I'm more worried about persistent, authenticated/ID-linked TCP connections (e.g. APNS) providing the client IP over time to an application service provider (e.g. Apple, Slack, Google, Microsoft, et c), that is, city-level geolocation track history via geoip, than I am the ISP or carrier snooping on what websites I connect to.
Every iPhone connects to APNS for push notifications and stays connected, and, last I looked at the protocol, the client certificate was linked to the device serial number. That's quite a geoip tracklog dataset, and AFAIK you can't turn it off.
It's to the point now that to keep my city-level location private from Apple, I'm not putting SIMs in any of my iPhones/iPads any longer, and carrying a battery powered VPN travel router (with a SIM uplink in it) for them to talk to. Super annoying that it has to come to this.
