As a third alternative, you might want to check out Ooma. I purchased the device. (Ooma Telo Free Home Phone Service
https://www.amazon.com/dp/B00I4XMEYA..._P0vwybQA2EPVN) and the basic service is $5 a month. The basic service includes caller ID, voice mail, an app so I can listen to messages on my phone, and a bunch of other things. You plug the device into a regular phone and it works like a landline, with on the go features. I had to have a line for the daycare and found this was the best option.
