# Troubleshooting "No Service" Issues on Your IP Phone: Steps to Fix It

## This article explains why your phone may display "no service" after connecting and provides steps to troubleshoot the issue.

 

## What are the possible reasons for 'No Service'?

1. **Network Outage**: There may be an ongoing network outage affecting service in your area. This can happen due to maintenance or technical issues.
2. **Router Issues**: If your phone is connected to a network via Wi-Fi, problems with the router can lead to a loss of service.
3. **Device Configuration**: Incorrect settings on your device can also result in a "no service" message.

## How do I fix 'No Service' on my IP phone?

1. **Check for Network Outages**:
   
     - Confirm if there is a known outage in your area. You may need to contact your service provider for updates.
2. **Reboot Your Router**:
   
     - Unplug the power from your router for at least 5 minutes.
     - Plug the router back in and allow it to fully restart.
     - Once the router is back online, reboot your phone to see if the service is restored.
3. **Verify Device Settings**:
   
     - Ensure that your phone is set to the correct network mode (e.g., LTE, 3G).
     - Check if Airplane Mode is turned off.
     - If settings appear correct but the issue persists, try resetting your network settings: go to your device's Settings menu, locate the Reset or General Management section, and select Reset Network Settings. Note that this will remove saved Wi-Fi passwords and VPN configurations.
     - If your IP phone requires manual provisioning (e.g., entering SIP credentials or a provisioning server address), verify that these details are entered correctly. Contact your service provider if you are unsure of the correct values.
4. **Contact Support**:
   
     - If the issue persists after trying the above steps, reach out to your service provider for further assistance.

## Summary

A 'no service' status on your IP phone may result from network outages, router faults, or incorrect device configuration. The troubleshooting steps above are designed to address the most common causes. If problems continue, contact United Business Solutions technical support for further assistance.
