        const string toNumber = "recipient_phone_number";

        // Message content with emoji
        const string messageBody = "Thank you for using Our Product 🏍️ ✨ Be Happy Be Safe!";

        var message = MessageResource.Create(
            body: messageBody,
            from: new Twilio.Types.PhoneNumber(fromNumber),
            to: new Twilio.Types.PhoneNumber(toNumber)
