I've used OneSimCard for a couple of years now and have been very pleased. It is a well established company with a good track record.
It is simple to use, excellent value for money, reliable, has extensive coverage [at least in France, Italy & Switzerland, where I was], and the website is easy to use.
I've recommended OneSimCard to my siblings and friends.
One thing when ordering is to make sure you get the right size of sim card for your phone. I use quite a lot of data when travelling, so for me it is best to pre-purchase a large data pack [eg. 200 MB].
It would be great if OneSimCard allowed tethering, so that I could hook my laptop to my phone and get an internet connection that way.
