Vietnam eSIM questions
Which network will I use in Vietnam?
Dayo connects to Viettel, 4G LTE. If that network is busy, your phone can switch to a partner network automatically.
Will I have data as soon as I land at Tan Son Nhat (SGN)?
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 Vietnam, so you can book a Grab from the arrivals hall.
Does it work outside Ho Chi Minh City?
Yes. Your plan works anywhere the network covers in Vietnam, including Hanoi, Da Nang.
Visiting more than one country?
A regional plan may be better: Southeast Asia, Asia 9 covers Vietnam and its neighbours on one eSIM.
