Not sure about the coverage, as I live in FSD.
PTCL has limited the downloading to 75GB, so if you download a lot, it isn't worth it.
Once you exceed your limit, you will have to live with 256kbp/s until the calendar month ends.
For normal use, in car etc. it is perfect, but mine does reset a lot, like every 5-7 minutes.
TL;DR: if you use more than 75gb, not worth it, for normal office use etc. Yes go for it!
