Google Sync when using different SIM

[Norwegianpiglet]

I go to Norway from time to time and have a Norwegian PAYG SIM that I use when I am there. Using it with my old Hero was no problem, so am hoping it won't be with teh Desire either. The only thing was that google would not sync, and login details didn't seem to work, coming up as Sync error . FWIW it does the same when I have put different SIMs in teh Desire here in the UK too.

Anyone know what this is due to and if it can be sorted? Is it a googlemail/gmail incompatibility issue?

Would like to be able to sync contacts and calendar still while out there.
