Hi Tish,
I'm inclined to agree with Gwalk. The speeds are going to vary, then add in the extra latency due to travel time with communication between the satellite and your dish. Plus I'm not sure but there's probably going to be a considerable amount of data usage as well. I hope this helps to clarify. Maybe try inquiring through the service reps of blink to see if they've had success in the past with satellite ISP's.
Thank you,
Chris
