Network reliability and price per GB carry the most weight: coverage is excellent in Bangkok and major cities, but gaps still exist on the islands and in the North. It's the choice of network and how the eSIM handles app filtering that makes the difference.

Coverage
voilà eSIM relies on AIS, the number one network for coverage in Thailand, as well as DTAC and TrueMove H.

The connection remains stable from the first to the last day.
Pricing
The price drops to $0.90 per GB on the 20 GB plan, valid for 30 days. voilà eSIM offers the best value for money in this comparison: AIS network, easy-to-use application, and human support included. Plans adapt to the duration of your stay. You pay for data, nothing else: no hidden extra costs, and hotspot sharing is included.
Activation
The eSIM is easy to install: you purchase and install it in two minutes from the easy-to-use voilà eSIM app. You scan a QR code before departure, without handling a physical card. The line activates as soon as you land in Thailand, and you keep your usual number for calls and SMS.
