Test your T-Mobile connection speed below

Run this free T-Mobile speed test to check your T-Mobile 5G Home Internet connection. You will get download speed, upload speed, ping, and jitter in under a minute.
T-Mobile Home Internet runs over the 5G cellular network, so your speed depends heavily on signal strength, gateway placement, tower distance, and how many users are on the tower. Typical results range from 100 to 400+ Mbps download.
Gateway placement is everything. Use the T-Mobile Internet app’s placement assistant to find the spot with the strongest signal — usually near a window on the side of your home facing the nearest tower, and away from metal appliances.
Test in a few different spots and keep the gateway where results are consistently best. Avoid placing it in basements, closets, or behind TVs.
Wireless speeds naturally fluctuate with tower congestion, weather, and signal obstructions. It is normal for T-Mobile Home Internet to be faster late at night and slower during evening peak hours.
If speeds drop suddenly, check the gateway’s signal bars in the app and restart the gateway. Persistent slowdowns at all hours may mean tower maintenance or deprioritization during congestion.
For the most accurate result, connect your computer directly to your router with an Ethernet cable if possible. If you must use Wi-Fi, stand close to the router and disconnect other devices during the test.
Close streaming apps, cloud backups, and other browser tabs before clicking Start. Run the test 2–3 times at different times of day — speeds often dip during evening peak hours (7–11 PM) when many households are online.
Download speed (Mbps) controls how fast you can stream, browse, and download files. Upload speed (Mbps) affects video calls, live streaming, and cloud backups. Ping (ms) measures responsiveness — under 50 ms is good for gaming and calls. Jitter (ms) measures consistency — lower is better, especially for voice and video.
Compare your download result to your plan’s advertised speed. Most providers advertise “up to” speeds, so a result within about 20% of the advertised rate is normal.
T-Mobile advertises typical speeds of 100–400+ Mbps download. Anything consistently above 100 Mbps handles HD streaming, video calls, and gaming for most households.
