Sony Ericsson w850i

    Hey all, i got a sony ericsson w850i which constantly displays "Inactive SIM" instead of "o2 - UK" like it should do. Why is it doing this? Is there any way to prevent this? Thanks


    Is it new? Sim card registered?

    The phones not new, yep all four sim's i have tried are registered


    also try another sim from another network

    As far as my phone knowledge is comprehended, your phone is locked to one netowork. You will be required to go to your nearest phone shop and say you want this unlocked to all networks. That should do the trick!:thumbsup:


    blocked?also try another sim from another network

    usually inactive sim means the phone is barred/blocked.

    although i tried an old expired tmobile sim in my old k700i and it said inactive sim
