eSIM Vietnam

Need help at 2 AM in Tokyo or midnight in Cancun? HelloRoam support is available 24/7. Message us and a real person responds in under 2 minutes. No bots, no hold queue. Whether you're troubleshooting mobile data access or topping up your prepaid data package mid-trip, our team has you covered around the clock.

Get fast 5G and 4G LTE data from the moment you land in Vietnam. No Bell, Rogers, or Telus roaming fees. Set up your eSIM before you leave home in under 2 minutes. A prepaid data package activates on arrival so your wireless connectivity starts the second you step off the plane.

Keep your Bell, Rogers, or Telus number active for calls and texts. HelloRoam runs as a second eSIM line on any dual SIM compatible phone, so you never miss a call from home while travelling. Your cellular coverage for internet abroad runs on a separate line, so both SIMs work at the same time.

HelloRoam connects to 204+ carrier networks across 185+ countries. Your cell phone switches to the strongest available 4G LTE or 5G signal automatically. That broad network reach means consistent mobile data access whether you're in a busy city centre or a smaller town.

HelloRoam alerts you at 80% data usage so you never hit a surprise cap mid-trip. Top up instantly from the app without reinstalling your eSIM or visiting a store. Keeping your internet abroad budget in check is simple when you can add more mobile data in seconds.

Your Vietnam eSIM connects to trusted local 4G LTE and 5G networks. HelloRoam picks the strongest available signal for navigation, streaming, and video calls. Reliable cellular coverage at local network speeds makes a real difference when you're navigating a new city or video calling family back home.

Travelling to multiple countries? HelloRoam regional eSIM plans cover Europe, the Caribbean, Asia, and 185+ destinations in one purchase. Fixed and unlimited data options available. One account, no SIM swaps. A single international data plan with cross-border wireless connectivity saves you the hassle of buying a new prepaid data package at every border.

Share your Vietnam eSIM data with a laptop or tablet using your cell phone's built-in hotspot. No extra fees, no setup needed. Works on all eSIM compatible phones. Turning your phone into a mobile Wi-Fi hub means everyone on your trip gets internet abroad from the same prepaid data package.
