The $99 unlimited calling plans might be great for some of us who yak-a-lot or even small businesses, but the Telecom Expense Management Association (TEMIA) thinks that these new unlimited flat-rate cellular plans are a bad idea for large corporations because a “well managed corporate pool plan of voice minutes would average between $50 and $70 per user, whereas these unlimited flat-rate plans are being offered at a fixed rate of $99.”
