| 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 |

| 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 |

| AT&T | 7969 Parkland Pl | poor to no signal on AT&T | 2015 |

| Verizon | 11456 Keymar Rd | Spotty coverage, lots of dropped calls.  Emails & text messages are more reliable, but even they may take some time to go through. | 2015 |
