Can I still buy an analog phone?

No a digital only phone will not work with analog service, but there are analog/digital phones, I don't know if these are still offered but they were very popular because during the transition from analog to digital, digital coverage was not as good as analog so when you had no digital service it would switch to analog. so the only way to have analog service is if the phone is dual analog/digital or if you have a old analog only phone. you can always look up your phone to see if analog is supported.
