How can we send a sms to the contact number if any changes occurs in some specified fields?

Hi Tanu ,

Yes , you can send sms to the contact number by writing a Trigger on contact updation with the help of various apps (like  Messaging made easy, send notifications or messages – voice, text, email – IoT ; CallHub – Automated SMS and Voice Messages ; etc) in appexchange (some are free and some are paid apps) the sms function calls.

Hope this helps you.

Thanks
