Wi-Fi, cellular & Bluetooth

Phone has data but can't make or receive calls

This usually points to a VoLTE setting, a carrier-side voice service issue, or a call forwarding misconfiguration rather than a hardware fault. Checking voice-specific settings resolves most cases.

Symptoms

  • Internet and apps work fine over cellular data
  • Calls fail to connect, ring endlessly, or go straight to voicemail
  • Texts may or may not also be affected
  • Wi-Fi Calling works but cellular calls don't

Likely causes

  • CommonVoLTE or HD Voice setting disabled or misconfiguredSome networks require this specific voice setting to be enabled for calls to work over their newer network technology.
  • CommonCall forwarding accidentally enabled to an invalid or unreachable numberCalls can silently fail if forwarded somewhere that doesn't answer or doesn't exist.
  • PossibleCarrier-side voice service outage or account issueA billing problem or network fault could disable calling specifically while data continues working.
  • PossibleDo Not Disturb blocking all incoming callsThis would explain missed or unanswered calls specifically while data-based features work.
  • Less commonSIM card issue affecting voice services specificallySome SIM faults can affect voice registration while data authentication still works.

What to do

  1. Check Settings > Cellular > Cellular Data Options and confirm VoLTE (or equivalent) is enabled.
  2. Check Settings > Phone > Call Forwarding and confirm it's off or pointed to a valid number.
  3. Check Do Not Disturb or Focus mode settings for call restrictions.
  4. Try making a call over Wi-Fi Calling to see if the issue is specific to the cellular voice channel.
  5. Toggle Airplane Mode on and off, and restart the phone.
  6. Remove and reinsert the SIM card.
  7. Check your carrier account for any alerts specific to voice service.
  8. If calls remain broken while data works fine after these checks, contact your carrier to check voice service on your line.

When to call a pro

If data works but calls remain broken after checking VoLTE, forwarding, and Do Not Disturb settings, contact your carrier to check voice service on your account.
