Best SIM on the market

It's great that wherever I am in the world my family, friends and work colleagues can be in touch. Also I'm able to conduct business wherever I roam without clients even knowing I'm not at home or in my office

I purchased the World SIM a few months back and since then I have used it in various countries with great satisfaction. The pricing structure is very competitive and service is highly reliable. If you travel to various countries and need a great world product then this SIM is the right move.

A nice decent service

I think that is a unique service very practical especially for frequent travellers. According my experience has the best value for money ratio. Its flexible and extensible. You can add on local numbers at any time, just for the period that you need them. By this way clients abroad can reach you by calling a local number. Very clever!

Great to know I can just turn on my phone and be connected anywhere I travel.

Easy to use and a very reliable service. Cheap calls and so easy to use when abroad. Always have a clear line no matter where I have travelled. This is a brilliant service I only wish I had subscribed sooner, it would have made my trips a lot easier in regards to arranging phone calls in foreign countries.
