Since I tend to hop on a few countries when travelling, it would be great to grab a single SIM card for use in different countries.
I've been looking at the services offered by Travelsim (based in Australia) but have also found US sites such as Passport International SIM and OneSIM Card International and a UK site called WorldSIM.
The rates appear more expensive then buying SIM cards in every country you travel, but the convenience of have one number when travelling might make the extra cost worth it.
Anyone tried these, and if so, what are your experiences?
I see what you mean, for that issue we had a skype number so that you can link that to your cell phonenumber. In south east asia you have a global network, but for us it was better to buy sim cards in every country because for example in the Philippines you could top up that card with 5 dollar for 24/7 internet acces on your cellphone or, once conected to netbook on your computer. More benefits for buying them in each country for us.
