I had a number of family members in jail that were sent to facilities around the US. I had looked into Pigeonly because of their telephone service rates. Calling inmates is ridiculous - either on their books or calling collect - it's a ransom to call long-distance. What I ended up doing instead was signing up for 3 different google voice numbers in the area codes of the prisons my family were all in and had them call me at the local numbers. While still a lot more than a traditional call, it was astronomically cheaper than long-distance, and cheaper than the plans offered by Pigeonly.
The federal prisons system has email access, and was the cheapest way for all of us to stay in touch. Snail-mail was bad. Sorting and scanning at the prisons is kind of a crap shoot. Sometimes letters wouldn't arrive until 4-6 weeks after we'd sent them. Sometimes they'd show up in 3 days. I think a few showed up 3-4 months latter. The intake office rejects all kinds of letters for arbitrary reasons. They sent back a picture we included with a letter, that my 3 year old had drawn for her uncle. Their note said it was returned because it was an "unsigned card".
My mom's prison had access to video chat. $20 for 15 minutes I think. We tried it 2 times. The latency and lag was really bad. Kind of felt like I was video chatting on an old 320x240 from the early 00s. The apps didn't have any kind of noise canceling / mute function with the mic so unless we chatted on headphones you start an infinite feedback loop. I tried once on computer and once on an iPhone. Because we were only doing it some my mom could see her grandkid, and this 3 year old wasn't into headphones we gave up the video chatting too.
Good on him for helping out people not savvy enough to setup VOIP lines in local area codes and making letter writing easier. Keeping up with people in prison is hard and expensive.
