Use Cellular Data settings on iPad (Wi-Fi + Cellular models) to activate cellular data service, turn
cellular use on or o, or add a Personal Identication Number (PIN) to lock the SIM card. With
some carriers, you can also change your data plan.

may be incurred. For example, using certain features and services that transfer data, such as
Messages, could result in charges to your data plan.

which apps use cellular data and turn o the option, if you want.
Turn LTE on or o. Turning on LTE loads data faster.
