EM12 reset PDP contexts

I need to attach multipe PDP contexts for mutli beaerer support. After a factory reset, the context should be reset to defaults, e.g. an empty default bearer, one for ims and one for sos.

I tried the reset command AT+CFUN=1,1, but the added PDP context are still there.
Is there a dedicated command to reset the contexts?

As far as I know, there is no AT command to reset the PDP context, we usually use the AT+CGDCONT command to configure PDP Contexts, so you can manually modify it to become the original setting.

To clear context 7 for example, just use the command AT+CGDCONT=7
