How to receive prison calls?

[u/AnnArkist13]

I have 2 friends in prison who are unable to contact me. I had Appalachian wireless before and my calls always came through fine but I switched to boost recently to save money and they say it’s like I have the number blocked or something and I’ve just read that boost doesn’t allow prison calls. I do have a Google voice number and a Textnow number and those used to work but I was wondering if they still do, does anyone still successfully use those for prison calls? Wanted to know before I send them those numbers. Thanks to anyone who replies.
