wrapping things up in Boston

I am taking my laptop with me to Europe. I'll try to be as connected as I can. I have a network card as well as a modem built-in. I've been looking for a Europe-wide dial-up ISP with toll-free numbers, but nothing has been satisfactory.

My ATT account is about to be canceled, so I will also need a POP account.

Any suggestions? Would a calling card be a reasonable solution?

I've just taken a loot at netstumbler.com, but it doesn't look that helpful.
