Yes.
Your account can be put on a 6 month hold which means you can't add any lines during that time. I have been put on this hold in the past. They wanted 6 months of good pay history. They say there is no way around this. There is, if you know how to communicate, and are persistent.
You should be able to do as many AOLs as you'd like. I don't think that causes problems.
Are you currently having these problems?
Got it, so if they restrict your account for whatever reason, it will only prevent you from adding lines, not AOL them. I'm asking because I'm afraid of being in a situation where I have UDP lines on my account and I can't unload them because my account is restricted. Luckily I don't have any of these problems. With regard to the 6 months payments, I've been a VZ customer for over 5 years and have never been late with payments so guessing that will be a plus for me.
