Vietnam eSIM plans from eSpeedz start at $7.99 and connect to MobiFone and Vietnamobile, covering Hanoi, Ho Chi Minh City, Da Nang and the main travel routes in between. Your QR code arrives by email within minutes, you install it before departure, and the plan only starts once your phone connects to a network in Vietnam.
Vietnam runs on apps. Grab or Xanh SM for rides, Google Maps for the Old Quarter's tangle of streets, Google Translate for the menu. Land with all of it already working.
Most people don't do Vietnam in a long weekend. The classic route runs north to south over two or three weeks, from Hanoi and Ha Long Bay down through Hue and Hoi An to Ho Chi Minh City. Paying a US carrier's daily roaming fee for that whole stretch adds up to a lot of money for something you can sort out once, in advance, with a single prepaid plan.
Local SIMs are sold at kiosks in the arrivals halls at Noi Bai in Hanoi, Tan Son Nhat in Ho Chi Minh City and Da Nang. You'll need your original passport for registration, and airport prices tend to run higher than in town. If you'd rather walk straight out to the taxi rank, an eSIM installed at home saves that whole step.
Getting around is where data really earns its keep. Grab is everywhere, and Xanh SM, the all-electric taxi and motorbike service, has become a big player in Vietnamese cities. Gojek pulled out of Vietnam in September 2024, so older blog posts telling you to download it are out of date. Hotels and homestays are generous with wifi, and nearly every cafe has a password on the wall, but you'll be on mobile data in the back of a ride, on a sleeper train, or halfway around a mountain loop where the signal gets thin.

Vietnam is a heavy maps-and-rides destination, so budget a little more than you might elsewhere. A one-week city break in Hanoi or Saigon is comfortable on 3GB to 5GB. For the full two-week north-to-south trip with daily Grab rides, translation and photo sharing, 10GB is a good fit. Remote workers and anyone who streams on long bus and train rides should go for 20GB. Offline maps and downloading shows on hotel wifi stretch any plan further.
Vietnam is long and thin, so the weather depends on where you are. The north, including Hanoi and Ha Long Bay, is pleasant in spring and autumn and surprisingly cool from December to February. The central coast around Hoi An and Hue is at its best from roughly February to August and gets its heaviest rain in autumn. The south, including Ho Chi Minh City, the Mekong Delta and Phu Quoc, is dry from about December to April.
