Great! Just plug & play!

Bought this and used it on my unlocked Huawei mifi router, by just setting the correct APN, it was good to go! However, take note of the rates offered by the network carrier you are roaming in. Within any country, some carriers are priced cheaper than others, so be sure to check out their website to see which carrier offers the cheapest rates to maximise your credits.

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.

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
