A phone from 25 years ago would “stay connected” to the network but idle the modem or even shut down higher functionalities beyond the standard connection ping. A modern phone is CONSTANTLY streaming data. Push notifications. Optimised download of music, syncing of photos, emails, chat messages for your 74 different apps in their different protocols.
you have lost the point. the point is not all that apps. the question was about the bare minimum needed for voice over 3G/4G. no push notifications, no music streaming, no apps of any kind. calls, and sms
All of this combined makes a modern 3310 nigh impossible.
does not. a 3310 was not an entertainment center, and a recreation of it wouldn’t either.
Or, you can have it, but it’s not a phone worth having, because all it will be able to do is call, send text messages, and maybe have a basic browser built in…

that’s the whole point
Those devices already exist tho. You can buy dumb/featurephones already. They exist with modern hardware and can last 2-4 weeks…
