Worldwide Data SIM Card for travel, holidays

Avoid it, hassle and top up... top top up...

I found the worldsim website not to be the easiest to figure out but once I got set up it was simple enough. Just stick the sim in and away you go, anywhere in the world. I would advise buying a data bundle. If you don't, you can connect to the Internet no bother, but it's fairly expensive, costing several cents per megabyte. And believe me, a megabyte doesn't get you very far these days, and it adds up very quickly. During a day of very moderate usage I got through $10. Whereas if you buy a data bundle, you know exactly what you're paying, and you can choose to have anything from 250mb to 2gb per day, for a couple of dollars.Overall, worldsim is a decent product, but I would like to see a more user friendly website.

You can get these for free on their website.
