+ * Defined in TS 102.223 Section 8.74.
+ *
+ * According to 3GPP TS 24.008, Section 10.5.1.4, IMEISV is composed of
+ * 16 digits and totally 9 bytes are used to represent it.
+ *
+ * Bits 1-3 of first byte represent the type of identity, and they
+ * are 0 1 1 separately for IMEISV. Bit 4 of first byte is the odd/even
+ * indication, and it's 0 to indicate IMEISV has odd number of digits (16).
+ * The rest bytes are coded using BCD coding.
+ *
+ * For example, if the IMEISV is "1234567890123456", then it's coded as
+ * "13 32 54 76 98 10 32 54 F6".
