I've had all texts blocked for years, and you're damn right I'll ignore any text that does get through. Never used them, don't see the point. I don't want pay-per-use, I want blocked 3G/4G data, just like I have blocked text messages. No incoming, no outgoing, no surcharges. Plain and simple.
Thanks for being a dick about it, and completely missing the point of what the customer (me) wants.
Also, please remember that I've never agreed to any changes in the contract. Just because I pay month-to-month now, doesn't give AT&T any legal right to change the terms of the contract. Same as renting a house or apartment. They can't change the terms of your rent without you signing a form to agree to it. I also never agree to any change when I pay my bill, so I'm pretty sure I could fight and win in court to not have a data plan. Not that it would help random other consumers or people changing from one provider to another though, so why bother. The first provider who DOES let me sign up with no data plan, will be the one I switch to.
