To switch back to Wi-Fi, tap next to the network name, then tap Use Wi-Fi for Internet. See the Apple Support article Use 5G with your iPhone.
Note: If a Wi-Fi connection to the internet isn’t available, apps and services may transfer data over your carrier’s cellular network, which may result in additional fees. Contact your carrier for information about your cellular data rates. To manage cellular data usage, see View or change cellular data settings.
