Hi guys - I am a copywriter and travel to various places I own in Spain, France, USA and UK. I have a computer in each for writing and design and communicating with clients. My question is: What method do you use to access Internet and email that can be used in any country?

I don't want to have to install a landline in each place, and sign up for broadband etc. I will be sending large attachments.

I understand some mobile phones can be used as a mobile modem to connect up to the Internet, but will obviously need to know a bit about what telephone service to use. In the States, Cingular is the only phone service that works in our area. In the UK, it's something else.

I don't own a mobile phone, by the way, but I will buy anything that will work overseas.

Thanks for your help!
