🧭 How to Run a Real Speed Test Viettel eSIM
- Activate your Viettel eSIM from GoVnSIM over Wi-Fi by scanning the QR code sent to your email.
- Toggle Airplane Mode ON for 10 seconds, then OFF to refresh network registration.
- Lock to 4G/5G Auto; avoid 3G fallback in your settings.
- Close background sync apps (Photos, Drive, iCloud, Updates).
- Use Speedtest by Ookla or nPerf and select a nearby trusted server.
- Run three tests 60–90 seconds apart; average the results for consistency.
- Repeat later in the evening to observe network congestion differences.
Pro tip: For Zoom or Google Meet calls, tether your laptop via USB instead of hotspot. It reduces jitter and ensures higher sustained upload speed.
📶 What Affects Your Real Speed Test
- Signal strength: Bars and placement matter. Move near a window or balcony for better throughput.
- Network load: Tourist areas and rush hours can slow results by 20–60%.
- Hardware: Newer modems (Snapdragon 8-series, Apple A15+) sustain faster 5G aggregation.
- Server distance: Testing to far-away servers inflates latency.
- Background traffic: Pause backups, messaging auto-downloads, and updates.
- Undersea cables: Rare outages can reduce international speeds but not local cell performance.
📈 Viettel vs Other Carriers (2025 Snapshot)
| Carrier | Q2/2025 Avg (Mb/s) | Strengths | Considerations |
|---|---|---|---|
| Viettel | ~84 | Nationwide coverage; fast 4G, wide 5G rollout | Mountain routes vary; indoor walls may affect signal |
| VinaPhone | ~70–75 | High 5G peak speeds in cities | Less stable in rural provinces |
| MobiFone | ~50–55 | Good for OTP-enabled plans | 5G still expanding; mild congestion in hubs |
📍 Field Test Example – Da Nang, July 2025
Device: 5G-capable flagship, Mode: LTE/5G Auto, Line of sight to tower.
- 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 drops show normal congestion, not faults. Under ideal signal, 150+ Mb/s LTE has been recorded in Da Nang — consistent with Viettel’s strong coastal infrastructure.
⚡ Quick Wins to Improve Your Speed
- Restart before testing; clear background apps.
- Move near windows or outdoors for cleaner signal paths.
- Disable secondary SIM data during tests on dual-SIM phones.
- Use USB tethering for important calls instead of Wi-Fi hotspot.
- Run tests at different times (morning vs evening) to gauge consistency.
