Unfortunately, I did not own a Blackberry 3 years ago and I personally am not a fan of Howard Stern, NCAA, NHL, etc. I enjoyed it for the absence of commercials. I wish I had owned a smart phone years ago🙂
AT&T had the option to remove the unlimited plans when the phones were upgraded, but they decided to allow users to keep them. If AT&T can't support this usage, they shouldn't sell it.
For the record, my AT&T service is fine. Fast data and clear voice. I do tend to drop call when switching towers, buts that's a more fundamental issue with mixed 2g/3g networks.
I use about 6gb a month...most ever was 56gb on a trip and was just watching movies on Netflix the whole way there and back. Curiously after that I got a text from AT&T about the new data plans, don't think they monitor users??
