Audio & calls

Phone has no dial tone or ring when calling out

This is usually caused by no cellular signal, an app-based calling issue, or a carrier account problem rather than the phone itself. Checking signal and restarting the phone resolves most cases.

  • CommonCarrier network outageA regional outage can prevent all outgoing calls temporarily.

  • PossibleCarrier account issue such as a suspended lineBilling problems can disable calling while data or texting still work.
  • Less commonSoftware glitch in the phone or calling appA stuck process can block the dialer from initiating calls.

What to do

  1. Check the top of the screen for signal bars and confirm Airplane Mode is off.
  2. Restart the phone to refresh its connection to the cellular network.
  3. Remove and reinsert the SIM card to make sure it's seated correctly.
  4. Try calling from a different phone with the same SIM if possible, to isolate the phone versus the SIM or account.
  5. Check your carrier's website or app for outage alerts in your area.
  6. Confirm your account is in good standing and not suspended for billing reasons.
  7. Try dialing a different number, including an emergency test like 611 (carrier support), to see if any calls go through.
  8. If nothing changes after these steps, contact your carrier, since the issue is likely account or network related.

When to call a pro

If no calls go through after restarting and reseating the SIM, contact your carrier to check for an account or network problem.
