eSIM Travel Tips for Vietnam
Grab app and live navigation
Grab (Southeast Asia's ride-sharing equivalent of Uber) is essential in Vietnamese cities. You need a live data connection to book Grab rides from Ho Chi Minh City's Ben Thanh Market or navigate Hanoi's Old Quarter. Your HelloRoam eSIM keeps Grab and Google Maps running throughout your trip.
Coverage on the motorbike trails
The Ho Chi Minh road, the Hai Van Pass, and the mountain roads around Sapa and Ha Giang are popular with Australians on motorbike tours. Coverage on these routes can be patchy in the mountains. Download offline maps for any extended mountain riding.
Ha Long Bay and island coverage
Ha Long Bay cruise boats typically provide Wi-Fi on board but the signal is inconsistent. On the water between limestone karsts, mobile coverage can drop. Download any content you need before boarding your cruise and enjoy the scenery without needing data.
Vietnamese food navigation
The best Vietnamese food is often in unmarked alley restaurants found only through local recommendations and Google Maps reviews. A live data connection is essential for finding pho spots, banh mi stalls, and fresh spring roll restaurants that do not appear on tourist maps.
Currency and banking apps
Vietnam is still largely cash-based. ATMs are widely available in cities. Keep your Australian banking app accessible on mobile data to monitor your account when withdrawing Vietnamese Dong. Check smartraveller.gov.au before visiting Vietnam.
Mobile networks in Vietnam: Viettel, Vinaphone, and Mobifone
Vietnam's three main carriers are Viettel, Vinaphone, and Mobifone, all state-controlled. Viettel's network stretches into the countryside, the northern highlands, and the Mekong Delta, while Vinaphone is strong in the major cities. Your HelloRoam eSIM connects on Vinaphone and Viettel and uses whichever signal is stronger where you are, with 5G now live in the biggest cities.
