Where 5G Actually Works in Ho Chi Minh City (2026)

Viettel launched its 5G network commercially in 2024 and now claims availability in all 63 provinces. In Ho Chi Minh City, Viettel's 5G is strongest in District 1, the Thu Thiem area of District 2, Phu My Hung in District 7, at Tan Son Nhat International Airport, and around major landmarks like the Bitexco Financial Tower and Nguyen Hue Walking Street. Based on their published coverage, these are the areas where you can expect a steady 5G signal outdoors.

Vinaphone's 5G covers similar urban zones but with a slightly smaller outdoor footprint. Their official map shows reliable 5G along main arteries such as Nguyen Hue, Le Loi, and Dong Khoi, as well as in District 7’s Korean quarter. Mobifone has the most limited 5G presence – it's mainly active near their headquarters and a handful of hotspots. For travelers seeking consistent 5G in 2026, we recommend sticking with Viettel or Vinaphone.

District 1 is the best-served area for 5G in HCMC. Ben Thanh Market, Nguyen Hue Walking Street, and the Bitexco Financial Tower all have strong 5G from both Viettel and Vinaphone. District 7’s Phu My Hung area, including Korean town and Crescent Mall, also enjoys excellent 5G coverage from both carriers. In District 2, the Thu Thiem new urban area has Viettel 5G available, but Vinaphone's signal can be spotty there.

At Tan Son Nhat International Airport, both Viettel and Vinaphone provide 5G in the domestic and international terminals. For other districts such as 3, 4, 5, and 10, 5G is inconsistent – you may pick it up in some open spots but drop back to 4G frequently. A general note: 5G signals struggle to penetrate buildings, so inside malls, hotels, and concrete structures you will likely fall back to 4G, which remains very stable throughout the city.

To use 5G in Vietnam, your phone must be 5G-compatible. For iPhones, that means iPhone 12 or newer. For Samsung Galaxy, models from the S20 series onward (excluding US Snapdragon versions that have regional restrictions) work. Google Pixel 5 and newer devices also support 5G. What you don’t need is a special “5G eSIM” – all our Viettel and Vinaphone eSIMs with 5GB/day or higher data include 5G access by default at no extra cost.

There are no specific settings to worry about. After you install the eSIM via QR code and activate it when you land in Vietnam, the phone will automatically connect to 5G in covered areas. One exception: mainland Chinese iPhones (including Hong Kong and Macau models) lack eSIM support entirely, so 5G eSIM is impossible on those devices – you would need a physical SIM or an alternate solution. For everyone else, the process is straightforward.

When you do get 5G in HCMC, typical download speeds range from 100 to 300 Mbps, with carriers advertising peaks up to 1 Gbps. Meanwhile, 4G LTE averages between 20 and 40 Mbps – plenty for video calls, Google Maps navigation, social media feeds, and even streaming video. For latency, 5G is under 20 milliseconds, while 4G is still a respectable 30–50 ms. That difference matters for real-time mobile gaming but not for typical traveler activities.

The main trade-off with 5G is battery drain. Because 5G modems consume more power, you might want to keep 5G enabled only when you need faster downloads and rely on 4G the rest of the time to stretch battery life. Our verdict: 5G is a bonus, not a necessity. Your trip will run smoothly on 4G alone – maps, messaging, and ride-hailing apps all work without issue.

For the widest 5G coverage in Ho Chi Minh City, choose a Viettel eSIM – its network covers more districts and has stronger signals in the key tourist and business areas. Vinaphone is a close second, especially in District 1 and District 7. Regardless of which carrier you pick, download offline maps (Google Maps and Grab) before you arrive; even though data works well, offline maps provide a reliable backup.

If your phone supports dual SIM, keep your home SIM active for SMS and calls while using the eSIM strictly for data – both 5G and 4G work fine in this setup. For trips longer than 15 days, consider a Viettel 15-day or 30-day plan, as those offer consistent speeds and generous daily data caps, ideal for extended stays without worrying about top-ups.
