One of the most common questions I am asked about wireless phones is if data usage is charged toward your wireless account plan while your phone is connected to a personal or public Wi-Fi network.
The answer is no. Generally, when your phone is connected to your home or any other Wi-Fi network, it will not connect to the 5G, 4G, 3G, or any type of wireless carrier network. Any data used via Wi-Fi will not count toward your data plan.
However, there are instances where your phone may switch over to the carrier’s wireless data network without you knowing. Have a look at these settings if they apply to you:
- Android devices have a setting under “Settings” > “Wi-Fi” > “Advanced” > “Keep Wi-Fi on during sleep“. If this setting is set to “Never“, your Android will connect to the wireless carrier network. Ensure it is set to “Always” if you want to remain connected to Wi-Fi even when the phone is sleeping.
- iPhone devices have a setting under “Settings” > “Cellular” > “Wi-Fi Assist” that controls whether the iPhone will use the wireless carrier data networks if the Wi-Fi signal is poor.
- Most phones have an option under “Settings” to turn “Cellular data” completely off. You can turn “Cellular data” off if you want to be completely sure you are not using the wireless carrier’s network.
If you want to be totally sure, your wireless carrier should provide access to data logs via their website. You can check these logs and review your usage to ensure you are not using your precious carrier data.
