Critical

Setting	Description
MOSimFallbackVoicemailNumber	Partners who do not have the voicemail numbers on the device SIM can configure the voicemail number for their devices. If the voicemail number is not on the SIM and the registry key is not set, the default voicemail will not be set and the user will need to set the number. Set MOSimFallbackVoicemailNumber to the voicemail number that you want to use for the phone.
SimOverrideVoicemailNumber	Mobile operators can override the voicemail number on the UICC with a different voicemail number that is configured in the registry. Set SimOverrideVoicemailNumber to a string that contains the digits of the voicemail number to use instead of the voicemail number on the UICC.

IgnoreProhibitedDialingPrefix	Ignore prohibited dialing prefix. An OEM/MO can specify a certain set of strings by region that when dialed will block a user's caller ID from being displayed on the device receiving the call. The list is separated by semicolon. This setting does not apply beyond Windows 10, version 1709.
IgnoreUssdExclusions	Set as True to ignore Unstructured Supplementary Service Data (USSD) exclusions.

Set UssdExclusionList to the list of desired exclusions, separated by semicolons. For example, setting the value to 66;330 will override 66 and 330. Leading zeros are specified by using F. For example, to override code 079, set the value to F79. If you set UssdExclusionList, you must set IgnoreUssdExclusions as well. Otherwise, the list will be ignored. See List of USSD codes for values.

If you don't set a value for WiFiCallingOperatorName, the device will always display SIMServiceProviderName Wi-Fi, where SIMServiceProviderName is a string that corresponds to the SPN for the SIM on the device.
