We've installed it on the phone. We'll connect it when we arrive in Thailand. We hope everything will be fine. We can't yet determine the signal quality.★

Guest User2026-01-11
I used this in KL, Bangkok and Shanghai. Overall the signal was ok. Sometimes we do get a drop out but it’s not often. We managed to use all social media platforms with this eSIM at Shanghai. Only thing is if you want to hail a ride you’ll need a number for it in china.★

Reviews: Southeast Asia 5 Destinations 5G eSIM | Singapore, Malaysia, Thailand, Vietnam, Indonesia | 1–30 Days | Instant QR
Guest User2026-03-01
• Super easy setup: Simply scan a QR code to complete the setup; no need to remove or insert the SIM card.
• Uninterrupted service for your original number: You can retain your original number to receive SMS messages (crucial for receiving bank verification codes!) while using international data.
• Buy and use instantly: If you run out of data, you can easily add more with a few taps on your phone; no need to search for physical stores.
• Stable network speed: Navigation, sending social media updates, and watching videos were all very smooth during my trip abroad; I almost never encountered any network outages.★

Easy to use, I faced some difficulties with real face authentication but the customer service was fast and solved my problem, so I was impressed. I will always use Trip from now on.
