Guest User2025-12-25

Excellent e-SIM, you can easily choose a plan. Internet and signal are excellent, coverage is everywhere. Activation on an iPhone via QR code or the Trip app itself is instant, I definitely recommend it. The price is better than in Thailand, unless you try to buy from Seven, but Thais rarely sell cheap SIM cards there.

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.

We bought an eSIM before our trip to Thailand and couldn't be happier! We activated the service in advance, arrived at Phuket airport, and the internet was working right away, without any delays or hassle. Reliable connection everywhere. Now we can use the internet all over the island without any problems: at the hotel, on the beach, on public transport—the speed is stable, the coverage is excellent. Even in remote areas, the signal is reliable, which is ideal for a family with a child. A bonus—we also received a local number and a Thai mobile number, so we can sometimes call each other without extra charges—it's convenient and affordable. Of course, the internet is what we mostly use: maps, chats, video—everything works. We recommend eSIM to all tourists in Thailand!

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!
