You could get your own VoIP number and forward it to your mobile number.

voip.ms has excellent rates to most mobiles (you should look up the specific rate to this mobile number) and les.net isn't too bad to some but is high to others.

Expect to pay about $1 for setup and $1 a month plus 1.5 cents a minute for inbound calls, plus the cost of forwarding to your mobile. If you use the inbound number a lot you can generally pay about $8-10 a month and receive unlimited calls.

If you have access to broadband Internet during your holiday and can get a softphone installed on your computer, or a hardware SIP phone, you can receive calls from the US at the 1.5 cent rate (or free if you bought unlimited) and place outgoing really cheaply, too.

This is a better solution if you want to take advantage of this on a frequent basis.

VoIP isn't all that hard to figure out. I've abandoned the providers that package everything in favour of the a la carte method. For all but the most extreme usage it's cheaper, and it's rather fun, like mobile phones are.
