What is the sim card/usage for?

[Gellie]

Hello, what exactly is the sim card used for? If i'm on WiFi why would I need it? Is it a back up if the WiFi is down or off line? Is there a charge from ATT if I activate it(ie Ipad). Thx

The SIM card is only for the Arlo Go, which uses cell service for the Internet access. No other Arlo camera uses a SIM card.

Does that pro support wi-fi too or is it ONLY 3G/4G cell service? For example can we have the wi-fi as a backup or vice versa?

Only cell service, now available via AT&T and Verizon.
