What These Síminn Results Mean

Best Use Case

Síminn is well suited to gaming, video calls, remote work, and heavy cloud use because its benchmark combines low ping with strong upload speed.

Upload Profile

Upload is moderate relative to download. It should be enough for everyday calls and file sharing, but heavy creators may want a higher tier.

Technology Notes

Síminn uses Fibre (FTTH), Cable, 5G. Technology affects upload symmetry, latency, evening congestion, and how close you can get to advertised plan speeds.

Síminn vs Iceland Broadband Benchmarks

Use this comparison to separate provider performance from the wider market. A result below your plan speed may still be normal for your connection type, but a wired test far below both your plan and the country benchmark deserves troubleshooting.

Metric	Síminn	Iceland median	Interpretation
Download	156 Mbps	215.3 Mbps	Below the national median benchmark; plan mix or access technology may explain the gap.
Upload	94 Mbps	192.1 Mbps	Upload trails the country median, which may affect calls, backups, and creator workflows.
Ping	8 ms	5 ms	Latency is higher than the country median; test over Ethernet before blaming the ISP.

How to Run a Síminn Speed Test

Connect via Ethernet - For the most accurate baseline, connect your device directly to your router or modem with an Ethernet cable. Wi-Fi introduces variables that can mask your true plan speed. See our accuracy guide for full tips.
Close background apps - Pause streaming, downloads, and backups. Other devices on your network also consume bandwidth.
Start the speed test - Click GO on our homepage. The test measures download, upload, ping, and jitter in about 30 seconds.
Compare your result - Check your measured speeds against the typical Síminn results above. If you're significantly below your plan speed, review the common issues section below or contact Síminn support.
