SOURCE: insert correct sim card

Un-Clocked is temporary, allows free txt and calls for a few minutes.
Un-Locked from a network is what will allow you to use any sim card on your phone.

SOURCE: Sony Ericsson - phone lock code

Hi Cheryl!!!

I think i may have a solution for u. It sounds like a Phonelock code...all Cellphones have one. Its in the software for the phones. Its a little like a SIM code. U could try with entering the code 0000. That could work!!

Good Luck :-)

SOURCE: says insert sim card when there is one in it

"Insert SIM" message is normally displayed on phones when a SIM card is not inserted on power-on or it does not detect the SIM card inserted.

Likely Causes:

  1. No SIM card inserted or inserted SIM card is damaged
  2. Inserted SIM card not positioned well in such a way as to make contact with the corresponding contact bridges on phone.
  3. Phone locked to a specific network and can only work on other networks when the firmware version is "flashed", that is completely changed to an unlocked version.
  4. The phone might be faulty (try with another good SIM, if you still get thesame message and its not one of the above reasons... it might be a transciever problem or the phone's SIM card slot's pins might be defective).
cheers.

How to reprogram my sony ericsson k800i


Instructions

Obtain the unlock code for your K800i if the phone is locked. You can get the code from an unlocking service, or from the carrier that originally sold the phone.

Turn off the K800i and turn the phone over.

Remove the battery cover by sliding it toward the bottom of the phone. Lift the battery from the bottom and set the battery cover and battery aside.

Remove the old SIM card by sliding it out from under the metal clip. If you have an unlocked K800i, all you need to do is insert the SIM card from your new carrier. Otherwise, leave the SIM out and reinstall the battery and battery cover.

Turn the phone on and wait for it to boot up.

Press left on the navigation pad and press "*" twice, then press the left arrow again. The phone will display "Personalize with MNC2."

Type the unlock code and wait for the phone to reboot.

Turn the phone off and insert the new SIM card.

Hi.... i am using nokia 2690 how to lock the cell with password ???? plz guide me sir :(


Select Menu > Settings > Security and from the following options:
  • PIN code request or UPIN code request-to set the phone to ask for your PIN or UPIN code every time the phone is switched on. Some SIM cards do not allow the code request to be turned off.
  • Security level > Phone-to set the phone to ask for the security code whenever a new SIM card is inserted into the phone. If you select Memory, the phone asks for the security code when the SIM card memory is selected, and you want to change the memory in use.
  • Access codes-to change the security code (default code is 12345), PIN code, PIN2 code, or restriction password.

Sms out going problem.Take out the sim and use another mobile have no problem.


When you place a new or a existing SIM card from another phone provider into your mobile phone and it asks for a Security code then :-
This phone is locked to the original mobile phone provider. You need to contact this mobile provider to ask for the unlock code (security code) for this phone. You need to provide proof of ownership etc and the phone's unique IMEI number which is located inside the phone under the battery. They use this number to generate the unlock code for your phone.
They should provide you with instructions on how to enter this code into the phone.
Once you unlock the phone, then you can insert a new SIM card in this phone or sign up with another phone provider using this phone.

You could ring the phone provider and ask for the unlock security code because you are going overseas and wish to use your phone with a prepaid SIM card from another country. This maybe a free service.
The other way to get your phone unlock is to use a phone unlocking company on the Internet, they usually charge a couple of Dollars for their services. Use Google and search for "Security unlocking code”.

Restriction code for nokia 6300 locked in fido


Hi, 
The security code, if you did not change it is mentioned in the user manual book. For Nokia cell phone, it is usually 12345.
This is the code the phone asked you to enter when you change your SIM card.
The code only asked once for every SIM card, unless you reset your phone. To disable this code, enter menu settings, Security, Security Level, change it to memory or none. To change this you need the security code.
