eSIM Travel Tips for Vietnam
Vietnam north to south: your eSIM keeps you connected throughout
The classic NZ backpacker route is Hanoi to Ho Chi Minh City or vice versa. A HelloRoam eSIM sorted at home in Auckland means you arrive in Hanoi already connected. Your signal follows you down the tourist spine from Hanoi to HCMC on the same plan.
Grab and local apps need live data
Grab works across all major Vietnamese cities. In Hanoi and HCMC it is the safest and most transparent way to get around. Your HelloRoam eSIM keeps Grab and Google Maps running from the moment you arrive.
Ha Long Bay boat trips lose signal
Ha Long Bay overnight cruises from Hanoi take you out into the open bay where signal is very limited on the water. Download offline maps and your cruise itinerary before leaving your Hanoi hotel.
Sapa mountain trekking has patchy signal
Sapa town has reasonable 4G but trekking routes into the terraced rice paddy valleys and staying in hill tribe homestays can have very limited signal. Download your trekking route maps offline before arriving in Sapa.
Hoi An old town is very well covered
Hoi An's old town, lantern festival streets, and the An Bang Beach area all have solid 4G coverage. Restaurant booking apps and tour booking platforms run well on HelloRoam's Vietnamese network.
Mobile networks in Vietnam: what NZ visitors need to know
HelloRoam connects on Vinaphone and Viettel Mobile in Vietnam. Viettel covers cities, coastal towns, and rural provinces alike. Vinaphone and MobiFone are strong in urban areas. Multiple network options give good coverage redundancy along the tourist trail.

Cat
On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!
Rated 5 out of 5 by this reviewer
Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.

Transparency Notice
- Service Provider Name (SPN)
- That's HelloRoam you see up in your phone's status bar, not a mystery reseller name. The SPN is a standard field baked into every eSIM profile, and most travel eSIM resellers do not bother provisioning their own.
- Public Network Name (PNN)
- The PNN is the network name field in your eSIM profile, set out in 3GPP TS 31.102 (EF_PNN). Your phone can read it to show the name of the network you're connected to.
- Access Point Name (APN)
- Your HelloRoam eSIM sets its own Access Point Name automatically when it installs, so your mobile locks onto the strongest local network without you touching a single setting.
What you see is our standard retail pricing across 185+ countries, nothing marked up for the page you landed on. Plans get recommended off real traveller feedback and actual network performance, not guesswork. You can get a refund on unactivated eSIMs within 180 days.
