| Verizon | 200th Ave | Date service for verizon is bouces between 1x and 3g but per Verizon data maps this is a 4G area - spent some time with Verizon technical support - they indicated after researching the matter that their tower is too far south to give 4G service. They said the farther south I go on this lake the better my data service will be - I got verizon service specifically so I can stream media while anchored on my boat in this area and was some what disappointed. Also I used to work much better at this location a year ago but somehow towers changed. Mean while my friend with US celluar got 4G service and I even did a speed test to achieve about 14 Mips with US Cellular at this location | 2015 |
