I live in a virtual dead zone. 1 bar of coverage and use Satellite for my high speed internet. We worked with T-Mobile to get better coverage. Ended up with a cell spot (which FYI plugs directly into your modem.) I have a high speed data cap through my satellite provider. We were in internet bliss for 3-4 days, worked great until everything ground to a screeching halt. NO internet whatsoever through our phone data..what happened? WELL I will tell you what happened. The cell spot used our high speed data supplied by our internet company until it was completely maxed. After that- the cellspot was useless.
Even after telling the rep about our situation- the data cap, Satellite and the works, the cell spot was recommended. Well people- it USES your data despite what t-mobile will tell you. PLEASE stop telling people it does not consume data supplied by your other device. If something hooks into your modem- it is USING it.
