Fwiw, just because a dumb phone doesn’t give you access to “smart” features doesn’t mean the capabilities aren’t present on the phone. It’s just a matter of what could be hidden on the circuit board (lots can be hidden in chips), and what can be hidden in usual expected traffic (if bandwidth requirements are low, even timing of packets could be used to encode hidden data that would never show up in any logs).
Plus the simple tracking of cellphones is necessary for them to function at all.
