I installed the SIM card while in Moscow, following the instructions I received in the email. There were no issues; as soon as we landed in Phuket, everything worked automatically. I have a number, receive text messages, and can register in any app. I personally have 5G everywhere on the island, everything is great, I recommend it to everyone. P.S. Samsung phone

The price with the promo code is fantastic!!! 182 rubles for a week, 2 GB with tethering!!! I'll try it again next time I go. The eSIM installation instructions are clear and easy to understand.

I bought an eSIM a week before the trip. I turned it on immediately after landing. The internet worked perfectly for the entire 10 days, and I had access to all the social media I needed. Thank you!

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.

It's convenient because you can find it right after exiting the departure hall. The staff was friendly and set it up quickly. The signal was decent, and I used it well. However, I was a little worried because my plan was suspended after 35GB, which was a bit of a concern. I was satisfied because the price was cheaper than buying unlimited data on-site.
