What our users say about our UK Travel SIM Card
Read about our customers experiences with our UK Travel SIM card and our service
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.
This product and service is Amazing! Highly recommend
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.
