Hi! I accidently locked my Sony Ericsson z550i with some kind of a password. The only thing I know is that when i turn my mobile on it says i have to enter some kind of password ( I don`t even know a...


You can get the unlock code by contacting your current service provider customer care department. If your phone is locked you can use any of your friends phone to make this call. The service provider will then provide you the unlocking codes. Everything is done for free of cost and you are not going to be charged for this process.

Another alternative is, you can take the phone to any authorize phone service center to help unlock the phone, 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..

Phone locked


Okay, well i do not know much about these phones but i will give you a few options that work for verizon.
You can try the standard "0000" also there is the possibility of it being the last four digits of your cell phone number. and if that doesnt work you can call your service provider and they can reset the code.

How to key pad lock sony ericsson z550i?


Dear Freinds,

I have Z550i by mistake it droped in water for 10 minutes. I make it ON after soaking for 4 -5 hours. Now it is goiving humming sound only when we recieve calls (during active network link with other person) from other side or when we dial someone. In simple on condition there is no humming sound. Also it is discharging soon. MP3 songs and radio is working fine. When I put it in charging it shows that your USB port is active and reday to data transfer. I am unable to understand what is the problem.

Please advise a best solution .....

Thanks

Prakash
