Really easy to use, good service quality and what I liked the most is the variability of formats (days / volume of internet traffic)

Very convenient and affordable eSIM! Easy to purchase and activate through Trip.com. The 5G connection in Indonesia was fast and stable, making it easy to use Google Maps, WhatsApp and browse the internet while travelling, especially during my trip at JAKARTA & BANDUNG! No need to change physical SIM cards. Definitely worth it and highly recommended!

Excellent. I always get an e-SIM; I don't have to worry about a physical card. I'm always connected, and everything works. The price is great.

Always Connected in Thailand: Our Experience with eSIM True 🇹🇭 When traveling in Thailand, mobile internet is almost as essential as comfortable shoes. It's essential for maps, taxis, translation services, finding interesting places, and, of course, beautiful photos you'll want to share. To avoid wasting time buying a local SIM card upon arrival, we purchased an eSIM True in advance for 11 days with 2GB per day. Activation was a breeze: just scan the QR code and you're ready to use the internet. No lines or unnecessary fuss! But the most important thing is the connection quality. The internet connection is excellent, not only on the mainland but also on Koh Larn Island. Even far from the hustle and bustle of the city, you can easily use maps and stay connected. In the end, eSIM True became one of those small solutions that makes traveling more comfortable. No need to search for Wi-Fi, depend on hotels, or worry about how to get to your destination. Sometimes it's the little things like these that really make traveling more enjoyable! 🌴
