iPhone 7 Sim Switching, Account Switching or just Normal Domain Traffic? I think there is some funny business going on with one of the devices in my house.

I'm not sure if the person is changing into between iCloud Accounts on the same device, or switching Sims or using multiple Sims on an iPhone 7 or not? It just seems strange and I'm trying to get to the bottom of it.

I'm seeing patterns like this below. I think some might be add networks but I'm seeing a lot of the certificate stuff. Here's an example in order.

6:18PM - ocsp.godaddy.com

6:18PM - ib.adnxs.com

6:18PM - prg.kargo.com

6:18PM - match.adsrvr.org

6:19PM - match.adsrvr.org

6:19PM - sync.mathtag.com

6:22PM - ocsp.apple.com

I see the ocsp domains a lot along with items like;

ocsp.digicert.com

sr.symcd.com

inet.ess.apple.com

Just wondering if any of the above will show up a lot if;

the device is being restarted

a new sim is being initiated

or if an apple id account is being switched between
This looks like normal advertisement and certificate network traffic to me.

A SIM card swap, device restart, or Apple ID login wouldn't/shouldn't produce traffic to ad servers. A device restart might ping OCSPs (Online Certificate Status Protocol), but it makes more sense for that to be checked by a browser when visiting a website.
