Enabling airplane mode on your device does stop your phone from actively transmitting your location. It disables all wireless signals, including cellular, Wi-Fi, and Bluetooth. However, it's worth noting that this does not necessarily mean that your phone is completely disconnected from the network. It's possible that your device could still send certain data if it's connected to Wi-Fi or Bluetooth before Airplane mode is switched on. Additionally, if your phone is already being tracked by a third-party app or service, enabling Airplane mode will not necessarily stop that tracking completely. Therefore, it may be wise to disable location services and revoke app permissions if you want to ensure that your location is not being shared.
