I'm a (lukewarm) fan of Truphone, have two of their SIM cards (one for the wife). Have used them in the UK and Australia, with cheap call rates and data, and let visiting friends and family use one. I like having a US number on the SIM when I travel to the UK, so I can forward calls easily and inexpensively.

Used recently in Mexico as well, but they tried to charge me much higher than the advertised rates. There are a lot of "errors" in the rate pages, and then you have to fight to get reimbursement (which they eventually did). The SIM card would not work on an NCL cruise ship.

With the right package, I'd abandon my primary carrier (TMob in the US). But there have been endless delays for Truphone in rolling out new countries. Still beats Geosim and Maxroam in most places, and more convenient but more expensive than local sim cards in each country. With the EU bringing in more control over roaming costs, Truphone might face an uphill struggle.
