Mobile to different network?

[Alchemy]

Hi all,

My mobile phone can't be used as I'm abroad at the moment. I would like to use a native sim card, but was wondering how I go about doing this. Would I be able to phone up the network in question and tell them to pause the 'service' without paying anything? The network is Orange.

Any help would be much appreciated.

Thanks very much, Vegeta.

Can anyone do me a huge favour and find Orange's number for this matter? The Internet is so slow here and my brother isn't cooperating on MSN. Is there a number that can be called that isn't an automated service? I would appreciate it very much.
