It is a good service for what it is for

The reason we purchased WorldSIM is to save us the inconvenience of purchasing SIM cards in every different country. The 7" Android Tablets and the Android Dual-SIM phones we purchased (we purchased 4 devices being 2 of each) are quite good and work well.

My WorldSIM experience was just what I was hoping for

Activating the service was immediate – just turned on my phone and I was connected. As I traveled through six countries, I always had efficient service to call a local restaurant or to call home thousands of miles away.

Perfect for travelers!

I used WorldSIM several times during my trips in Europe and America without any problems. The phone changed the networks automatically and I never lost the signal. Very good coverage on those areas.

Essential travel companion

I travel to the US a few times a year and have been using a WorldSim card for a while. I have just upgraded to their new card and am very pleased. The rates are unbeatable and the process of moving my credit and number over went smoothly.
