I know that most providers don't like calls, no less first time calls, from cell phones. Easy LE snag. Some people don't accept calls from "blocked" phones. The phone I call from has a block on it. No, it can't be removed the conventional ways. It's the building I'm in.I tried calling a provider on my cell phone(with a brief explanation), but she hung up on me.Is there something else I can use/do?I would like to try this provider because of her good reviews.Iggy_d
