[Hilo] What’s the way to detach GPRS?

Answer: Please find the flowing ways for your reference:
1/ Using <AT+CGATT=0> to de-attach.
2/ Using <AT+CGCLASS= “CC”> for circuit switched mode, it’ll de-attach the GPRS.
3/ Using <AT*PSGAAT =0> for disable GPRS attach at switch on, so no GPRS attach after.
