Message your Box on Signal

Link your Signal account to your Box, then message it from your phone through Note to Self, wherever you have internet.

Before you start

On a computer, the page shows a square code:

  2. Tap Settings, then Linked Devices, then +.
  3. Scan the code on your computer screen. Confirm if Signal asks.

On your phone, tap Open Signal & link box, confirm in Signal, then return to your browser.

The page shows Waiting for confirmation, then returns to Settings on its own. The Signal notifications card now shows your number with a linked tag.

Message your Box

  1. Open Signal on your phone.
  2. Open Note to Self. Search for it if you cannot see it.

If something goes wrong

  • Card says Add your home Wi-Fi above first: set up Wi-Fi. See Change Wi-Fi or move your Box.
  • Your previous link attempt was interrupted: click Try again.
  • Couldn't start Signal linking: reload the page.
  • Stuck on Waiting for confirmation: check you scanned the code, or tapped the button, in Signal, and that your phone has internet.
  • No reply in Note to Self: check the card shows your number as linked. If not, link again. If so, see Troubleshooting.
