Getting slowdowns (throttled) over 5 Gig on "unlimited" plans is certainly plausible and quite likely, as all carriers are very loosely defining "unlimited" as unlimited access, but reserving the right to throttle (way down in many cases) data transfer speeds if a base limit (2 Gig, 5 Gig, whatever the plan stipulates or is implicitly assumed) is exceeded.
The thing is, strictly speaking, there can be NO unlimited data plans in terms of data amounts transferred, since users a billed on a term basis (30 days) so ultimately there is an upper limit to the monthly data consumption, even if the plan is marketed as unlimited. So doing away with unlimited data is really more of an issue of semantics more than anything else, so I wish they would just quit the practice and clearly specify monthly consumption limits in the terms of the plan. That way, we know just how much we are being gouged (poor value for dollar) when we think our rates are too high.
