I've noticed that when I travel, I get spam calls from the area code I am visiting. I have asked my cell provider if they monetize my location data, and they swear they aren't. But I don't trust them, given that no one else (other than Apple) would know where I am in real time. Recently switched providers and haven't experienced it since then. Wouldn't be surprised if there was a class action lawsuit someday.
Of course, this doesn't require having GPS location, just cell tower info is enough.
I'd be looking at ad networks rather than telcos in this case. https://www.eff.org/deeplinks/2026/01/google-settlement-may-...
Use a VPN next time.
Does it still happen?
Name and shame. Which provider were you having this experience on? (If you don't mind sharing since you're no longer with them.)

Literally every website and app you use with any kind of shared analytics/ads gets your general location just from your IP address alone, and can update your profile on that analytics/ads provider.
It is far more likely this, than your cell phone provider.
