·AT&T DSL Service
·Verizon Online DSL
Agreed nothing works better an a POTS line but even large telcos are trying to phase them out for cellular. Also I have GV and a obi 100 and it works beautifully at my IL residence and has so for over a year. The ATT modem, the OBi and 1 corded phone are all on one UPS rated at 750va. so even if power goes out I still have home phone service. My FL residence has CDV for elderly grandparents (safety reasons). However minus 911 my GV line does everything my CDV does and it doesn't cost me a thing per month.
