In brief

Test wired to the gateway or right next to it, at a few times of day, and check signal in the T-Mobile Internet app before blaming the plan. Use our speed test. T-Mobile lists typical downloads of 170 to 354 Mbps on Rely (capped at 354) and 170 to 498 Mbps on Amplified and All-In, with uploads of 12 to 55 Mbps.

From T-Mobile's plan pages and Broadband Facts labels. T-Mobile says 25% of customers see speeds below these ranges and 25% above. Rely's 354 Mbps cap applies to customers who joined from June 2026.

If you're on Rely and your tests sit right at about 350 Mbps, you've hit the plan cap, not a signal problem. Amplified and All-In also come with T-Mobile's newer Wi-Fi 7 gateway.

For most households that stream, browse and work from home, T-Mobile’s typical speeds are plenty. The weak points are uploads and evening consistency. Compare plans in Rely vs. Amplified vs. All-In, and against satellite in Starlink vs. T-Mobile Home Internet.

Why 5G home speeds vary

Your gateway shares a cell tower with phones in the area, and its speed depends on signal strength, distance to the tower and how busy the tower is. Two homes on the same street can get very different results.

Where to put the gateway

  • Near a window, on the side of the home facing the nearest tower.
  • On a higher floor, off the floor and away from metal, mirrors and appliances.
  • Use the T-Mobile Internet app to check signal in each spot before you settle on one.

How to run an accurate test

  • Plug a computer into the gateway's Ethernet port, or test right next to it.
  • Test three times: morning, afternoon and evening.
  • Note the signal bars in the app each time, so you can tell a signal problem from a busy tower.

Busy hours

T-Mobile can slow home internet traffic when a tower is busy, so evening results are often lower. If speeds are fine in the morning and drop every evening, that's congestion, not your equipment.

If your speeds are low

Restart the gateway, move it, and test again. See why T-Mobile Home Internet is slow for more fixes. If signal stays weak, compare other 5G home internet plans on a different network, such as Visible Home Internet on Verizon ($30/mo with a Visible line), or see what else reaches your address.
