T-Mobile Home Internet supports a maximum of 64 simultaneous Wi-Fi device connections. This T-Mobile home internet device limit applies to both the standard 5G Home Internet plan and the AWAY plan, meaning you can connect up to 64 devices at once on either service.
What is the T-Mobile home internet device limit?
The official maximum is 64 devices connected at the same time to your home Wi‑Fi network. This limit is documented for the standard T-Mobile Home Internet service and the AWAY plan. The gateway itself handles the connections, so you do not need to count devices manually, the system manages the 64-device capacity automatically.
How to view your connected devices
You can check which devices are currently connected using either the T-Life app or the gateway settings menu.
Using the T-Life app
- Open the T-Life app on your phone.
- From the Home screen, select the Internet shortcut at the top of the screen.
- Look for the client list or connected devices section to see all active connections.
Using the Sagemcom gateway settings
- Open a web browser and enter the gateway’s IP address to access its settings page.
- Go to Settings.
- Select Client list. This is labeled as “view connected devices” on the support page.
These paths work on both iPhone and Android devices.
How to connect a new device
- On the device you want to connect, go to its Wi‑Fi settings.
- Turn Wi‑Fi on.
- Select your T-Mobile Home Internet network name from the list of available networks.
- Enter the Wi‑Fi password when prompted.
Once connected, the device counts toward the 64-device limit.
Plan restrictions and data policies
5G Home Internet is an unlimited plan with no data cap. Home Internet Lite, however, uses data buckets of 100 GB or 150 GB per month. Home Internet Lite plans activated starting May 9, 2024 may only be used at the approved address and may be restricted away from that address. Rely Internet, Amplified Internet, and All-In Internet must use a home service address eligible for unlimited service and may be restricted away from the approved address.
Technical limitations to know
The HSI MTU size is set to 1500 across all gateways, and adjusting the MTU size is not supported. While you can connect up to 64 devices, the practical impact on network performance depends on what those devices are doing. Streaming video, online gaming, and large file downloads use more bandwidth than simple browsing or email. If you are concerned about T-Mobile Home Internet speed limits, the service delivers speeds based on your location and network conditions, but connecting many high-bandwidth devices at once can slow down each connection.
Frequently Asked Questions
Is the 64-device limit the same for all gateway models?
Yes. T-Mobile documents a 64-device limit across its Home Internet service, and no separate limit is specified for different gateway models.
Can I connect smart home devices like security cameras and thermostats?
Yes. T-Mobile Home Internet is compatible with a wide range of smart home devices, including security cameras, smart thermostats, and voice assistants. Each device counts toward the 64-device limit.
What factors affect performance when many devices are connected?
Performance depends on the bandwidth usage of individual devices, the type of online activities being conducted, and overall network congestion. Connecting many devices that stream video or download large files simultaneously can reduce speed for each connection.
Does the 64-device limit apply to wired Ethernet connections?
The documented 64-device limit applies to Wi‑Fi connections. Wired Ethernet connections to the gateway also count toward the total number of connected devices.
Can I exceed the 64-device limit?
No. The gateway is designed to support up to 64 devices at once. Attempting to connect more than 64 devices may result in some devices being unable to connect or experiencing poor performance.
