    Here's what our customer's have to say!

    • Great Value

      Friend recommended this to me and bought one each for me and my girlfriend. setup was easy as and had no issues.

      Would have been happy even if it was slower since it's like a quarterr of the price of the ones you get at the airport

    • Cheap, easy to setup

      Worked well for everything I needed it for - google translate, grab and insta. Pretty straight forward but don't be like me and try set it up before you get to Indonesia to save on headaches as you need internet to activate.

      Samuel L. - Indonesia 

    • Worked as expected

      I was a bit confused on how it works, but the instructions that i got afterwards were easy enough to follow. Once it was set up, i didnt have to think about it again. so that was definitely a positive

    • Life Saver

      Honestly a life saver. The amount of times we got lost trying to find our way around. i could not imagine not having data

    • Cheap and Easy

      Actually got 2 of these sims for my parents when they went to China - Was easy to setup for them but can't directly comment on the performance since I wasn't there. But had no complaints from them

    • Best Value for My Japan Trip!

      KoalaSim was not only super easy to use but also much cheaper than the alternatives I looked at. It worked perfectly across Tokyo, Kyoto, and Osaka—highly recommend!
