  • Also listed: PO Box 53410, Bellevue, WA 98015-3410.

Getting Help Without a Call

  • T-Life app: manage your account, pay your bill and chat with an agent. The app's gateway placement assistant helps fix weak signal.
  • Signal first: most Home Internet speed problems come down to where the gateway sits. T-Mobile suggests putting it near a window and away from obstructions.

Cancelling or Returning Equipment

  • Test Drive: cancel within the first 15 days for a one-time bill credit.
  • Returns: after cancelling, return the gateway within 45 days to avoid a non-return fee of up to $370.

Moving

Check that 5G Home Internet is available at your new address. Then call 1-855-545-5021 to update your address, take the gateway with you and self-install it.
