The advantage of using MSG91 over Twilio is that our codes do not require any prerequisites. There is no package installation required, without installation you can begin sending SMS. Twilio generates a response with all the details of which the user has prior knowledge. MSG91 generates a Request ID which marks the successful hit of the message. All other details can be fetched anytime under the delivery report section.
