I often ditch my phone and carry my hotspot device for my internet. The only drawback is that for viewing my texts and OTPs i end up putting the sim in my phone or opening up the web interface on my laptop. This seems to work very well as a dumbphone per se.
How do you check sms/OTP/text using web interface on your laptop?

It so happens that I’ve just bought a $10 4G dongle [1], guess I’ll have to check what’s inside now :-) [1]: like this: https://img.joomcdn.net/ea91b4418997d83d802339fad0bbcf878b9d... --- Aside, but it appears some MSM8916-based dongles run Android UI despite having no display: https://github.com/u0d7i/uz801#screenshots

#35It would be pretty cool to put Hermes Agent or some agent system on that thing, assuming the OpenStick build has enough RAM/storage. That would be fire.

Truly, I couldn't imagine a worse platform to put a coding agent on. What even would be the point? It's got less than 512GB of RAM, no package manager, and virtually no storage.

My biggest tip is to carefully back up every partition of the original firmware - there are many many seemingly identical variants and if you hose your particular baseband components you will lose your cellular functionality.

it's most likely UZ801 (mentioned in the article)
