What does it mean if my network signal is weak?

If your network signal is weak, it means that your device is not receiving a strong enough signal from the nearby cell towers or base stations. This can result in a range of issues, including dropped calls, slow internet speed, and difficulty in connecting to the network. There could be multiple reasons behind a weak signal, including distance from the nearest tower, physical obstructions like buildings or trees, or even network congestion in your area. To improve your signal strength, you can try simple troubleshooting steps like moving to a different location or restarting your device. If the problem persists, contacting your service provider, such as Optus, would be helpful as they can provide further assistance in resolving the issue.
