Reviews: Thailand AIS 5G SIM Card | 35GB for 7days | Local Phone Number | Pick Up at Bangkok Airport
Guest User2026-01-21
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.

Excellent connection. I bought it for my wife's phone. 2GB of data was more than enough, plus it supports tethering. I recommend it.

🌏📶《Scan and Connect! A Real Experience Using an eSIM in Chiang Mai, Thailand》 During my recent trip to Thailand, I purchased a DTAC 5G eSIM directly from Trip.com. No need to change SIM cards or visit stores—the whole process was incredibly convenient! Here's my experience using it in Chiang Mai👇 ⸻ ✈️ Super Easy Activation｜A Boon for Lazy People 📲 Received a QR Code immediately after purchase 📲 Scan with your phone → Installation completed in minutes No need to queue at the airport to buy a SIM card, and no need to worry about language barriers. 👉 A huge plus for those who want to use Grab and Google Maps immediately after landing! ⸻ 📶 Network Speed ​​Performance｜Stable throughout Chiang Mai! I used it in Chiang Mai city (Nyeman and Old City area): ✨ Instagram / LINE / Google Maps worked perfectly. ✨ Video streaming (YouTube, Reels) was almost smooth. ✨ Sharing my hotspot with friends was also great. DTAC is one of the main coverage areas in tourist cities like Chiang Mai, and the overall connection stability was good. ⸻ 📍 Usage Scenarios Sharing | Truly Convenient 📍 Ordering Grab 🚗: Instant location, no lag 📍 Finding restaurants 🍜: Google Maps opens instantly 📍 Uploading Moments 📸: No need to wait for Wi-Fi 👉 No more searching for cafes to use Wi-Fi, making my travel pace much easier. ⸻ ⚠️ Important Reminder Many people overlook this, so I've compiled it for you below 👇 🔸 eSIM "usually starts counting down from download or activation" (Installing too early may waste days) 🔸 Recommendations: 👉 It's best to install it before departure or on the day of arrival. 🔸 A few people may encounter activation problems (such as not receiving a signal). 👉 It is recommended to keep your order and screenshots for future reference. 👉 You can contact customer service directly if you have any problems. ⸻ 💰 Overall Experience Rating ⭐️⭐️⭐️⭐️☆ (4/5) 👍 Advantages ✔ Super convenient (no need to change SIM cards) ✔ Stable network speed (works very well in urban areas) ✔ Affordable price 👀 Minor Disadvantages ✖ Be sure to activate at the right time. ✖ Occasionally there may be activation problems (the probability is low). ⸻ 💬 In short 👉 "This eSIM..." It lets you jump straight into travel mode the moment you step off the plane! No need to search for Wi-Fi or change SIM cards, just start navigating to find places to eat, drink, and have fun. In a relaxed and comfortable city like Chiang Mai, it's a real plus! 🥰

Reviews: Thailand AIS 5G eSIM | Total 30GB/35GB | Local Phone Number | Real-Name Authentication Required | QR code

Everything is great, very fast internet!!! The only difficulty is that you need to attach a copy of your passport and take a selfie on the operator's website (to activate the number), but overall everything is very good.
