Reviews: Thailand | 5G eSIM | Day Pass/Total Package | 24H Billing | 1-30 days | QR code

📶 eSIM Review
Fast activation, everything connected without any hassle. The price is reasonable, especially compared to buying a physical SIM card at the airport.
The internet was stable in most areas, but the connection was a bit spotty in the Siam area. Speeds dropped, and there were occasional signal drops. Perhaps due to the high traffic volume, as it's a busy area.
I liked that you can extend your data plan if you run out. It's quick and easy, without having to change your profile.
My personal thoughts
For a short trip, this is a convenient option. No need to search for retail outlets, change SIM cards, or store your own card separately. Everything is on your phone and ready to go.
If you need maximum stability, especially in the city center with densely populated areas and crowds, you might want to consider top-tier carriers directly.
But in terms of price-to-convenience ratio, this is a perfectly acceptable option.★

Excellent, I took 30 GB in a month, and I haven't even used half of it, even though I used the internet constantly.★

Everything went well, the internet worked perfectly throughout the entire trip, even on the Semilan Islands. I didn't connect to the internet for calls; I was too lazy to find an office.★

I couldn't install it right away because I had to register for the app first. Read the instructions carefully.★

Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.★

This was my first time using an eSIM card. I liked it: it was easy to register and activate on my phone. I got it for 13 days and used it in Thailand, sharing internet with a second phone. The signal was good, and everything loaded quickly. I used local messaging apps to order food and groceries. I also used Russian messaging apps for video calls home.
