Limit on number of contacts I can text

I have a Galaxy S22 and have to send a lot of messages at times. I have each Group limited to 20 contacts but have 24 plus groups. After the 13th group, i can not respond to any contact or send a new text out. I have tried the resetting of network, pulled the SIM card out and even reset the phone itself. Nothing seems to work until about 24 hours later.
