Thailand eSIM questions
Which network will I use in Thailand?
Dayo connects to AIS, 5G, with 5G or 4G where available. If that network is busy, your phone can switch to a partner network automatically.
Will I have data as soon as I land at Suvarnabhumi (BKK)?
Yes. Install Dayo at home before you fly, then turn it on when you land. Your plan's days start the first time it connects in Thailand, so you can book a Grab from the arrivals hall.
Does it work outside Bangkok?
Yes. Your plan works anywhere the network covers in Thailand, including Chiang Mai, Phuket.
Visiting more than one country?
A regional plan may be better: Southeast Asia, Asia 9 covers Thailand and its neighbours on one eSIM.
