How can I create multiple virtual phone numbers

I’m looking for a way to create virtual phone numbers to be used for verification purposes.

I do not want to use any phone number rental services, I want to be able to keep the number.

What’s some good ways to do this without paying for millions of data plans?

I would think textfree and textnow would be a good option, Google voice is also another alternative, Number rentals isn't bad considering you can rent a number for around $15 per month. Also pay as you go prepaid plans can be as low as $10 per month.

Aint' no free lunch in this world..
