Reviews: Thailand 5G eSIM | TikTok & ChatGPT Available | Day Pass/Total Data Package | 24-Hour Billing | QR Code
Guest User2026-02-22
Great, got a 7-day plan (can be upgraded to any number of days) with 2 GB per day. Price: 186 rubles for a week of high-speed mobile internet. I thought it was a scam, but everything worked perfectly. 5G speed: 250 Mbps. I recommend it.★

I had no trouble activating my Trip.com account. The connection was stable, only working while out at sea on the way to the Similan Islands. I shared it with three other devices, and they all worked without issue. I didn't use the phone service, so I'd recommend considering a data-only plan.★

Guest User2026-02-21
I spent 8 days in Thailand and the internet was super smooth. However, 50GB was really too much; I only used less than 20GB in the end, which was a little wasteful. But it's still really necessary to prepare that much data. I had signal everywhere 📶 and could use my phone without worry. You can also install it directly from tirp.com, which is very easy to use. Will I buy it again for my next trip?!★

Best connection, did not have any problems with it even when we went island hopping. Was connected the whole time. Though would advise one to do the authentication before flying put as it can be a bit complicated.
