Allow more than 10 people on a group SMS

I work for a large real estate team and we recently moved all our numbers over to Ring Central from Mitel. One thing we were not aware of is that we cannot have more than 10 people in a group SMS, which is pretty frustrating. We need to be in communication with anywhere from 11-23 people at any given moment. Not being able to do this causes issues with our business and is forcing us to seek other alternative options. Apple lets you have up to 32 people in a group message. Can this be escalated quickly?
