Phone service for new property manager

[Alex Polyanskiy]

What phone service do you recommend for a brand new real estate investor. I need a phone number for managing tenants. Some books recommend google voice. Some recommend evoice. I would prefer it to be as cheap as possible as I only have one property, but plan to get more.

This question has been asked in the past, but since then prices have changed and new services have been made.

What have you used?
