	“SR”: Status Report message storage in NV.
	<mem2>: Memory used to write and send messages.
	“MO”: Mobile Originated SMS message storage.
	In response to a properly entered +CPMS command, the following message indication is
	sent:

	<used1> is the number of used locations for the select area “MT”, “BC”, or “SR” and
	<used2> is the number of used locations for the “MO” area. <total> is the total number of
