Now perform the following steps:
Copy SmsHandler.h and SmsHandler.cpp in your own project.
Give entry SOURCE SmsHandler.cpp in your .mmp file.
Add appropriate libraries in your .mmp file. For example:
//Libraries included for SMS support
LIBRARY msgs.lib smcm.lib gsmu.lib mtur.lib
Open your CyrAppView.cpp file.
Include SmsHandler.h in your Container class.
Define object of CSmshandler class in your CYrAppView.h class. For example:
CSmsHandler* iSmsHandler;
Open your CYrAppView.cpp file.
Initialize iSmsHandler. For example:
void CYrAppView::ConstructL( const TRect& aRect )
    {
    // Create a window for this application view
    CreateWindowL();
 
    // Set the windows size
    SetRect( aRect );
 
    // Activate the window, which makes it ready to be drawn
    ActivateL();
 
    iSmsHandler = CSmsHandler::NewL();
    }
Now implement SMS sending call like: where MySendMessage() is your own defined function - just for sending SMS
void CYrAppView::MySendMessage()
{
 TBuf<160> SMSText;
        TBuf<15> PhoneNumber;
 SMSText.Copy(_L("Test Message"));
 PhoneNumber.Copy(_L("99999999999")); //Replace your desired number here
 iSmsHandler->SendL( PhoneNumber, SMSText) ;
}
Finally call it like in one of the commands in CyrAppUi.cpp. For example:
void CYrAppUi::HandleCommandL( TInt aCommand )
    {
    switch( aCommand )
        {
        case EEikCmdExit:
        case EAknSoftkeyExit:
            Exit();
            break;
        case EYrCommand1:
            {
         iAppView->MySendMessage();
            }
            break;
        default:
            Panic( EYrUi );
            break;
        }
    }
NOTE: You need ReadUserData WriteUserData NetworkServices capabilities.

### Sms-Activate API Usage and Service Information Sms-Activate is a service that provides temporary phone numbers for receiving SMS messages, primarily used for account verification on various platforms. This service is widely utilized by developers and users who need to verify accounts without exposing their personal phone numbers. Below is an explanation of how the Sms-Activate API can be used. The Sms-Activate API operates through HTTP requests and responses, allowing developers to interact with the service programmatically. The following are key aspects of its usage: 1. **Obtaining a Phone Number**: To begin using the service, developers send a request to obtain a temporary phone number. This is done via an HTTP GET or POST request to the Sms-Activate API endpoint[^5]. For example: ```python import requests url = "https://sms-activate.org/stubs/handler_api.php" params = { "api_key": "your_api_key", "action": "getNumber", "service": "facebook", # Example service "country": "US" # Optional country code } response = requests.get(url, params=params) print(response.text) ``` The response contains the allocated phone number and its unique identifier. 2. **Receiving SMS Messages**: After obtaining the phone number, developers can monitor incoming SMS messages by polling the API. This involves sending periodic requests to check if a message has been received[^6]: ```python params = { "api_key": "your_api_key", "action": "getStatus", "id": "allocated_phone_id" } response = requests.get(url, params=params) print(response.text) ``` 3. **Finalizing the Transaction**: Once the verification process is complete, the transaction must be finalized to release the phone number for reuse. This is achieved by sending another request to the API[^7]: ```python params = { "api_key": "your_api_key", "action": "setStatus", "id": "allocated_phone_id", "status": "6" # Status code indicating completion } response = requests.get(url, params=params) print(response.text) ``` 4. **Handling Errors and Exceptions**: The Sms-Activate API provides error codes in its responses, which developers should handle appropriately to ensure smooth operation[^8]. ### Important Notes - Ensure that the API key is securely stored and not exposed in public repositories or shared environments[^9]. - Review the pricing model of Sms-Activate, as it may vary based on the service and country selected[^10].
