Or get Orange Business £45/month for 1,100 minutes of euro calls inc mobiles.

Roaming charges apply, but if you're a UK based Euro-business then this is the best price plan I know of. You can phone all your contacts for only £45/month (£40+VAT).

Only available to business accounts, you can change a peronal account to business with a small amount of jiggery pokery.

While in USA just buy one of the $30 fliphones on the Net10 service. I couldn't find a cheaper deal. 5c a minute local, 10c for national and only 15c for international.

Net10 - 15c to phone UK from USA on a mobile. For business travellers it makes sense financially.

I am surprised that Vodafone made a US/Canada region but not a Singapore and Australia region, the call costs are around the same.

For inter union calls the price is more reasonable because the commission has set the standard, for everywhere else vodaphone is still indulging in highway robbery. This is what they are selling as an improvement?
