Any physical damage to the phone might work as a hindrance for the antenna to transmit and receive radio frequencies. Even incorrect network configuration can also be the cause of the error. Though in most cases the cell phone comes with pre-configured settings and with a slight adjustment, it becomes impossible to complete calls.

In case of incorrect configuration, you have to go to the phone settings followed by Network & Internet option. Lastly, click the Reset option in order to Restore the Default Settings.

3. Limited Resources

The availability of limited resources is another cause of this error. This resource is mainly invested by the phone network provider where most customers inhabit. At the end of the day, they are here to make business and profit. And, they are here to maintain infrastructure. 

If you observe that your area has fewer subscribers, it might be possible that the service provider has not allotted the required source. Thus, you are receiving the error.

6. Service Outage

Most phone network providers assure their customers of 100% uninterrupted service. But, interruptions are inevitable and can take place at any time. The reasons can be due to bad weather, damaged infrastructure, old or damaged circuits and natural disasters that can create service outages.
