Have my contacts names but no numbers greyed out

Hi buzzer69,

Thanks for clarifying that further. It sounds like your contacts may be saved to your Hotmail account. Did you recently remove a Hotmail account from your device? If so, adding the account back may bring back your contacts. Here are instructions for doing that:

Add an email account to your iPhone, iPad, or iPod touch - Apple Support

Cheers!

Hi buzzer69,

Thank you for using the Apple Support Communities! If you're unable to make phone calls the steps from the article below may help:

If you can't make or receive calls on your iPhone

Update your software

1. Check for a carrier settings update.

2. Check for an iOS software update. Some updates might require a Wi-Fi connection.

Check your settings

If you can't make or receive calls on your iPhone, follow these steps, testing after each step.

Check your network setings

1. Reset your network settings. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This will erase all current saved settings, including Wi-Fi passwords, preferred networks, and VPN settings.

2. Try to make or receive calls in another location.

Check your iPhone settings

1. Turn Airplane Mode on and off. Go to Settings and turn on Airplane Mode, wait five seconds, then turn it off.

2. Check Do Not Disturb. Go to Settings > Focus > Do Not Disturb and make sure it's off. Learn how to use Focus on your iPhone or iPad.

3. Check for any blocked phone numbers. Go to Settings > Phone > Blocked Contacts.

4. Check Call Forwarding. Go to Settings > Phone > Call Forwarding and make sure it's off.

5. Check Silence Unknown Callers. Go to Settings > Phone > Silence Unknown Callers. If the setting is on, a caller must be listed in your Contacts or Recents. Or they must have shared their number in Mail or sent you a message using that number in order for their call to go through. Add their number to Contacts to ensure the phone rings. Calls from some third-party apps might not go through.

Hope this helps!

Have a great day.
