Samsung SGH-Z500 I have a Samsung SGH-Z500 that will not work when a sim card is put in it. All the buttons etc work okay when no sim card is ih the phone, but as soon as I put the sim card in the phone will power up okay but then everything freezes after the initial power up has finished. Does anyone have any ideas ?

Hi,



1. Turn off your phone, put in a SIM of a different provider.
2. At the wrong card message, type *#9998*3323#. A message will pop up telling you to press exit, so hit the right soft key. Choose number 7 (or 8 or 9 will work too,) Your phone will reboot and your SIM will work.
3. Type *0141# and then hit call. This will give you a message saying your phone is personalized.
4. Power down your phone and insert your SIM. Then power back up your phone.
5. At the SIM pass code prompt type 00000000, that is 8 zeroes. So that will totally UNLOCK your phone." Do not try this more than twice.
Another alternative is, you can take the phone to any authorize phone service center to help unlock the phone, this is not what you can do yourself, because to unlock your phone, you will need some kind of software, USB cable etc to unlock the phone, so you can also go a nearby phone service center to unlock the phone, but calling your network service provider is the best because they have the records of your phone and can easily help to unlock it. This are the two reliable means you can unlock your phone.

If your Samsung SGH-Z500 is locked Mobile means you cannot Use in MTN Network......
