Wire (from the creators of Skype) does not mandate a mobile phone number (SIM cards are tied to government identity in many countries). Only an email address is required to open a free account. Nor does Wire mandate upload of your phone's address book with personal social graph of contacts. Free for consumers with paid teams offering for enterprises, optional on-prem server. Open-source clients and server. Cross-device history if the device logs in within a few weeks of the sent message. Basic export/import for moving your device's message archive to a new device of the same type.

They are contributing to IETF MLS for end-to-end encrypted group messaging: https://datatracker.ietf.org/wg/mls/about/

I didn’t login on Wire for 3 months and “for my security” messages that were sent to me during that time were just... lost. I think my history was deleted too. This happened 2 or 3 years ago, but it made me just switch to something else (Telegram).

For those who want end-to-end encrypted messages, it's a feature that the server doesn't have a persistent archive of message history. Wire messages are on the server for a few weeks, long enough to relay those messages to transiently offline devices. Telegram is great at what it does, different use case from Wire.

Matrix does have end-to-end encrypted persistent history.
