iPhone 5s, iOS 12
Were you previously able to make and receive calls on this device? If not, have you contacted your carrier to activate your device?
If you were previously able to make and receive calls on this device, go to settings>cellular>data roaming options. On
'enable lTE, what is selected? Data only or Voice and Data? Try selecting 'Voice and Data'. Next, check for carrier updates. Tap settings>general>about>tap carrier. If a carrier update is available, it will tell you after tapping on the carrier.
Next, go to general>reset>reset network settings. Afterwards, you'll need to reconnect to wifi...no data is lost when resetting the network settings. If you're still unable to make or receive calls, remove your SIM card and reinsert it. If, after these troubleshooting steps, you are still unable to make or receive calls, please contact your carrier.
**Also, at the top left corner of your screen, do you see your carrier listed or does it say 'no sim' or 'sim invalid'? Do you have carrier signal bars in the upper right hand corner of your screen? Also, in order to be able to accurately walk you through the correct troubleshooting steps for an issue, it is important to post as much relevant info as possible.
