I connected without any problems while I was right there in Thailand. This was my first time connecting an eSIM. Now I only use this method to select and connect a SIM card when connecting. 👍👍👍

Excellent connection, quick installation, and we connected via Wi-Fi while we were already on-site. For convenience, it's best to activate it at home the day before your trip.

Reviews: Southeast Asia (7 countries) | 5G/4G eSIM | Daily plan/Data package | 24-hour billing | 1 - 30 days | QR code

The price-quality ratio is the best. We've never had any problems since installation. It's always 5G-enabled, and even in more remote areas, the signal is good. We moved to a different country and there were no issues. We'll definitely buy it again when we travel. It's the best option, without a doubt.

Easy to use, eSim loads directly from Trip.com app, switch on phone at destination, and good to go. Better signal than back home!
