Session

Private messenger that needs no phone number; messages route through a decentralized network.

Free Enough

This app has paid upgrades — but its free tier is the complete product. Most people who use it never feel the need to pay.

Session Pro (from $2.99 USD/month, bought as an in-app purchase through the mobile stores) adds longer messages, unlimited pins and animated display pictures, but free encrypted messaging, groups up to 100 members and attachments up to 10 MB are complete without it.
