Sms​Device Sms​Device Sms​Device Class

Definition

Supports the operation of a mobile broadband SMS device.

Note

This functionality is only available to mobile operator apps and Windows Store app given privileged access by mobile network operators, mobile broadband adapter IHV, or OEM. For more information, see Mobile Broadband: device apps.

Note

Note that this class and its methods are supported for the maintenance of legacy desktop apps that used it in earlier versions of Windows; and if you do use this class, you must specify the Windows.Devices.Sms.LegacySmsApiContract in your app's manifest. Do not use this class if you are developing new apps for Windows 10. Instead, use the members of this namespace that do not require the Windows.Devices.Sms.LegacySmsApiContract.

Remarks

Apps that use the Windows.Devices.Sms API to send or receive text messages fail with E_ACCESS_DENIED if the user revokes access.

If access to the SMS device has been given to an app:

  • Calling GetDefaultAsync or FromIdAsync triggers a consent prompt the first time the app is run.
  • The error handlers for the asynchronous methods of GetDefaultAsync and FromIdAsync receive E_ACCESS_DENIED if the user did not grant permission in the consent prompt or if permission is revoked.
  • If the user re-enables access to SMS after revoking it, call GetDefaultAsync or FromIdAsync again to access SMS. For example, the error handler for E_ACCESS_DENIED error could display UI to instruct the user to re-enable SMS using the settings charm and to then tap a button to retry accessing SMS. The code behind the button should call GetDefaultAsync or FromIdAsync before making any other calls.
  • If the app is registering for the SMS background event (Windows.ApplicationModel.Background.SystemTriggerType.SmsReceived ), the app has to first call GetDefaultAsync or FromIdAsync again to access SMS to ensure the app has access. Calling GetDefaultAsync or FromIdAsync from the background task will not trigger a consent prompt. If it is a first time run or if the user did not grant permission or if permission is revoked then it will receive an E_ACCESS_DENIED.

The first use of the SmsDevice object to call FromIdAsync or GetDefaultAsync by applications written in C# or C++ should be on the single-threaded apartment (STA) thread. Calls from a multi-threaded apartment (MTA) thread may result in undefined behavior.

Properties

AccountPhoneNumber AccountPhoneNumber AccountPhoneNumber

Returns the phone number associated with the SMS device. The phone number can be used to associate incoming messages with the account and possibly an external storage mechanism such as an account inbox.

public PlatForm::String AccountPhoneNumber { get; }public string AccountPhoneNumber { get; }Public ReadOnly Property AccountPhoneNumber As string
Value
string string string

A string representation of the account phone number.

MessageStore MessageStore MessageStore

Accesses the on-device message store. The store holds messages until a client can retrieve them. On some devices, for example, the store may correspond to the SIM storage for SMS messages.

Methods

CalculateLength(SmsTextMessage) CalculateLength(SmsTextMessage) CalculateLength(SmsTextMessage)

Estimates the transmitted message length of the specified text message. The estimate can be useful to clients who want to give an indication of how many messages will be sent on the network to carry the text of the full message.

Parameters
message
SmsTextMessage SmsTextMessage SmsTextMessage

A reference to the SMS text message to measure.

Returns

A reference to an SmsEncodedLength structure that is populated with the length information.

Remarks

The SmsReceivedEventDetails interface handles the details of a received message; you can pass the DeviceInformation ID from that interface to this method to activate the device and retrieve additional message details, such as the sender and the body of the message. Because the device might be busy, the operation executes asynchronously. The asynchronous operation object returns immediately.

FromNetworkAccountIdAsync(String) FromNetworkAccountIdAsync(String) FromNetworkAccountIdAsync(String)

Creates an instance of SmsDevice for the specified Mobile Broadband network account ID.

Parameters
networkAccountId
System.String System.String System.String

The Mobile Broadband network account ID to use to select the corresponding mobile broadband device to use for the SMS device

Returns

When this method completes, it returns the SmsDevice for the specified Mobile Broadband network account ID.
