Parameter Type Description

<snt> Number It indicates the requested serial number type. Depending on <snt> value, the

<param_val> parameter in the information text response provides different

information:

• 0 (default value): MT serial number, typically the International Mobile station

Equipment Identity (IMEI)

• 1: International Mobile station Equipment Identity (IMEI)

• 2: International Mobile station Equipment Identity and Software Version Number

(IMEISV)

• 3: Software Version Number (SVN)

• 255: IMEI (not including the spare digit), the check digit and the SVN

<sn> Number MT serial number, typically the International Mobile station Equipment Identity (IMEI)

<imei> String International Mobile station Equipment Identity (IMEI). IMEI is composed of Type

Allocation Code (TAC) (8 digits), Serial Number (SNR) (6 digits) and the Check Digit

(CD) (1 digit).

<imeisv> String International Mobile station Equipment Identity and Software Version Number

(IMEISV). The 16 digits of IMEISV are composed of Type Allocation Code (TAC) (8

digits), Serial Number (SNR) (6 digits) and the software version (SVN) (2 digits).

<svn> String Software Version Number (SVN) which is a part of IMEISV.

<imei_full Number International Mobile station Equipment Identity (IMEI), Check Digit and Software

Version Number.

<param_val> Number/

String

Type and supported content depend on related <snt> (details are given above)
