No cell phone is protected from Stingray or other fake cell towers used to capture and route cellular telephone connections. There is no way to reliably even know if you‘re connecting to such a cell tower. As far as any cell phone (iPhone or other) knows, it’s simply connecting to the available cellular towers in the area.
While there were several (Android) apps claiming they could detect the false network towers , those have now been shown to not work, as the imsi capture technology used by law enforcement has changed so they remain undetectable.
At present, there is nothing any cellular telephone user can do to protect themselves from being monitored by systems like Stingray.
