It’s a great service with a great price

For so long I was looking for a genuine prepaid connection to use in and out of Canada and I initially bought 1 number. Eventually I have now three accounts. So happy.

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

Best network for travellers

I am working on a cruise ship and always travel around the world and need to use my phone. I can use World Sim everywhere even in Namibia in the desert which is great. I couldn't do this with the other services providers.

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.
