Sir,
I am trying to use MQTT through EC20 module(Quectel EC20F Revision: EC20CEFAGR06A15M4G).
I use Jio 4G sim.

AT+CGDCONT=1,“IP”,“jionet”
OK
AT+CGACT=1,1
CME ERROR: 100

Hi ,

In Jio SIM context one may be already occupied .

Can you first check AT+CGDCONT?

AT+CGACT?

If context 1 is active better you do use context 2 for PDP activation .

Thank you
Ratan
