Command syntax: AT+CMSS=<index>[,<da> [,<toda>] ]
Response syntax: +CMSS: <mr> or +CMS ERROR: <err> if sending fails
If a new recipient address <da> is given, it will be used instead of the one stored with the message.
This command selects values for <vp>, <pid>, and <dcs>.

In text mode <vp> is only coded in “relative” format. The default value is 167 (24 hours). This
means that one byte can describe different values:

held in the SC that has the same <mr> and <da> as the previously submitted SM
from the same <oa>.
Message Type Indicator
b1=0 & b0=0 -> SMS-DELIVER (in the direction SC to MS)
b1=0 & b0=1 -> SMS-SUBMIT (in the direction MS to SC)
b4=0 & b3=0 -> <vp> field is not present
b4=1 & b3=0 -> <vp> field is present in relative format
Others formats (absolute & enhanced) are not supported.
