eSIM Vietnam

Need a hand at 2am before a Bali flight? HelloRoam support is available 24/7. Message us and a real person responds in under 2 minutes. Whether you're troubleshooting mobile data mid-trip or need a top-up on your prepaid data package, help arrives fast.

Connect to local 4G LTE and 5G networks the moment you land in Vietnam, at a fraction of what Telstra, Optus, or Vodafone AU charge for international roaming. Plans start from A$4.85 per day with no lock-in contract and no activation fees. It's the most affordable way to get internet abroad without a Telstra Day Pass eating into your travel budget.

Keep your Telstra, Optus, or Vodafone AU number active for calls and texts. HelloRoam handles your data through a second eSIM line on any dual SIM compatible phone. Your wireless connectivity for data runs separately, so friends and family back home can still reach your usual number.

HelloRoam connects to 204+ carrier networks across 185+ countries. Fixed data and unlimited data plans available. If a faster 4G or 5G signal is nearby, your phone switches to it automatically. With cellular coverage this broad, you get reliable internet abroad whether you're in a city centre or off the beaten track.

HelloRoam alerts you at 80% usage so you're never caught short mid-trip. Top up instantly from the app without reinstalling your eSIM. Adding more mobile data takes under a minute, so your prepaid data package keeps up with your trip rather than the other way round.

Connect on trusted local 4G LTE and 5G networks in Vietnam. HelloRoam picks the strongest signal for calls, navigation, and streaming. Local network speeds mean you get the same fast mobile data as residents, not the throttled tier most carriers offer for international roaming.

Planning a multi-country trip? HelloRoam regional eSIMs cover Asia Pacific, Europe, and 185+ destinations in one purchase. eSIMs for Europe span 34+ countries. Japan, Bali, Thailand, and NZ all sorted. One prepaid data package covers your whole itinerary, with no SIM card to swap at each border.

Share your Vietnam eSIM data with a laptop or tablet using your phone's hotspot. No extra fees, no setup. Works on all eSIM compatible phones. Your wireless connectivity extends to every device in the group, so the whole crew stays online from a single prepaid data package.
