Network connection and Ocusyc 2.02 Help

When flying with my MV2 connected to a Huawei MatePro 6 + 128 Tablet via the DJI stock controller - Does the tablet have to have access to a mobile sim. IE connection to a network?
I can piggy back my mobile phone onto my tablet. BTW no disrespect to pigs. Thanks
My cell is a new Huawei P40 with Android 10 - Tablet also has Android 10.
I’d also like to ask how Ocusyc 2.02 works - can’t make head or tail from the spec given on DJI website. Replies much appreciated regards A Jock in a Box
