What's Smartphone Mobile Hotspot (SMHS)?

  • Share your Internet connection with up to 10 devices.
  • While connected to SMHS, make and receive calls and texts on your phone.
  • SMHS on your device is different from location hotspots, like the Wi-Fi you connect to at a coffee shop or airport, and hotspot devices, like the devices sold by T-Mobile.


Additional details

  • For Simple Choice plans, once the high-speed data allotment has been reached, SMHS and on-device data speed is reduced to 2G speeds.
  • Simple Choice unlimited plans will have SMHS speeds reduced after using 14 GB of mobile hotspot data. In either case, your data won’t stop, you’ll experience slower speeds until the end of your billing cycle.
  • On all T-Mobile plans, during congestion, a small fraction of customers using >50GB/month may notice reduced speeds until the next bill cycle due to data prioritization.
