This setting is only supported on Windows 8.1 and versions of Windows 10 before Windows 10, version 1703.

Windows 10, version 1703
AutoConnectOrder Windows tries connections to the APNs provided by the operator and marked as "auto-connect" in the COSA database until it successfully connects to the mobile network. If all auto-connect attempts fail, Windows will show a prompt allowing the user to pick an APN or enter a custom APN. Optional If you have more than one access string for an operator, this setting must start with 1. This is needed for Windows to try several APN entries that share either an IMSI range, ICCID range, CDMA provider ID, or CDMA provider name when the user tries to connect. Windows 10, version 1809
SupportDataMarketplace A true/false string describing whether a profile entry supports Mobile Plans. Optional

Before enabling this setting, please ensure that your mobile operator is part of the Mobile Plans program.

If left blank, defaults to "false."

Windows 10, version 1703
SPN An identifier string for the Service Provider Name (SPN) Optional Helps to identify the MO/MVNO's network. If left blank, defaults to empty string and does nothing. Windows 10, version 1703
AlwaysOn Describes whether the connection is always on or not. Required If left blank, defaults to "true." Windows 10, version 1703
PurposeGroups A string specifying the purposes of the connection by a comma-separated list of GUIDs representing purpose values. Required The following purpose values are available:

If left blank, defaults to "Internet."

Windows 10, version 1703
PurposeGroups A string specifying the purposes of the connection by a comma-separated list of GUIDs representing purpose values. Optional The following optional purpose groups value is available:
  • LTE attach
Specifying an LTE attach APN through COSA is typically unnecessary because the attach info is usually managed directly by the underlying modem's hardware. However, in the case where the modem's hardware does not have an LTE attach APN value and the network is incapable of assigning one to the UE, the MO can optionally provide LTE attach information so that the UE can LTE attach without the user manually entering a value.
Windows 10, version 1903
IPType A string specifying the network protocol of the connection. Optional Possible values:
  • IPv4
  • IPv6
  • IPv4v6

If left blank, defaults to "IPv4."

  • 16 x 16: 8-bit 256 color
  • 16 x 16: 4-bit 16 color
Windows 10, version 1709

If left blank, defaults to 1.

Windows 10, version 1709
UIName If the target condition values (SPN, MCC, MNC, IMSI Range, ICCID Range, etc.) can't indicate the unique entry, then COSA will display this name to the end user to enable manual selection of which MO's connection value to use. Optional For example, ContosoMVNO is an MVNO. It doesn't have any unique values that can be used to distinguish itself from the main MO network, Contoso. In this case, UIName can be used and will be shown in the Windows Settings UI, enabling the user to manually select which MO provisioning settings to use. Windows 10, version 1709
UIOrder The index to control the UIName value's dropdown list picker position. Required if UIName is specified; Optional otherwise If not specified, defaults to 0. Windows 10, version 1709
ESIM_PROV A true/false string describing whether the profile is to be considered as an eSIM provisioning profile. Important Optional unless the MO supports an eSIM provisioning profile, in which case it is required.

If left blank, defaults to "false."

An eSIM provisioning profile is a single-purpose profile. When it is installed on the eUICC, it enables the user's equipment to establish a limited connection to the MO's walled garden in order to purchase a regular, operational eSIM profile.

Windows 10, version 1709
AppID A string describing the Package Family Name (PFN) and application ID of a mobile operator's UWP companion app. Optional In Windows 10, version 1803 and later, AppID is used to identify MOs with their companion apps. AppID must be declared in this format:

PFN!AppId

Note This format is case sensitive.

To obtain the PFN and AppId for your app, follow these steps:

  1. Acquire the PFN as specified on View App Identity Details.
  2. Locate the AppId by opening your solution's AppManifest.XML file and querying the AppXManifest for the application ID.

For more info about UWP companion apps for MOs, see UWP mobile broadband apps.

Windows 10, version 1803
Hotspot Determines if you want to permit users to share their mobile broadband connection as a personal hotspot. Optional Possible values:
  • Never
  • Always
  • EntitlementCheckRequired

If left blank, defaults to "Always."

The EntitlementCheckRequired option enables users to share their hotspots with an entitlement check, which requires a handler for Windows notification events. If this option is selected, you need to develop an MO UWP companion app to handle the entitlement check requests.

For more info about UWP companion apps for MOs, see UWP mobile broadband apps.

For more info about the EntitlementCheck API, see its UWP API reference page.

Windows 10, version 1803
EnableAutoSlotSwitch Determines if you want to automatically switch slots when a SIM is inserted. Optional Possible values:
  • "false": When a new SIM is either inserted or removed, a toast is displayed asking if the user wants to switch slots. The slot is switched only if the user clicks "yes" on this toast.
  • "true": On SIM insert, the slot is switched automatically and then a toast is displayed informing the user that the slot has been switched. This toast doesn't take any button input from the user. The SIM removed behavior remains unchanged.

If not specified, defaults to "false".

Windows 11
WifiProfiles Wifi profiles that will be included in the system while this mobile broadband profile is active. Optional

This entry supports multiple WifiProfile entries. Each WifiProfile entry must point to an .xml file with a WLANProfile. See WLANProfile Element.

See an example of WLAN Profile using EAP-AKA authentication.
