Mobile Data Speed Guide
Understand 4G and 5G speed test results.
Mobile data speed depends on signal strength, tower load, frequency band, device support and location. Results can change quickly while moving.
5G can be very fast, but weak indoor signal or congestion can reduce performance.
Run tests in different rooms and near windows to find where your mobile router or phone performs best.
Quick checklist
- Run a fresh test after changing one setting.
- Compare Wi-Fi and Ethernet when possible.
- Check download, upload, ping and jitter together.
