Works a treat, great value!

I used a TravelKon esim for Japan in January and it worked a treat. I looked around out of curiosity at other options but TravelKon still provides the best value for money for whatI need. 20GB of data has been perfect for me, set up was quick and easy and worked as soon as we landed in Singapore. And it's worked perfectly across Malaysia & Indonesia. Highly recommended! Until our next overseas trip...

Worked really well in South East Asia

Worked in Malaysia, Cambodia and Vietnam without issue.

It was great it just worked
