Yeah, 5G works (I’m on it at the moment!). No issues with MMS, but I haven’t tested RCS since I’m on /e/OS (which doesn’t support RCS as far as I’m aware - I just use SMS/MMS and Matrix). The visual voicemail functionality in the stock /e/OS Phone app doesn’t work with Mint Mobile, but the T-Mobile Visual Voicemail app does work.

Yup! I daily drive a Fairphone 6 with Mint Mobile in the US.

Just read The Rust Book. It’s free, and you’re more than well-prepared.

Then when you finish that, get Rust for Rustaceans.

Or if books aren’t your thing, there are some alternative learning methods on the Rust site.

The FLX1 had wireless charging. And a headphone jack. And a replaceable battery… 😔
