Questions about eSIM in Vietnam
What is the best eSIM for Vietnam?
The one you can check before you pay: which Vietnamese network it uses, whether its data is counted per day or in total, the number of days, the price with tax, and the refund rule. The plans here cost from US$5.88 with tax, run for 7 to 30 days on Vietnamese networks, and are refunded in full if they do not work and cannot be fixed.
How does a Vietnam eSIM work?
The QR code goes onto the phone at home, over Wi-Fi, with the line left off. Once you have landed, bring it up and give it the mobile data role. Your usual SIM stays in the phone, so your own number keeps working on WhatsApp.
Do I need a Vietnam SIM card at the airport?
No, if the eSIM is installed. A SIM card bought in Vietnam is registered at the point of sale, usually with your passport, and comes with a Vietnamese number. The plans here state on each card whether calls or a number are included.
Is there a Vietnam eSIM with phone number?
Yes, on the plans marked with a number. Each card states whether the plan includes calls or a Vietnamese phone number before you pay. The rest are data only, and your own number stays in the phone either way.
Does Vietnam have eSIM?
Yes. The store sells Vietnam eSIM plans you install from a QR code before you fly, and they run on Vietnamese networks: Viettel, VinaPhone or MobiFone. You switch the line on when you land, and nothing needs collecting at the airport.
What is Local SIM Vietnam?
