Stop Treating Phone Numbers As A Digital ID
(notthesolution.substack.com)
This is a most excellent place for technology news and articles.
I've been considering getting a pager or a burner phone just for this
Most phones are dual Sim these days
Better to not associate this number to your main phone anyway. Less likelyhood to have the info stolen from you.
Just get a virtual DID number from something like Voip.ms or virtualphone. There may be other providers out there that use crypto for payment for added privacy, but if all you want to do is be able to keep your real phone # off the grid, these work.
usually they check for VOIP numbers and give you an error. Has to be legit.
