> But for that you can also use a Nokia 3310, not spend hundos on an iPhone.
You don't have to spend anything if you already have that device. For instance, it could be a hand-me-down from a relative. In my family, we do have an older Android 2.x device which is currently being used as just a phone (for calls, SMS, and yes, an oversized clock); it has passed through the hands of three people already, and only the first of them used the smartphone functionality. After that, it was factory reset and never connected to a data network again (because it would then try to update all built-in apps... and that tiny phone simply has not enough storage for all these updates). It works perfectly as a phone.
