I need an app for Android galaxy S5 that can do texting. Need min of 20 numbers in 1 group text

I have messenger, but it only allows 10 contacts per group. Id like 1 group if possible

There are at least a dozen SMS apps out there. Install them and try them. (It's what I'm still doing with SMS and email apps - I haven't found one of either that I really like. Textra is a good SMS app, but I can't live with the UI design. And while I like the checkboxes in the old email app, it's getting a bit long in the tooth, and it's no Thunderbird.)
