I spend $10 a month with Verizon right now for 500 texts a months. I'm looking to get rid of that package but I do a lot of texting. Over the past few years I have seen several free texting apps where they give you a "texting phone number". How do they work? Can these companies in turn read/access/ or even hijack my phone and use it to send texts to other recipients without my knowledge? I've seen a lot of people use these apps but I'm just worried about my security. I don't want a "company" or someone half way across the planet access my phone via the number they gave me to text and send messages to other recipients with that number. Thanks guys.
