Yes. It also includes 100 Baht credit calls + FREE calls to AIS network numbers.

AIS has the best network infrastructure in Thailand and this eSIM delivers on that promise. Used the 10-day plan and network performance was consistent. The data allocation works well for typical tourist activities. Voice features are comprehensive with both credit and unlimited AIS calls. Good overall package.
Perfect for my 8-day Thailand adventure. AIS network provided strong 5G speeds throughout Bangkok and Phuket. 30GB was more than enough for my usage pattern. The local phone number made everything easier, and the calling features saved money. Easy activation process and responsive customer support.
AIS network quality is outstanding and coverage is comprehensive. However, if you’re a heavy data user like me, the 30GB limit before throttling can be restrictive. The calling features are excellent though. For moderate users, this is a great choice with good value.
If you’re not a heavy data user, this AIS eSIM is perfect. 30GB at full 5G speed lasted me 8 days easily with normal usage – maps, social media, video calls. The calling features are excellent with 100 Baht credit plus free AIS calls. Network quality was outstanding everywhere I went in Thailand.
While AIS network coverage is excellent, the speed throttling after 30GB was more limiting than expected. For heavy streamers and content creators, this might not be ideal. However, the voice calling features are great and the initial 30GB at full speed is very fast. Good for light to moderate users.
