I'm so clueless when it comes to phones, honestly. I don't know how they work these days. I bought a Galaxy S9 a few months ago and only put $30 on it. Somehow, I'm still able to make calls…
Anyway, if I reply to messages/texts in the 'messages' box, does that cost me anything? Or is it more like Messenger these days?
