Dead phones caused some concern for people in Luzerne, Schuylkill and Clinton Counties overnight.
Frontier Communications was able to restore service early Thursday morning.
The company says a fiber optic line was cut a line around 7 p.m. on Wednesday.
Many homes and businesses lost landline and wireless service, leaving them without a way to call for help in an emergency.
Frontier worked through the night to get the phones working again in Luzerne, Schuylkill and Clinton Counties.
