You can already buy those. They seem to commonly be referred to in online stores as ‘pocket wifi’. Just stick a sim card in them and you can manage their settings through any connected device with a web browser.

I can vouch for Floorp being quite good. It also seems to be faster than Waterfox despite having more features built in.

Many people do think using words through their inner monologue.
