It works well enough to use as a daily driver on Bookworm and Trixie (and some other distros) but would only recommend if you're ok with Linux, and either are a developer or don't mind some rough parts around the edges.

E.g. some carriers uses 2 APNs, one for internet and one for MMS. You can send/receive on both, but the router is not yet complete, so if you send/receive media or use a group chat via text, need to switch to MMS mode in settings to do so first, then switch back to internet. Not an issue on most carriers as they only have 1 APN, but an edge case for the ones that do have this configuration.

For which one? so far both are option outside iOS and android
