| Verizon | I-70 | No 4G service or voice | 2019 | 
| T-Mobile | MD-77 | Catoctin park is generally a dead zone, except on hillside facing Thurmont. Would like to get an AT&T or T-Mobile cell tower somewhere on the high hills here. Would like to have the campgrounds and waterfalls covered. | 2019 | 
| Verizon | 7847 Jackson Mountain Dr | No 4G signal, very limited 3G signal, very limited cellular signal. Many calls to Verizon have only yielded them telling me to purchase a network extender for $250, and they are still unsure if that will work. Different explanations from Verizon - advised this is a extended service area and a no service area. They are still happy to take my money though! | 2014 | 
| AT&T | 7969 Parkland Pl | poor to no signal on AT&T | 2015 | 
| Sprint | US-40 | No service. NOTHING on most of I-68 from Hancock,MD to Cumberland, MD. Or between Cumberland and Morgantown, WV. | 2015 |
