Help New sim, same phone, no signal

[awhiteheaduk]

Okay, so a week ago I lost my phone - an HTC Desire - and having given up searching, cancelled the SIM and picked up a replacement from a T-Mobile shop.

I then put this temporarily in a Blackberry (I know, stupid) until I could find a more cheap and permanent, preferably Android, phone for the remainder of my contract However, my old phone then turned up, so I put the new SIM in the old phone, and somehow I have no mobile signal at all - it's not locked because it doesn't ask me for a code or anything. It says "emergency calls only" but even they don't work. I can however use data on the browser, over 3G (even though the icon doesn't come up.)

I tried putting the SIM back in the Blackberry it was previously working in and that no longer picks up the signal.

Current theory is that the SIM was damaged when I moved it across, is this likely? What on earth is going on?

Swapping SIMs is part of the spec, so that shouldn't cause a problem. But if the SIM doesn't work in 2 phones that suggests that the problem is with the SIM. If a different SIM works in the Desire that would prove the problem was not the phone. But I'd try a replacement SIM.

Was hoping that wouldn't be the solution, but does make most sense. *sigh* Thanks!

I had my SIM never in a BlackBerry, but the same SIM in a Nokia, a Motorola, a Sony-Ericsson and several HTC Androids.
Never had a problem with the SIM
