Troubleshooting Steps
1. Check status.signal.org
Signal's official status page covers messaging, calling, registration, and storage service. When Signal has a major outage, the page is updated. If all systems show green but Signal isn't working, the issue is likely local.
2. Force-close and reopen Signal
On mobile, completely close Signal (not just minimize) and reopen it. This reconnects the WebSocket connection to Signal's servers. Many temporary connectivity issues resolve with a fresh connection.
3. Check background app permissions
On iOS: Settings → Signal → Background App Refresh → Enable. On Android: Battery settings → Signal → Unrestricted. Signal cannot receive messages when the app is in the background without these permissions.
4. Try Signal's censorship circumvention
If Signal is blocked in your region: Signal Settings → Privacy → Advanced → Censorship Circumvention. This enables domain fronting to bypass network-level blocks. Also try connecting via VPN.
5. Re-register if sync fails
If Signal Desktop or a new device can't sync, try unlinking and relinking: Signal Desktop → Preferences → Linked Devices → Remove device, then re-scan the QR code from the mobile app.
Frequently Asked Questions
Is Signal down right now?
To check if Signal is down, visit status.signal.org for the official Signal status page. You can also check APIStatusCheck.com/is-signal-down or DownDetector for user-reported issues. Signs Signal is down: messages show a single check mark but don't deliver, calls fail to connect, or the app is unable to register your phone number.
Why are my Signal messages not delivering?
Signal message delivery failures can be caused by: (1) Signal server outage — check status.signal.org, (2) Recipient's phone is offline or without data, (3) Your or the recipient's Signal registration has expired — re-register, (4) A network or firewall blocking Signal's servers, (5) Background app refresh is disabled on iOS — Signal can't receive messages in background without it. Signal uses end-to-end encrypted sealed sender delivery, so messages must fully deliver or fail — there is no partial delivery.
Why is Signal unable to register my phone number?
Signal registration failures are typically caused by: (1) SMS delivery issues — if the verification code isn't arriving, try the voice call option, (2) VoIP numbers are not supported by Signal for registration — use a real mobile number, (3) Your country blocks Signal registration — use a VPN with a supported country's IP, (4) You've re-registered too many times — Signal has a rate limit on registration attempts, (5) Signal servers are temporarily overloaded during a surge (e.g., after a WhatsApp outage or data breach drives users to Signal).
Does Signal work in all countries?
Signal is blocked in several countries including China, Iran, Cuba, UAE, and others. Signal has a built-in censorship circumvention feature called "censorship circumvention" (under Privacy settings) that routes traffic through domain fronting to bypass blocks. If that doesn't work, a VPN with servers in an unblocked country is required. Signal's open-source nature means blocking it requires blocking its entire infrastructure, which some governments attempt.
How is Signal different from Telegram for privacy?
Signal and Telegram both offer messaging but differ significantly in privacy: Signal encrypts ALL messages end-to-end by default using the Signal Protocol (which Telegram also uses for secret chats, but NOT regular chats). Telegram stores regular chats on its servers and can decrypt them. Signal is a nonprofit (Signal Foundation) with no advertising revenue model. Signal's source code is fully audited. For privacy-critical communications, Signal is the stronger choice. Telegram's advantages are better bots, channels, file sharing limits, and broader feature set.
