Re: security code

Go to Settings > Security > Phone protection > Protection.
Turn this on.
Enter a code you will remember easily, something which may mean something to you, like a sibling's birthday or memorable year. It must be four digits long.

P.S. for your security, I advise you do not post your private e-mail address anywhere like forums, it can pose a security risk as everyone can see it. (Friendly advice)

Security code


The default code for most phones is "000000" or "0000" or "1234" or "123456' or 12345 or 00000. One of these codes is always a standard master code in most cell phone models.

Hope this helps,

Networks lock their phones to protect their revenues, they subsidise the handsets on their contracts and as such they want to maximise the return they get from the contract you take out with them. In an ideal world the network would give you your K800i unlock code on completion of your contract but quite often they make you pay to get your Sony Ericsson phone unlocked.

Dear, please help me i have sony erricssob K530i mobile, i am unable to apply security code to lock the phone, i dont know about default security code kindly help me if u know the security code for this...

Normally, the default code for Se is 0000 that is four Zeros. but if you are not the first user, then it may have most probably been changed. The only way would be to use a DCU60 usb cable and read the codes from the phone directly using this program called setool2 lite. just google you will find it. here is screen-shot.1cf6102.jpg

Down load drivers for P900 from the net


Unfortunately the PC Suite that is compatible with the P900 is not compatible with Vista. There is no solution unless SE decides to release a Vista compatible version. Sorry...

What 'bout other phones ? There could be a Tower faillure near your area. Please check out whether other phones work not. Otherwise there might be a network faillure in your cell phone or you might need to replace your antena. If possible open up your mobile carefully and refix everything, it should work.
