SMS Messages to multiple contacts at one go.

[AC Question]

I am trying to send SMS messages to multiple contacts at one go from my new Android 5.1.1 Lollipop Micromax AQ4501 phone. However, such an SMS is getting converted to MMS and it simply doesn't go through. When I send this SMS to only one single contact, it readily gets through. Butnthen this task becomes very difficult when I have to send such one single same SMS message to multiple contacts at a time.

How do I achieve this task goal of mine?
