore advised by most providers to keep their PUC written down in a safe place separate from the device.
The PUC (PUK) is a SIM-specific code assigned and provided by the service provider.
Once you enter the PUK code, you must set a PIN. The PUK and PUK2 are used to unlock the PIN and PIN2 codes respectively if your SIM card is blocked
From Bell
The PIN unblocking key (PUK; sometimes called personal unlocking key) is a master security code for unblocking and resetting the personal identification number (PIN) for your SIM card. For added security, the PUK is unique to your SIM card. If your PIN code is active and you enter it incorrectly three times, your SIM card will be blocked. You won't be able to use your phone, except for emergency calls. You must enter your PUK into your phone to unblock the SIM card. If your SIM card becomes blocked, Contact us to get your PUK.
You may be able to do it from the website or your cellular provider. This is from Orange - T-Mobile in the UK.
Your phone can become blocked in a number of ways - one of them is if you enter your SIM card PIN number incorrectly three times in a row. To unblock your SIM card, you will need to use something called a PUK (Personal Unblocking Key).
Remember that unblocking is different to unlocking. Read more information on unlocking your device.

  2. Select Help & Support from the main menu options on your account homepage.
  3. Select Get your PUK code.
  4. Then select Get PUK1 code.
  5. Once you have your PUK code, enter this into your phone to unblock your SIM.
Please enter your PUK code carefully - if you enter the wrong PUK code 10 times, you will permanently block your SIM card and we'll need to send you a new one. 1826865-en.jpg?2.0

Couldn't register service provider. Display shows ''LTD. SERVICE''


Its purely network problem. Dont try again and again with the same solutions. Switch off the mobile for some time, remove battery, and sim card, and put them again after some time and switch it on. In samsung, while switching on, it will show the service providers name in the start up screen. if it shows, then it should work. If it doesnt work, some problem with the sim card. try to replace it. or otherwise general operation in selecting the network shud help.

My Samsung SGH-d807 is locked, and i have tried to unlock it 5 times after which it says a message that permanently locked to cingular network.


1. If you have changed your phone password, change your password back to the default 8 zeros (00000000).
1a. NOTE: Go to SETTINGS, SECURITY, then SIM LOCK and disable this before proceeding.
2. Put a SIM card that is from a network other than the one your phone is locked to
3. When Incorrect SIM (I got invalid card and there was a sim card graphic spinning) error comes up, type *#9998*3323#.
4. White screen will appear with an exit option. Press the right softkey. (you may have to push the down key to get a menu)
5. From the menu that appears, select the Malloc Fail option. This will reboot the phone and the normal service screens will appear.
6. Type *0141# and then press the green call key. "Personalization" or "Personalized" will appear.
7. Turn off your phone and put the original SIM back in.
8. Turn on your phone. You will receive a prompt to enter a password.
9. Type 8 zeros (00000000) (This is because the SIM LOCK Mentioned earlier gets switched back on)
10. Completed. You have now unlocked your phone.

this may be what you allready tried, but it worked for me, good luck
