If you recently noticed that calls from new or unknown numbers never reach your OnePlus 13, the issue is likely caused by call blocking settings, app permissions, or carrier restrictions. It can also happen if the phone’s spam filter is too strict or if the SIM card has temporary registration issues.
Whatever the reason, this guide will help you identify and fix why your OnePlus 13 is not receiving calls from new numbers.
Why Your OnePlus 13 Cannot Receive Calls from New Numbers
- Blocked numbers or call filter settings are preventing new callers.
- Third-party dialer or call recording apps are interfering with incoming calls.
- SIM card registration or carrier signal issues.
- Do Not Disturb or Focus Mode is active.
- Outdated software or corrupted network configuration.
Check the Blocked Numbers List.
Your phone may be automatically blocking new numbers. The built-in dialer can silently reject calls if the number appears as unknown or is flagged as spam.
- Open the Phone app, and then tap the three-dot icon in the top-right corner.
- Tap Settings, and then select Blocked numbers.
Remove any numbers that should not be there. Also, toggle off Block calls from unknown numbers if it is enabled.
Turn Off Do Not Disturb Mode.
Do Not Disturb (DND) blocks all calls except from contacts or favorites, which may explain why only new numbers cannot reach you.
- Open Settings, and then tap Notifications.
- Tap Do Not Disturb, and then toggle it off.
If you need DND on, check the Allowed calls section and make sure Calls from anyone is selected.
Check the Phone App Permissions.
If the dialer or calling app has restricted permissions, new calls may fail to come through properly.
- Open Settings, and then tap Apps.
- Tap Phone, and then tap Permissions.
Ensure Phone and Notifications permissions are allowed. Restart your OnePlus 13 afterward.
Reset Network Settings.
If your SIM is fine but the phone still cannot receive calls, network settings might be the problem. Resetting them can fix signal and registration conflicts.
- Open Settings, and then tap System.
- Tap Reset options, and then tap Reset Wi-Fi, mobile, and Bluetooth.
Confirm the action, then restart your device. This will reset network configurations but not delete personal files.
Disable Call Blocking or Spam Protection.
The OnePlus dialer includes spam filters that may mistakenly block new numbers. Adjusting these settings ensures that legitimate calls are not rejected.
- Open the Phone app, and then tap the three-dot icon.
- Tap Settings, and then tap Caller ID & spam.
Turn off Filter spam calls or Block suspected spam calls, then test by calling your number from another phone.
Update Software.
Outdated software may cause random bugs with call handling. Updating your phone ensures compatibility with carrier networks and fixes known issues.
- Open Settings, and then tap System.
- Tap System update, and then tap Check for update.
Install any available updates, then restart your OnePlus 13.
If new numbers still cannot reach you, try inserting your SIM card into another device to see if the issue follows the SIM or stays with the phone. This helps determine whether the problem is with your carrier or the device itself.
Once fixed, your OnePlus 13 should start receiving all calls normally again.
FAQs
Why can I only receive calls from saved contacts?
Your Do Not Disturb or spam filter may be blocking unsaved numbers. Check the call settings and disable call restrictions.
Can a faulty SIM card cause this issue?
Yes. A damaged or loosely inserted SIM card can prevent incoming calls. Try reinserting or replacing it if the problem continues.
Will resetting network settings delete my files?
No. Resetting network settings only clears saved Wi-Fi, Bluetooth, and carrier configurations without affecting personal data.
