Smartphone Mobile HotSpot (tethering)

Smartphone Mobile HotSpot (SMHS) – also referred to as tethering – is a great way to securely share your smartphone’s Internet connection with your laptop, tablet, and other Wi-Fi-enabled devices on T-Mobile’s high-speed nationwide network.


How it works

SMHS is included with our Simple Choice™ and T-Mobile ONE™ plans.


If you have T-Mobile ONE, you get unlimited mobile hotspot speeds at up to 3G (512kbps). It’s great for web browsing, music streaming, and email, but it may not work well with all video streaming. For an additional cost, you can add T‑Mobile ONE Plus and get unlimited high-speed 4G LTE mobile hotspot and more. Read about T-Mobile ONE.


Things you should know about Smartphone Mobile HotSpot:

  • It only works in 4G and 4G LTE coverage. View our coverage map.
  • You can share your Internet connection with up to 10 devices. While connected, you can still make and receive calls and texts.
  • For the small fraction of customers using more than 50 GB per month, data usage must be on your smartphone.
  • For Simple Choice customers, once you reach your high-speed data allotment, your SMHS (and on-device) data speed is reduced to 2G speeds. Customers with a Simple Choice unlimited plan will have their SMHS speeds reduced after using 14 GB of mobile hotspot data. In either case, your data won’t stop — you’ll just experience slower speeds until the end of your billing cycle.
  • If you're on an older Simple Choice Plan, you'll need to add 500 MB of data. There's no additional charge. Learn how to change your services.
  • On all T-Mobile plans, during congestion, the small fraction of customers using more than 50 GB per month may notice reduced speeds until next bill cycle due to data prioritization. Smartphone/tablet usage is also prioritized over tethering usage, which may result in higher speeds for data used on your smartphone or tablet.
  • If you're having issues connecting your game systems, TVs, or other devices to your Smartphone Mobile HotSpot, contact your device manufacturer for support.
