Troubleshooting guide for Tapo 4G camera

What do you do if the SIM card doesn’t work with your Tapo 4G camera?

Make sure the SIM card is a Nano SIM card that supports LTE-TDD/LTE-FDD. And the supported frequency bands are LTE-FDD: B 1/3/5/7/8/20/28 and LTE-TDD: B 38/40/41.
Some SIM cards have a PIN code. Insert the Nano SIM card into your phone to disable the PIN first.
