Bangkok and Phuket sibeh crowded, sometimes the Wi-Fi will spin like sotong kena goreng. But if go ulu places with fewer people, the connection damn fast one.

I bought it right away in Russia, and upon arrival, everything worked without a hitch. I used the only e-SIM for the whole family, just sharing the internet. It works flawlessly, no complaints, highly recommended!

Easy to set up. Clear instruction. When I arrive at the airport, the service is ready to use and I can use the GRAB app and order a taxi to fetch my family and I to the hotel.

I went to Vietnam → Cambodia on a woman's solo trip and stayed in Cambodia for 9 nights (Phnom Penh 2 nights, Krache 1 night, Siem Reap 6 nights) ♪ Thanks to this eSIM, it was a fulfilling trip ^ ^ Use again Shu!
