Function Documentation

int telephony_modem_get_imei ( telephony_h  handle,
char **  imei 
)

Gets the IMEI (International Mobile Station Equipment Identity) of a mobile phone.

Warning:
This is not for use by third-party applications.

The IMEI number is used by a GSM network to identify valid devices and therefore can be used for stopping a stolen phone from accessing that network.

Since :
2.3
Privilege Level:
partner
Privilege:
http://tizen.org/privilege/securesysteminfo
Remarks:
You must release imei using free() on success case.
Since 5.5, this function requires partner level privilege.
Before 5.5, this function required the http://tizen.org/privilege/telephony privilege. Since 5.5, it requires the http://tizen.org/privilege/securesysteminfo privilege.
To avoid unexpected behavior of old version applications which have the http://tizen.org/privilege/telephony privilege, there is an exception in handling the 'permission denied' error.
For an application with api-version 5.5 or higher, if the application doesn't have http://tizen.org/privilege/securesysteminfo privilege, this function returns TELEPHONY_ERROR_PERMISSION_DENIED.
For an application with api-version lower than 5.5, if the application has http://tizen.org/privilege/telephony privilege, this function returns a pseudo value with TELEPHONY_ERROR_NONE instead of TELEPHONY_ERROR_PERMISSION_DENIED. The returned value is not reliable data, it can't confirm the device's identification.
Parameters:
[in]handleThe handle from telephony_init()
[out]imeiThe International Mobile Station Equipment Identity
Returns:
0 on success, otherwise a negative error value
Return values:
TELEPHONY_ERROR_NONESuccessful
