| | Re: Help w/international SIM Card
You need to look at all the options. If you were to get a UK SIM, then that would only be OK for the UK and you'd need to get local SIMs in every country you visit.
I would recommend an international SIM as this way you only have to buy one SIM for the two month trip. Otherwise you'll be juggling SIMs and will lose any credit you have on that SIM when you visit another country.
Have you checked out Aether Mobile? Their service covers all the countries you've mentioned (well over 200 in all), and they offer free incoming calls in 76 countries. I've used their service for a few years when I travel and my Berry is unlocked already so I could use it straightaway. Their rates are really good and very competitive. Check out their website. I'd highly recommend them. It's easy to use, easy to top up when you need to and there's no expiry on the SIM or the credit.
