That's already possible, it's just expensive. Remember when the kindles[1] used to have the option for built-in 2G/3G connectivity "for life" to download books from Amazon that you never had to sign up for or maintain or pay for. Until networks dropped support for 2G and 3G in 2021.

I've explicitly bought all my Kindles with that feature. Amazon cheaped out a few years ago and it barely works on my 3rd Gen Oasis, which uses LTE

For small amounts of data transmit only you can do LoRawan with The Things Network for free.

So that started out as unlimited. After people abused it to tether it got dropped to like 50mb of non amazon traffic a month.
