All carriers that allow signal boosters on their networks must have customers register their locations. 

Register or update your booster

You'll need your account number (located on your T-Mobile bill) and your device information. If you're unable to locate it, check the user manual. Register your device if you have recently:


Why we need to register your booster

  • T-Mobile needs the registration to locate the addresses of signal boosters and, if necessary, to contact the owners.
  • This ensures signal boosters don't interfere with cellular coverage. Our engineers can use the information to resolve network problems in your area.
  • The FCC mandates signal boosters to be registered for this reason. Read more at:​.
  • Any information you provide us is subject to T-Mobile's Privacy Policy.
