Out of sheer frustration I started to carry a bunch of pay-as-you-go sims for popular countries but recharging those is often a hassle. This international data mess has been a frequent conversation topic with fellow travelers and no one has a good, simple and reliable solution.
This summer however things changed. Some friends brought me into contact with Phillip Attore in Amsterdam who was running a Beta test for a new business: rent a mifi device for a few dollars a day with 50MB per day included. You can use the device world-wide and the cost is fixed on a daily basis.
