w580i update search

Dear Sony Ericsson users,

Just recently i decided to move to another operator: Vodafone instead of Hi (Yes, they're dutch operators.) So I bought this SIM for vodafone and tried it to work on my phone. When I turned my phone on, my new SIM didn't work so I was like: "Uhh??", so I figured I'd have to search for updates on my phone, so I did and all it said was this error:

"Device mgmt.
SonyEricsson
Communication
interrupted"

I tried it with my old SIM and still it wouldn't work, so it's nothing to do with the new SIM or the operator. Yes, my phone is SIM-lock free and no, I haven't tried calling the customer's service yet because they're closed right now and I'm out of credit and I need to send some quick messages. Please help if you feel like it.
The phone is a w580i Sony Ericsson.

Regards,

Rob.

u can use sony ericsson update service on there web site to update it but it will change the cid on the phone to 53 not god if u modur phone as most free tool wont work

Ah, so do you think that's the problem? Or is there anythere reason my SIM won't work?

Thanks for your response :)

It should work since you said you are already unlocked. I don't think you need to risk being updated to CID53 by using the Update Service. It might be a problem with the new SIM card. Maybe it is defective?
