Simple black clamshell with big, clicky keys. Build quality is basic but adequate for a backup phone's life.

Its best feature: 1900 mAh gives real weeks of standby, ideal for a phone that lives in a drawer until needed.
Nokia 2780 Flip

Nothing smart, nothing tracked.

Adequate. Calls work, texts send, the flashlight is handy, and the battery outlasts everything else in the drawer.
Nokia 2780 Flip
KaiOS occasionally stutters, but calls are clear, T9 texting is quick, and the essentials — alarm, calculator, maps, FM radio — all work reliably.
