So, purchase SMS credits to send a limited number of SMS using a webservice. There are free ones that are not so reliable. There are lots of webservices and you should be able to find one by searching the web. Sending SMS via webservices, although not for real-time services, is a very cost-effective solution. SMSEngine.Close() Sending SMS via a webservice SMSPort.WriteLine( " AT+CMGS=" + CellNumber + " r") MyMessage = SMSMessage.Substring( 0, 160) If (SerialIn.Contains( " +CMGS:") = true) Public bool SendSMS( string CellNumber, string SMSMessage) SMSPort.Handshake = Handshake.RequestToSend Public event DataReceivedEventHandler DataReceived Public delegate void DataReceivedEventHandler( string Message) Public event SendingEventHandler Sending Public delegate void SendingEventHandler( bool Done) In a Windows application, follow the steps below: While creating the instance of the class, provide the port to which the modem is connected. The above class exposes three functions: Open, SendSMS and Close. IsOpen = False End If End Get End Property Public Sub Open() _Continue = True RaiseEvent Sending( True)Įnd If End While RaiseEvent DataReceived(SerialIn)Įnd If End While End Sub Public ReadOnly Property IsOpen() As Boolean Get If SMSPort.IsOpen = True Then _ContSMS = True End If If SerialIn.Contains( " +CMGS:") = True Then SMSPort.Read(RXBuffer, 0, SMSPort.ReadBufferSize) SMSPort.IsOpen = True) Then While SMSPort.BytesToRead 0 ReadThread = New Thread( AddressOf ReadPort)Įnd Sub Public Function SendSMS( ByVal CellNumber As String,īyVal SMSMessage As String) As Boolean Dim MyMessage As String = Nothing ' Check if Message Length 0) And ( Public Sub New( ByRef COMMPORT As String) Public Event DataReceived( ByVal Message As String) Shared _Continue As Boolean = False Shared _ContSMS As Boolean = False Private _Wait As Boolean = False Shared _ReadPort As Boolean = False Public Event Sending( ByVal Done As Boolean) Imports System.IO.PortsPublic Class SMSCOMMS If you are using VB.NET for coding the application, you can use the class shared by Jeanred. Copy and paste the code given below into the class.Add a new class file with the name SMSCOMMS.Create a new Windows application or Web Application.The connection settings explained are common for most GSM modems. Sample connection details of the Maestro 20/100 modem can be found here. Connect the modem to the computer according to the setup guide specified in the manual provided with the GSM modem.Understand the AT Command set required to communicate with the modem.First, find the best GSM modem that suits the needs.In contrast, sending SMS via GSM modem has a few additional steps to take care of. Sending SMS via a webservice or endpoints is simplest. Service provider demands a commitment of at least 100,000 SMS per month. Better when the number of SMS exceeds a few 100s per minute.Using endpoints given by service the provider:.Better when it is an online application and a very few number of SMS go every minute, usually few 10s.Better when one wants to implement offline applications and a very small number of SMS go every minute, usually few 10s.What are the ways in which one can send SMS? Let's find out ways to send SMS using C#/VB.NET. The simplest one is to validate a mobile number, and some of the complicated ones could involve sending an SMS after a huge workflow is complete or gone wrong. We can see all the query parameters in the URI.When do you want to send SMS via applications? There could be plethora of use cases for this. Once we enter our credentials, the application will navigate us to a 2-Step Verification page: Now if we try to visit the Companies page without logging in, we are going to end up on the Login screen. Finally, if the verification is valid, we create a new token and send it to the client. If that’s not true, we return a bad request. If previous checks pass, we use the VerifyTwoFactorTokenAsync method to verify if the token is valid for our user and the provider. Again, if we can’t find one, we return a bad request. After that, we try to fetch the user by the provided email. If it isn’t we just return a bad request. Return Unauthorized(new AuthResponseDto ) Īs you can see, we accept the twoFactorDto object from the client and inspect if the model is valid. If (!await _userManager.IsEmailConfirmedAsync(user)) Public async Task Login( UserForAuthenticationDto userForAuthentication) To start with the 2-step verification process, we have to modify our Login action: Generating OTP for the 2-Step Verification Process But if you want to do it in a code, you can use the _userManager.SetTwoFactorEnabledAsync method in the RegisterUser action. The EmailConfirmed column was already set to true and we manually modified the value of the TwoFactorEnabled column.
