General :: New Phone For Mass Texting

I'm looking to upgrade my phone. Aside from normal phone use my main goal is to get a phone that will send a text message to a very large group of people all at once. My current phone Samsung Epic 4g Touch will do this but i have to create the message and then from the address box go to the group and one by one touch in each member (almost 200 in the group). I have my groups already but i would like to just add the whole group all at once. I don't care about the responses being in the same thread or anything else, I just want to add the group all at once to the address box.
