Great SIM! Perfect for a longer trip abroad!

As a first time user, I am very satisfied. There's a bit of a learning curve if you've never used a SIM before, which was my situation, but it doesn't take long to figure things out. And the rates are superb! It's so nice not to have to worry about excessive roaming charges on your "home" carrier.

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.
