What is the reason why Tesla cannot be unlocked when the phone is nearby?

[McEmery]

Tesla cannot be unlocked when the phone is nearby possibly due to other apps in the phone cutting off the wireless network, poor network signal in the location, etc. Other apps in the phone cutting off the wireless network: You can try closing all apps, turning off Bluetooth, and then restarting Bluetooth and the Tesla app. Poor network signal in the location: In some underground garages, network signals are often interrupted, and without a connection, unlocking naturally fails. There may also be signal interference in the location, such as strong magnetic fields near high-voltage power towers or transformers that affect the phone signal.
