The following Knowledge Base article offers up some great steps for troubleshooting cellular call issues on your iOS device:
iPhone: Troubleshooting issues making or receiving calls
Follow the steps below to resolve this issue. Please test after each step.
- Toggle airplane mode: Tap Settings > Enable Airplane Mode, wait five seconds, then turn off airplane mode.
- Check your phone settings:
- Check your Do Not Disturb settings: Tap Settings > Do Not Disturb.
- Check for any blocked phone numbers: Tap Settings > Phone > Blocked.
- See if Call Forwarding is turned on: Tap Settings > Phone > Call Forwarding.
- Ensure that your software is up to date:
- Check for a carrier settings update.
- Check for an iOS software update.
Note: Some updates may require a Wi-Fi connection.
- If the iPhone has a SIM card, reseat the SIM card.
- If the iPhone 4 or iPhone 4s is on the Verizon network, dial *228 from the iPhone and select option 2 to update the Preferred Roaming List (PRL). The PRL determines the cellular towers the phone uses for cellular service, selecting those with the best signal strength.
- Reset the network settings: Tap Settings > General > Reset > Reset Network Settings.
- Try to make or receive calls in another location.
- Attempt to isolate to one network band:
- If you're having the issue on LTE, disable LTE, if possible, and try again.
- If you're having the issue on 3G/4G, disable 3G/4G, if possible, and try again.
- Contact the carrier to check the following:
- Your account is properly configured to use the specific iPhone that has the issue.
- There are no localized service outages.
- Your account doesn't have a billing-related block.
- Your calls don't have errors on the carrier system.
- Restore the phone as new.
If the above steps don't resolve the issue, go to an Apple Retail Store, carrier, Apple Authorized Reseller, or contact AppleCare to send the phone in for service.
Thanks for reaching out to Apple Support Communities.
Cheers,
Pedro.

Nov 5, 2014 7:23 PM in response to Darkerinby Clj810,My husband is having the same problem with his iPhone 5S. He is being bounced back and forth between our carrier and Apple. He didn't have a problem until after he downloaded iOS 8.02. It sounds like a remedy that should come from Apple. And after reading some of the problems on the other Apple support communities, LOTS of users are having a variety of issues. I am so glad that I did not download the update on my phone!

Nov 5, 2014 7:39 PM in response to Clj810by drshame,+1 Same exact problem with my formerly working fine Iphone 5 under the latest Ios "upgrade".
I finally got an AT&T Microcell at home and it's dropping THAT too...even though it shows 5 bars of connectivity.
