Parameter description
<cid>: numeric parameter, which indicates the index value of the PDP context; value
range: 1–3. For a TE-MT interface, this parameter is local and can be used for other
commands related to the PDP context.
<precedence>: numeric parameter, which specifies the priority level.
<delay>: numeric parameter, which indicates the delay level; value range: 0–4; this
parameter defines the delay of SDU transmission on the GPRS network.
0 (default value): network customization parameter
When the size of SDU is 128 octets:

AT+CGQMIN=?
Queries the supported QoS parameter range.
In case of successful execution:
[<CR><LF>+CGQMIN: <PDP_type>,(list of
supported<precedengce>s),(list of supported <delay>s),(list of
supported <reliability>s),(list of supported <peak>s),(list of supported
<mean>s)<CR><LF>

In case of an error during command execution:
<CR><LF>ERROR<CR><LF>
In case of an error related to the MT during command execution:
<CR><LF>+CME ERROR: <err><CR><LF>
0 (default value): network customization parameter
1: higher than priority levels 2 and 3; implements service commitments with high
priority.
2: higher than priority level 3; implements service commitments with medium
priority.
3: implements service commitments with low priority.
