Another similar, but with a totally different feature set is JINA Drawer.
If it interests you, as my thanks for your help here, I've adopted a lot of Michael Bazzell strategies for privacy. I use a Pixel 8a in my back pocket as a hotspot for my Pixel 8 Pro that has no SIM card. It gets wifi from the 8a unless I'm home. The 8a has location disabled and was purchased under a pseudoname from Amazon using a throwaway account and delivered to a dropbox. I was able to avoid KYC with US Mobile. My VoIP account is with VoIP.ms & I use Groundwire softphone. The cost is carrying around the 2nd phone, along with my text messsages chopped into 160 character SMS segments. But, except for maybe the NSA, I'm not geo-tracked.
I spend $44 for unlimited data with US Mobile + ~$5/month with VoIP.ms. I burnt a few brain cells getting it all working, but I'm a lot more free as a citizen.

The digital book is a downloadable .PDF.
I use simplelogin for anonymous email forwarding with a 3-character .ME custom domain. They have a reverse alias that helps a lot.
BTW, I'm not connected to Bazzell, US Mobile, VOiP.ms, or simplelogin.
