@ohos.telephony.data (Cellular Data)

The data module provides basic mobile data management functions. You can obtain and set the default slot of the SIM card used for mobile data, and obtain the uplink and downlink connection status of cellular data services and connection status of the packet switched (PS) domain. Besides, you can check whether cellular data services and data roaming are enabled.

NOTE

The initial APIs of this module are supported since API version 7. Newly added APIs will be marked with a superscript to indicate their earliest API version.
