View data usage

Note: The amount of data displayed is the amount used since the statistics were last reset. To reset the statistics, scroll to the bottom, then select Reset Statistics. To check your current month's data usage dial *data# (*3282#) on your mobile phone to receive a text message with the current bill cycle's usage.

Enable Low Data Mode
Low Data Mode helps apps on your iPhone reduce their network data use. From the Cellular screen, select Cellular Data Options > Data Mode > Low Data Mode.
Turn Wi-Fi Assist on or off
From the Cellular screen, scroll to the bottom of the page, then select the Wi-Fi Assist switch.
Note: Wi-Fi Assist regularly checks the Wi-Fi connection to determine signal strength. If the Wi-Fi signal strength drops below a specific range, Wi-Fi Assist will automatically switch the session to cellular data until the Wi-Fi signal improves. Wi-Fi Assist is an optional setting that is turned on by default and can be turned off at any time. Data rates apply for cellular connections.
