Cellular Data costs

I am at an inflection point with my product development and need to decide whether to stick with the electric imp platform going forward or switch to a competing integrated LTE modem solution. One major data point I need is cost per MB of data for the cellular service. My product has a need to upload a lot more data than a typical IoT product and data costs are one of the major considerations for me at this point. I cannot find any documentation on the data costs for the IMPC001 cellular service. Can anyone tell me at least what range data costs for the cellular service?

@JaronA can help you with this, I’ll ping him a link to this thread.
