I travelled through Thailand

I travelled through Thailand, Malaysia and Singapore and Travelkon kept me connected seemless all the way through. Second time to use their esim card and I love it.

Ideal eSim for south East asia

We got 3 eSims for the family. We had good connectivity and 5G connectivity in Kuala Lumpur, Langkawi, Hanoi and Ninh Bin. The sim operator is 3HK, so there were restrictions to accessing some websites.

Customer service is excellent
