Very easy. A much better and less expensive option…

I waited to insert my ORANGE SIM until I got to the UK and it activated automatically. Very easy. A much better and less expensive option than using data from your US carrier. SimOptions support responded quickly and helped me work through an issue I had with the carrier. Recommended.
Emily

The connection in the UK has been best…

I have been using the sim card from three UK for almost 3 weeks, in Germany, France and UK. The connection in the UK has been best in the UK by far. However, comparable sim cards at airports were much more expensive. I can recommend this option.
