To make it even more difficult you have providers offering a serive from the same provider/platform but having small print in their terms that state things like fair use without giving a clue waht that is, others force you a minimum volume per month, quater others have ration's of inbound outbound calls. Yet other don't update websites to reflect update prices.

To make it easy I would not use a provider who hides costs, minimums or ratio's in their terms. I prefer companies that a clear and don't hide anything for you. There are a few that don't and you could compare those more easily.
