You just contradicted yourself
The top plans now have 10GB/mo before the throttling may
be applied (I've been throttled once, and for only two days).
If you're using this for residential, it would make a ton more sense to get 5Mbps DSL or so. It will be consistently fast.
Mobile internet is meant to be used on the go or in areas without wired service.
And since you're in a Wind zone, it's pretty much guaranteed you'll have wired available too
