30-second accurate test checklist
- Use cellular, not Wi-Fi. Confirm the 5G or 4G LTE icon is on and Wi-Fi is off.
- Check bars. Run the test with at least 2-3 bars; 1 bar will read low no matter what.
- Pause other data use. Close streaming, downloads, cloud backups, and hotspot sharing.
- Stay still. Testing while moving forces tower handoffs that skew results.
- Tap start. Open SwiftSpeedTest.com in your phone browser and run the test.
- Retest twice if needed. Average two or three runs in the same spot to smooth out network swings.
2025 mobile speed benchmarks to compare against
Use these ranges to judge whether your result is typical for your network type. Ping under 50 ms feels responsive for browsing and gaming.
| Network | Download (Mbps) | Upload (Mbps) | Notes |
|---|---|---|---|
| 4G LTE | 15-80+ | 5-20 | Can drop indoors; move toward windows. |
| 5G mid-band (most common) | 80-400+ | 15-60 | Best balance of speed and coverage. |
| 5G high-band/mmWave | 500-1000+ | 50-100 | Great speeds but only near the tower. |
What most often skews mobile results
Mobile networks swing more than home internet. Watch these variables so your numbers reflect the network, not testing noise.
- Signal strength and quality. Each bar you lose can shave off huge Mbps. Walls and elevators hit hardest.
- Network congestion. Stadiums, concerts, and rush-hour corridors slow everyone on the same tower.
- Data caps or deprioritization. Some plans slow after hitting a threshold. Check your account for fair-use limits.
- Device limits. Older phones may not support newer 5G bands or carrier aggregation that boosts speed.
- Hotspot or background use. Other devices or apps quietly eating bandwidth will drag down your test.
If your mobile speed test looks low, try this
- Toggle airplane mode on, wait 10 seconds, then off to force a fresh tower connection.
- Move outdoors or next to a window; retest to see the difference.
- Switch your phone to 5G Auto/On (or LTE if 5G is weak) and rerun.
- Pause hotspot sharing and large app downloads on the phone.
- Disable battery saver while testing; it can throttle radios.
- Restart the phone if speeds stay low in multiple spots.
- Try a different time of day to compare congestion levels.
- Run two back-to-back tests and average them to smooth spikes.
Still slow everywhere? Contact your carrier with screenshots of multiple tests; they can check for account throttles or local outages.
How to read your numbers
- Download Mbps: Impacts browsing and streaming. If you are above the ranges in the table, you are doing well for that network type.
- Upload Mbps: Matters for video calls, cloud backups, and social uploads. Under 5 Mbps can make calls choppy.
- Ping (ms): Under 50 ms feels snappy; under 30 ms is ideal for gaming.
- Stability: If one test is high and the next is low, congestion or weak signal is likely. Average two or three runs.
