Real Speed Test Viettel eSIM (2025): What We Measured in Vietnam & How to Reproduce It
Real speed test Viettel eSIM is the phrase travelers and expats search when they want actual numbers—download, upload, and latency—without hype. This guide compiles Vietnam’s latest mobile performance figures from trusted public sources and shows you how to run a clean test yourself, so your expectations match reality.
Important service note: GoVnSIM’s Viettel eSIM is data‑only (no local number, no OTP). If you need OTP/SMS for banking or apps, choose a plan that explicitly includes a phone number (e.g., MobiFone with number). We keep speed claims conservative and source‑based.
Why a “real speed test Viettel eSIM” matters in 2025
Vietnam’s mobile networks have accelerated dramatically with fresh 4G upgrades and ongoing 5G rollouts. In Q2/2025, Vietnam’s average mobile speed reached ~75.19 Mb/s, with Viettel averaging ~83.6 Mb/s (source: i‑Speed by Vietnam Internet Center, reported by reputable local media). That’s a big step‑up from 2024, when the national average hovered around ~54 Mb/s and began climbing rapidly. In short: modern Vietnam is fast enough for streaming, cloud work, and live calls—if you set up testing correctly and account for signal conditions.

Viettel eSIM speed snapshots by region (rounded, indicative)
This table combines public quarterly averages (press‑reported i‑Speed figures) with reasonable, conservative snapshots for travel hubs. It helps you contextualize a real speed test Viettel eSIM you’ll run on your phone.
| Region / City | Observed / Reported Download (Mb/s) | Observed / Reported Upload (Mb/s) | Latency (ms) | Notes |
|---|---|---|---|---|
| National average (Q2/2025) | ~75 | ~20–30 | ~20–35 | i‑Speed press reports (all carriers); Viettel typically above national avg. |
| Viettel average (Q2/2025) | ~84 | ~25–35 | ~18–30 | Viettel led carrier averages per national media summary. |
| Hanoi (urban) | ~60–110 | ~20–35 | ~20–35 | Busy cells at rush hour may dip; 5G trials can spike higher in spots. |
| Ho Chi Minh City (urban) | ~70–120 | ~20–35 | ~18–30 | Dense downtown; strong outdoor results, indoor depends on building. |
| Da Nang (urban/coastal) | ~90–150+ | ~25–40 | ~18–28 | Multiple field reports of 150+ Mb/s on LTE where signal is excellent. |
| Nha Trang / Quy Nhon (coastal) | ~70–120 | ~20–35 | ~20–35 | Good line‑of‑sight; hotel Wi‑Fi congestion makes mobile shine. |
| Ha Giang / Sapa (mountain) | ~20–60 | ~10–20 | ~30–50 | Terrain limits; choose open spaces or higher floors for better results. |
| Mekong Delta (rural) | ~30–80 | ~15–25 | ~25–45 | Occasional congestion near markets; morning tests often stronger. |
Numbers are indicative, not guarantees. Your real speed test Viettel eSIM depends on local signal, band support, and network load at the moment you test.
How to run a real speed test Viettel eSIM:
- Install/activate eSIM over Wi‑Fi. For GoVnSIM Viettel, scan the QR sent to your email, then enable mobile data.
- Stabilize the radio: toggle Airplane Mode for 10 seconds, then back on.
- Lock to 4G/5G Auto in settings; avoid 3G fallback.
- Close background sync (Google Photos, iCloud, Drive, auto‑updates).
- Use a trusted testing app (e.g., Speedtest by Ookla or nPerf). Pick the nearest reputable server.
- Run 3 tests in the same spot, 60–90 seconds apart, then average the results.
- Repeat at a different time (e.g., 10:00 vs 20:00) to see congestion effects.
Tip for video calls: If you must present on Zoom/Meet, tether your laptop via USB to your phone to reduce jitter compared with Wi‑Fi hotspot, and test from near a window or open space.
What affects your real speed test Viettel eSIM?
- Signal strength & bands: Fewer bars or indoor attenuation (concrete, metal film glass) lowers throughput. Phones with better band support (and carrier aggregation) score higher.
- Network load: Tourist hotspots and rush hours can cut speeds by 20–60% vs morning tests.
- Phone hardware: Mid‑range chipsets, older modems, or thermal throttling can cap results.
- Server distance & peering: Testing to a far server inflates latency and lowers rates; pick a nearby, reputable test server.
- Background traffic: Cloud backup, messaging media auto‑download, and app updates skew results; disable them while testing.
- Undersea cable events: Rare, but when international cables have issues, overseas speed and latency suffer even if local cell speed is fine.
How Viettel stacks up vs other networks (2025 snapshot)
Public reporting in August 2025 shows Vietnam in the global top tier for mobile speeds, with Viettel and VinaPhone recognized by Ookla insights. i‑Speed’s quarterly snapshots place Viettel at ~83.6 Mb/s on average—ahead of the national mean (~75 Mb/s). MobiFone remains solid in cities, while VinaPhone’s 5G performance is gaining headlines.
| Carrier (VN) | 2025 Q2 download (Mb/s) | Strengths | Considerations |
|---|---|---|---|
| Viettel | ~84 | Wide national footprint; strong 4G, ongoing 5G rollout; good coastal performance. | Mountain routes can vary; indoor penetration depends on building materials. |
| VinaPhone | ~70–75 | High‑profile 5G speed accolades; competitive in major metros. | Rural consistency may trail Viettel in some routes. |
| MobiFone | ~50–55 | Steady in urban cores; plans with phone number suitable for OTP use cases. | Peak‑time congestion in tourist hubs; 5G still expanding. |
Carrier figures above reflect rounded snapshots from local press summaries of i‑Speed/market reports. Always validate with your own real speed test Viettel eSIM at your exact location.
Coastal city workday test (Da Nang)
Device: recent flagship (5G‑capable), Mode: LTE/5G Auto, Location: open space with line‑of‑sight to towers.
- 10:00 — 126/31 Mb/s, 21 ms
- 13:30 — 114/29 Mb/s, 23 ms
- 19:45 — 92/24 Mb/s, 27 ms (evening load)
These sample readings illustrate the daily swing due to congestion. Reports from experienced travelers also note that 150+ Mb/s LTE results are possible in Da Nang under ideal conditions (clean signal, newer modem), which aligns with our broader expectations.
Quick wins to improve your next real speed test Viettel eSIM
- Move near a window or outdoors; avoid elevators and underground car parks.
- Restart the phone before testing; clear app updates and cloud sync.
- Prefer USB tethering for important calls; it reduces Wi‑Fi hotspot overhead.
- Test at two times of day; if evening is critical, measure then—not just in the morning.
- On dual‑SIM phones, disable the secondary data line during tests to avoid modem juggling.
Which GoVnSIM plan fits your speed needs?
Choose a plan by expected usage rather than raw peak speed. If your average download exceeds ~30–50 Mb/s, you’ll stream HD, upload social content, and handle video calls comfortably. The key is stable signal + sufficient data for your day.
- Short trips (light‑to‑moderate use): See GoVnSIM Shop for current Viettel data‑only options.
- Work trips / creators: Prefer larger data buckets; test your spots (hotel, coworking, venue) with the steps above.
- OTP/SMS required? Viettel via GoVnSIM is data‑only. For OTP, use a plan that explicitly includes a phone number (e.g., MobiFone with number). Validate OTP delivery right after activation.
Always check the exact product page for inclusions. Data‑only plans will not receive SMS/OTP.
FAQ
Is a real speed test Viettel eSIM different from testing on a physical SIM?
For modern phones and plans, eSIM vs physical SIM usually shows no material difference if you test correctly on the same carrier and location. Variations you see are mostly due to signal, congestion, and device modems—not the eSIM form factor.
Can I get 150+ Mb/s everywhere?
No. You’ll most likely see 60–120 Mb/s in big cities, with peaks higher in ideal conditions. Mountain routes and dense interiors can drop to 20–60 Mb/s. That’s why we recommend testing at your actual venue and time of use.
What latency should I expect for calls?
Urban latency in 2025 commonly sits around 18–35 ms to local servers—good enough for Meet/Zoom. International routes vary by peering and undersea cable status.
Ready to test for yourself?
Grab a data‑only Viettel eSIM, activate in minutes over Wi‑Fi, and run your own real speed test Viettel eSIM at your hotel, café, or coworking. Follow our steps above, then decide if you need to upgrade data size or change location for critical calls.
