abstract fun onRegistrationFailed(
    cellIdentity: CellIdentity, 
    chosenPlmn: String, 
    domain: Int, 
    causeCode: Int, 
    additionalCauseCode: Int
): Unit

Report that Registration or a Location/Routing/Tracking Area update has failed.

Indicate whenever a registration procedure, including a location, routing, or tracking area update fails. This includes procedures that do not necessarily result in a change of the modem's registration status. If the modem's registration status changes, that is reflected in the onNetworkStateChanged() and subsequent get{Voice/Data}RegistrationState().

Because registration failures are ephemeral, this callback is not sticky. Registrants will not receive the most recent past value when registering. The calling app should have carrier privileges (see TelephonyManager.hasCarrierPrivileges) if it does not have the android.Manifest.permission#READ_PRECISE_PHONE_STATE and android.Manifest.permission#ACCESS_FINE_LOCATION. If the calling app doesn't have android.Manifest.permission#ACCESS_FINE_LOCATION, it will receive CellIdentity without location-sensitive information included.
Requires android.Manifest.permission#READ_PRECISE_PHONE_STATE and android.Manifest.permission#ACCESS_FINE_LOCATION

Parameters
cellIdentity CellIdentity: the CellIdentity, which must include the globally unique identifier for the cell (for example, all components of the CGI or ECGI). This value cannot be null.
chosenPlmn String: a 5 or 6 digit alphanumeric PLMN (MCC|MNC) among those broadcast by the cell that was chosen for the failed registration attempt. This value cannot be null.
domain Int: DOMAIN_CS, DOMAIN_PS or both in case of a combined procedure. Value is android.telephony.NetworkRegistrationInfo#DOMAIN_UNKNOWN, android.telephony.NetworkRegistrationInfo#DOMAIN_CS, android.telephony.NetworkRegistrationInfo#DOMAIN_PS, or android.telephony.NetworkRegistrationInfo#DOMAIN_CS_PS
causeCode Int: the primary failure cause code of the procedure. For GSM/UMTS (MM), values are in TS 24.008 Sec 10.5.95 For GSM/UMTS (GMM), values are in TS 24.008 Sec 10.5.147 For LTE (EMM), cause codes are TS 24.301 Sec 9.9.3.9 For NR (5GMM), cause codes are TS 24.501 Sec 9.11.3.2 Integer.MAX_VALUE if this value is unused.
additionalCauseCode Int: the cause code of any secondary/combined procedure if appropriate. For UMTS, if a combined attach succeeds for PS only, then the GMM cause code shall be included as an additionalCauseCode. For LTE (ESM), cause codes are in TS 24.301 9.9.4.4. Integer.MAX_VALUE if this value is unused.
