Phone lock code

Dear Sirs,

Please advise.My k550i asked me to insert sim, which I did.Then it asked me for the phone lock code. I thought that the AUD$30.00 I paid was to get it off the previous network. I'm now totally confused.

Keep saying insert SIM card


You are trying to use a SIM from another Network or Handset but your phone is LOCKED to your old network and/or to a specific SIM card and number: this is why it is asking you for the unlock code to remove the restriction. It you are no longer under contract or obligations (such as minimum total recharge amounts for apre-paid handsets), then you could try to request the unlock code from the original service provider of your handset.
As for asking to insert SIM card, make sure that the SIM is correctly and securely inserted in your handset SIM holder. Also check that the SIM is still functional by inserting it in another handset: SIM card can be permanently and physically disabled if you attempt to enter too many consecutive invalid codes (usually around 10).
Hope it helps and good luck!

Unloock sony erricson k550i so i can use any sim card in Ireland


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”.

What kind of code is it asking for?

If it ask for a PIN code then it means it's asking for the password/code you have entered on your SIM card. If it asks for Security code then that means it's the password/code for the phone.

Entering three invalid PIN codes on your phone then your PIN may be locked and you can only unlcok it by entering the PUK code on your SIM. PUK code is available on the sim card pack. Once it's ented, you have the option of changing your PIN code. Just be sure to remember your PIN code so the same incident won't happen again. If it ask for security code, enter the code you have for the phone but if you don't remember setting a security code, then you may try the default security code of Sony Ericsson phones which is 00000.
