You would be better off buying "a pay as you go" dongle in each country.
What ever you do NOT buy or take one from the UK and use it abroad. It can be and is prohibitively expensive.
People have been caught out using them as shown by BBC's Watchdog last year when people were getting bills ranging from £1,200 to £9,000 when they got back to the UK. [yes those are the right figures]. And if you go over your limit you are talking about £4.50 per Mb upload AND download as it is International Data Exchange rates.
Either use an Internet cafè or local free wi-fi connections.
all dongles you buy here will work but you will be on roaming so it is mighty expensive. Buy a pay as you go dongle in the country you are in it will be a lot cheaper
