In the Signal messaging app, “Not Reachable” typically means that the app is unable to establish a connection with the recipient’s device. This status can occur for several reasons, including:
- Recipient’s Device is Offline
The recipient’s phone may be turned off, in airplane mode, or disconnected from the internet (Wi-Fi or mobile data). - Signal App is Not Running
If the Signal app is not active or has been force-closed on the recipient’s device, it may not be able to receive messages until reopened. - Temporary Network Issues
There could be temporary network problems on either the sender’s or recipient’s side, preventing communication. - Blocked or Unregistered Contact
If the recipient has blocked you or has unregistered their number from Signal, they may show as “Not Reachable.” - Server Issues
Occasionally, Signal’s servers may experience downtime or delays, affecting the delivery status of messages.
If you encounter this status, try these steps:
- Confirm that you and the recipient both have a stable internet connection.
- Check if Signal’s servers are operational (you can use tools like Downdetector).
- Verify that the recipient’s Signal app is active.
- Wait and try again later, as the issue may resolve itself.
This status is usually temporary and often resolves once the recipient’s device reconnects to the Signal network.
