Frequently asked questions

Everything you need to know about your Vietnam eSIM

Is the data truly unlimited? +

Yes — there is no data cap and your connection is never switched off. Like every unlimited travel eSIM, the plan carries a daily full-speed allowance: in Vietnam that is 3 GB per day. Beyond it you stay online at a reduced speed (1 Mbps) for the rest of that day, and full speed returns automatically the next day. Hotspot traffic counts towards the same allowance. We publish the exact figure for all 181 destinations — see our daily allowance by country.

When does my eSIM activate? +

Your eSIM activates the moment you first connect in Vietnam. Your days don't start until you're there — so you can install it weeks before travel with no waste.

Which devices are compatible? +

Any unlocked eSIM-compatible device: iPhone XS and later, Google Pixel 3+, Samsung Galaxy S21+, and most modern Android flagships. Check Settings → Cellular → Add eSIM to confirm.

How do I install the eSIM? +

After purchase, check your email for the QR code. On your phone: Settings → Cellular (or Mobile Data) → Add eSIM → Scan QR Code. It takes under 2 minutes. Full step-by-step instructions are included in the email.

What if I need help? +

Our team is available 24/7 via live chat at aerosims.com — day or night, before or during your trip.

Does the Vietnam eSIM work in rural areas and Ha Long Bay? +

Yes. Coverage extends across all major tourist regions and most rural provinces through Viettel's nationwide network — including Ha Long Bay, Sapa's mountains, the Mekong Delta and the central coast. You stay connected far beyond the big cities.

Can I use my Vietnam eSIM as a hotspot for other devices? +

Yes — tethering and mobile hotspot are fully included — share your unlimited connection with a laptop, tablet or a travel companion's phone while exploring Vietnam, at no extra cost. One thing worth knowing: hotspot traffic counts towards the same 3 GB daily full-speed allowance, and tablets or laptops get through it faster than a phone. If you plan to keep several devices online all day, one of our data packages with a fixed GB volume is usually the better fit.

Could my internet speed ever change? +

Yes — once you pass the daily full-speed allowance, which in Vietnam is 3 GB per day. After that, data keeps working at a reduced speed (1 Mbps) for the rest of that day and returns to full speed the next day. Nothing is cut off, and hotspot traffic counts towards the same allowance. This tier is set by the local operator, not by AeroSims. Full details for every destination: daily allowance by country. If you prefer a guaranteed volume at full speed, our data packages give you a fixed number of GB.

Can I extend it if I stay longer? +

Often yes. While the eSIM is still active, open your personal eSIM page — the link is in your delivery email — and you will see there whether extra days can be added to your plan. If they can't, another eSIM for the same destination arrives by email and installs alongside the one you already have.
