values for context number <cid> to become undefined.

AT+CGDCONT?

Read command returns the current settings for each defined context in the
format:
+CGDCONT: <cid>,<PDP_type>,<APN>,<PDP_addr>,<d_comp>,
<h_comp>[,<pd1>[,…[,pdN]]][<CR><LF>+CGDCONT: <cid>,
<PDP_type>,<APN>,<PDP_addr>,<d_comp>,<h_comp>
[,<pd1>[,…[,pdN]]][…]]

AT+CGDCONT=?

Test command returns values supported as a compound value

Example

AT+CGDCONT=1,”IP”,”APN”,”10.10.10.10”,0,0

OK
AT+CGDCONT?
+CGDCONT: 1,”IP”,“APN”,”10.10.10.10”,0,0

OK
