Before you go (Hoi An)

Install the eSIM at home on Wi-Fi and keep the line switched off until you land. Download offline maps and your tickets while you still have Wi-Fi, in case a merchant house or a boat trip has no signal. On arrival, switch the eSIM line on, choose it for mobile data and turn on data roaming for that line only.
