eSIM Travel Tips for Vietnam
Grab Vietnam is essential from the moment you land
Grab operates across Vietnam and is the safest and most reliable way to get around Ho Chi Minh City and Hanoi. Taxi scams at Tan Son Nhat and Noi Bai airports are a known issue for tourists. Having Grab ready on your HelloRoam eSIM from the moment you clear customs protects you from airport taxi touts.
HCMC and Hanoi: very different cities, both worth visiting
Ho Chi Minh City is fast-paced, modern, and full of energy. Hanoi is older, more traditional, and quieter. Many Singapore travellers do a north-to-south or south-to-north trip. Both cities have excellent 4G on Viettel and MobiFone. Your HelloRoam eSIM covers the whole country as you travel the length of Vietnam.
Hoi An and Da Nang: popular SG beach and heritage stop
Da Nang and Hoi An are among the most popular Vietnamese destinations for Singapore visitors. The Ancient Town of Hoi An and My Khe Beach in Da Nang have solid 4G coverage. Scoot flies direct from Changi to Da Nang. Sort your HelloRoam eSIM before you board.
Ha Long Bay cruises: limited signal on the water
Ha Long Bay is one of Vietnam's most iconic destinations and a popular side trip from Hanoi. Signal is good in Ha Long city and on the bay during the day near islands, but overnight cruises on more remote parts of the bay drop signal. Download your cruise itinerary and photos before boarding.
Vietnamese SIM registration: a HelloRoam eSIM avoids the hassle
Local Vietnamese SIMs require passport registration at shops or kiosks. This takes time after a long flight from Changi. A HelloRoam eSIM skips all of this. Scan the QR code at home, activate on landing at Tan Son Nhat, and Grab is ready immediately.
Mobile networks in Vietnam: what Singapore visitors need to know
HelloRoam connects on Viettel Mobile and Vinaphone in Vietnam. Viettel is the largest operator with wide national coverage. Vinaphone is strong in urban areas and tourist destinations. Your eSIM picks the stronger signal automatically as you travel from Ho Chi Minh City to Hoi An to Hanoi.

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!!

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.
