What is a landline phone service provider?

A landline phone service provider is a company that provides a physical, wired connection to the public switched telephone network (PSTN) through traditional copper wire or fiber optic cables. This connection is used to transmit voice and data signals, allowing people to make phone calls and access the internet. Landline service providers offer various calling plans and features, including caller ID, call waiting, voicemail, and more.

Landline service providers can be regional or national and can vary in terms of pricing and available features. Some examples of landline service providers in the United States include AT&T, Verizon, and Comcast. Other companies, such as Vonage and Ooma, offer internet-based phone service that allows users to make calls over the internet instead of traditional phone lines.
