Poor coverage in Southern Wisconsin,  West of Paddock Lake

    Recently joined Tmobile and live in the Chicago area  so far, so good. Went to Lake Geneva over the weekend. Drove 94 to 50 and went West. Once we got past Paddock Lake, either no service or 1 or 2 bars of call only. We were at a hotel on 50 and 12 in Lake Geneva and got no service and no wifi calling inside the hotel. Outside got weak LTE  and went to a restaurant a few miles North got 1 or 2 bars of edge. This is for both phones,  s8 active and iPhone 8. What gives? These are populated areas and well traveled. I would not consider them rural. Does band 12 work there? Will these areas be improved?
