Seamless hook up - the physical SIM card positioned in my Oppo phone and was working effortlessly by the time I left Saigon airport. No dramas across the 30 day expiry . Very satisfied with the product. (do allow 10 days before you go for a 'standard' delivery of the SIM).

Will use travelKon again on my next travel.

Never missed a beat! Even in the jungles of Borneo and a random turtle island off the coast of Malaysia! Very satisfied! Highly recommend

I highly recommend purchasing an eSIM when traveling overseas. It made our trip so much easier since we didn’t have to search for free Wi-Fi wherever we went. We were able to stay in constant contact with each other and our driver, and having reliable internet access for maps and exploring nearby attractions made everything completely stress-free. The setup process was simple, the connection was reliable, and the cost was very affordable — definitely a worthwhile investment for any traveler.

Bought the esim for use in Thailand, Malaysia, Indonesia, Singapore etc.
It was dead easy to install.
So far only using in Bali and no problem with network coverage.
