Why Can’t New Numbers Call My vivo X300 Pro?

If new numbers cannot call your vivo X300 Pro, incoming calls from unfamiliar contacts may go straight to voicemail or fail to reach your phone entirely. Calls from saved contacts might still come through, which makes the issue confusing.

In most cases, the problem comes from call blocking settings, Do Not Disturb rules, or spam protection features that filter unknown callers. A few quick checks can usually restore normal calling behavior.

Why New Numbers Cannot Call Your vivo X300 Pro

• Unknown callers may be blocked by your call settings.
• Do Not Disturb may be set to allow calls only from contacts.
• A spam filter or call screening feature may reject unfamiliar numbers.
• Your carrier may be filtering suspected spam calls.
• Third party call blocking apps may be restricting unknown callers.

Check if Unknown Callers Are Blocked

Your phone may automatically block calls from numbers that are not saved in your contacts. This setting is useful for avoiding spam, but it can also prevent legitimate callers from reaching you.

1. Open Settings, and then tap Phone.
2. Tap Blocked numbers, and then check if Block calls from unknown numbers is enabled.
3. Turn the option off, and then ask the caller to try calling again.

Review Do Not Disturb Settings

Do Not Disturb can silence or block calls from numbers that are not in your contact list. If this setting is active, only selected contacts may be allowed to call you.

1. Open Settings, and then tap Sound and vibration.
2. Tap Do Not Disturb, and then check if the feature is enabled.
3. Tap Allowed calls, and then choose Everyone instead of Contacts only.

Check Spam and Call Screening Features

Many phones automatically filter suspected spam calls. Sometimes these filters block legitimate numbers, especially if the caller is new or not recognized.

1. Open the Phone app, and then tap the menu icon.
2. Tap Settings, and then look for Spam protection or Call filtering.
3. Turn the feature off temporarily, and then test if the call comes through.

Check If the Number Is Accidentally Blocked

If the caller was previously blocked, your phone will automatically reject their calls. Removing the number from the blocked list restores normal calling.

1. Open the Phone app, and then tap the menu icon.
2. Tap Settings, and then tap Blocked numbers.
3. Find the number in the list, and then tap Remove or Unblock.

Restart Your Phone

A simple restart refreshes network services and clears temporary calling glitches. It can also restore connections between your phone and your carrier’s network.

1. Press and hold the Power button, and then tap Restart.
2. Wait for the phone to reboot, and then ask someone with a new number to call you.

If new numbers still cannot reach your vivo X300 Pro after trying these steps, the issue may be related to your carrier or SIM configuration. Contacting your network provider can help confirm whether call filtering or account restrictions are affecting incoming calls.
