The RUIO Joy released a week ago but it’s just starting to reach store shelves (currently only in JB Hi-Fi).
It runs Android 11 with no Google services, has 4G that works on Australian networks, and has similar specs to the Cat S22 Flip (slow quad-core CPU, 2GB ram, etc.)
If disconnected from services and hardened it’s not terrible.
Medical devices ship this way.
At the price I’d wager that sufficient hardening of the OS hasn’t been done, but if it doesn’t allow banking / shopping apps and just is for calls and email and text your threat model is real niche.
