Unable to Send Group Messages

[Sk Tiwari]

I am using an Idea Prepaid SIM on my Lumia 630. Earlier I was using this sim on Samsung Galaxy Grand and I was able to send group messages with ease. But on Lumia 630, I am not able to send messages to a group with just about 5-6 contacts. I have created groups with 6,10,15,20 and 25 contacts. But I am not able to send messages to them. If i create a group of 3 0r 4 contacts I am able to send a group message. Can anybody help.
