HCMC Coverage (2025 Guide)

Reliable connectivity is essential for anyone visiting or living in Ho Chi Minh City. This guide explores HCMC coverage across Viettel, MobiFone, and VinaPhone, including updated 4G/5G speed tests, coverage maps, and real-life user case studies. We also compare physical SIMs with modern eSIM options for the best experience in 2025.

📶 Overview of HCMC Coverage

Ho Chi Minh City (HCMC) has one of the strongest mobile network infrastructures in Vietnam. All three major carriers — Viettel, MobiFone, and VinaPhone — offer 4G LTE and expanding 5G service. In 2025, travelers and locals can expect:

• 4G speeds ranging from 35–60 Mbps in central districts.
• 5G speeds up to 220 Mbps in selected downtown areas.
• Reliable signal across Districts 1, 3, 5, 7, and Thủ Đức.
• Improving suburban coverage, though performance may dip in rural edges.

📊 Network Speed Tests (2025)

Independent February 2025 speed tests in District 1, 3, and 7 show the following results:

• Viettel: 4G average 52 Mbps, 5G up to 220 Mbps.
• MobiFone: 4G average 46 Mbps, 5G ~200 Mbps near Nguyễn Huệ.
• VinaPhone: 4G ~41 Mbps, 5G ~180 Mbps in commercial districts.

These results indicate that while all networks are suitable for video streaming, navigation, and messaging, Viettel performs slightly better for suburban and out-of-city trips.

🏙️ Coverage by District

Coverage in Ho Chi Minh varies slightly depending on the district:

• District 1: All carriers strong, 5G available near Nguyễn Huệ and Bến Thành.
• District 3: Consistent 4G/5G speeds with MobiFone performing well.
• District 7: Good 4G coverage, 5G still expanding.
• Thủ Đức: Viettel stronger in university and residential zones.
• Củ Chi & outskirts: Only Viettel maintains reliable 4G coverage.

📱 eSIM Options with Reliable HCMC Coverage

For visitors, eSIMs are the simplest way to ensure strong coverage across Ho Chi Minh. Recommended options include:

• Vietnam eSIM 30 Days – 6GB/day (MobiFone, includes local number and 500 minutes calls).
• Vietnam eSIM 20 Days – 4GB/day (MobiFone, instant QR delivery, auto-activation).
• Vietnam eSIM with Phone Number (3GB/day, OTP-ready, includes local calls, 10–30 days).
• Viettel eSIM (15–30 days, 5GB/day, best for trips beyond HCMC).

These plans provide hotspot/tethering support, making them ideal for sharing internet with laptops and tablets.

📊 Case Study: Travelers Using Different Networks

In March 2025, three travelers tested networks in Ho Chi Minh:

• Maria (Spain): Used MobiFone eSIM 20 Days – 4GB/day. Reported average speeds of 48 Mbps in District 1. Had minor slowdowns in District 7.
• David (UK): Activated Viettel eSIM. Noticed consistently higher speeds outside HCMC (80 Mbps 4G in Mekong Delta).
• Lin (Taiwan): Bought Vietnam eSIM with Phone Number for 15 days. Found OTPs essential for Grab and banking. Speeds around 40 Mbps downtown.

Result: All three networks were sufficient, but Viettel showed stronger performance beyond city limits.

📝 Practical Tips for Ensuring Good Coverage

• Check if your phone supports Vietnamese 4G/5G bands (LTE Band 3/7/8, 5G n78).
• Choose Viettel if traveling outside HCMC — best rural coverage.
• Use MobiFone for strong speeds in District 1 and central business areas.
• VinaPhone is a good option for short-term trips focused on urban districts.
• Always verify if your plan resets data daily or is a one-time allowance.
