Your phone joins whichever partner network has the strongest signal — nothing to pick manually. A few plans use one network only; each plan page lists its exact networks. Data only: calls and texts stay on your home SIM.

About Thailand eSIM
VoyaSIM's Thailand eSIM connects to AIS, dtac, or TrueMove H (varies by plan), with 4G/LTE in cities and tourist areas; 5G in Bangkok and Phuket. Coverage spans Bangkok, Phuket, Chiang Mai, Krabi, Koh Samui, and Pattaya.
Good to know: On southern islands such as Koh Phangan and Koh Tao, AIS and dtac give the strongest coverage near beach areas; remote inland hiking trails can be patchy.
How it works: Choose a plan above, complete checkout, and receive your QR code by email. On iPhone, go to Settings → Cellular → Add Cellular Plan and scan. On Android, go to Settings → Network & Internet → Mobile Network → Add Carrier.
Refund policy: A full refund is available if the eSIM has not been activated. For technical issues that prevent activation, contact [email protected].
