9 Commands for Data Services
This chapter describes the AT commands that set and operate data services.
9.1 AT+CGACT - Command for Activating or Deactivating
the PDP Context
After AT+CGACT (command for activating or deactivating the PDP context) is

perform GPRS attachment before attempting to activate the specified PDP context. If
<cid> is not specified, all PDP contexts are activated or deactivated.
