Reviews: Thailand AIS 5G SIM Card | 15GB for 7days | Local Phone Number | Pick Up at Bangkok Airport
Guest User2026-09-14
Very convenient for trips to Phuket if you need a physical SIM card. Booking and payment are easy. We quickly found the right counter at the airport. We speak very little English, but the staff understood us and took care of everything. They inserted the SIM card and activated everything themselves. We had no problems. The connection in Phuket worked well, and the internet connection was stable. We shared internet with additional devices without any issues, and the quality never dropped. Overall, we were satisfied. One downside is the maximum package at the airport is 7 days; I would have liked longer packages of 10/14/21/30 days.

Great price and great service. Booking, payment, and activation are easy. We purchased in advance, followed the instructions, landed in the country, turned on the phone, and had internet access. Connection quality was good, with no interruptions. We didn't have to use customer support. We were completely satisfied with the service.

It's very convenient when you don't have to rely on Wi-Fi. Internet is available everywhere (I didn't go into the jungle). I'm very happy with the SIM card. I recommend it.

This was my first time purchasing a Thai eSIM from TripAdvisor. I bought a 35GB/7-day plan. Following the instructions, I completed the real-name registration on my local network. Upon arrival at the Thai airport, installation was a breeze. It worked smoothly, mostly within Bangkok, and also easily when traveling to Ayutthaya. Upon landing, it automatically switched back to my domestic telecom provider, which was very convenient. The eSIM is very convenient and reasonably priced (less than 150 NTD). I would definitely repurchase it and recommend it to anyone who needs one.

I had a great experience using this eSIM in the Philippines. What impressed me most was how consistent the connection was while moving between different destinations. The setup instructions were clear, and I was online within minutes without needing to remove my physical SIM. The data connection was fast enough for navigation, online bookings, social media, and video calls. Coverage was also very good during my travels between islands, which was particularly useful when relying on my phone for transport and directions. I experienced no significant downtime or connection issues. Overall, it was a practical and dependable option that made travelling around the Philippines much easier.
