my sony ericsson k510i is locked to orange but tells me invalid sim even with an orange sim card in, why?

W200i CID53 mobile...you will need to try online at topsony.com or take the phone to a mobile center and have it unlock there.

i know only unlocking..Unlocking your phone will enable you to use a sim card from any mobile network, in any country. Using the serial number of your phone, sony provide a remote unlock code to lift any restrictions currently placed on your handset by your current network provider. You will get a true Manufacturer's code directly from Sony Ericsson factory. This genuine factory unlocking code is compatible with any Sony Ericsson phone..

You can use a Orange PAYG sim in there. However, sometimes orange does not lock their phones

go to your nearest service center and unlock your fone....u need the box and software to open your fone.....sorry m8
