We pay mobile operators a monthly fee to use the Internet and make calls. But it's not just our money we're paying with, it's also our data.

TL;DR version:

  • Mobile carriers collect and sell customer data for profit.

  • Carriers use various methods to collect data, including default settings that enroll customers in data collection programs without their knowledge or consent, and opt-in programs that require explicit consent but may use misleading language or design to trick users into agreeing.

  • Major mobile carriers, such as AT&T, Verizon, and T-Mobile, collect customer data through their privacy policies, which often go unread by consumers.

  • Carriers collect various data, including web browsing history, app usage, device location, demographic information, and more. Carriers also combine data collected from customers with information from external sources, such as credit reports, marketing mailing lists, and social media posts.

  • They use this data to create models and inferences about customers’ interests and buying intentions, which they then share with advertisers for targeted advertising.

  • Individuals can choose to opt out of data collection initiatives, utilize Virtual Private Networks (VPNs) to limit data accessibility, and change to alternate Domain Name System (DNS) servers to reduce the amount of data gathered.

    I think that refers to t-mobile’s own/affiliated apps and services. Those would use the onboard ads platform to collect high quality telemetry (assuming the user keeps them installed) but even the lower quality data from outside the platform, like DNS queries, traffic logs, and general device location, can be captured by the carrier if there are no user countermeasures in place.

      It seems confusing to say “Apple users aren’t affected by this” and immediately follow it up with “…and you can disable your Apple tracking ID”, isn’t it? It implies T-Mobile is tracking you through the ID.

      I’m probably overthinking this, and the article is just written a bit poorly.

      Not like the T-Mobile user agreement is much more specific… Like all privacy policies, it makes you guess where things are collected

        Yeah they skipped past some likely questions. I can try to fill in a little.

        Apple users are assigned an advertising ID, but the user can reset (not disable IIRC) the ID whenever they want, so it might not be as useful to the carrier for profiling purposes. All that would give them is fragments of profiles that, without other identifiers like phone or email, might be impossible to associate with their customer.

        Android users tend to have numerous and more persistent identifiers available for profiling, and manufacturers have been permissive with carrier partners re: daemons, kernel extensions, and custom telecom apps. I think that’s what the article meant. Carrier tracking can just be more deeply embedded in an Android system, beyond the obvious bloatware apps and widgets.

        Interestingly, Apple sells similar tracking functionality for specially provisioned commercial devices IIRC, complete with the uninstallable apps, enhanced telemetry, etc. So it’s not like they can’t or won’t track users as a paid service, they just have no reason to let carriers do it on their equipment.

      It does. If you purchase a device from the carrier, it’s guaranteed to be preloaded with their apps. Verizon currently states

      “we may change your wireless device’s software, applications or programming remotely, without notice.”

      The solution is to get a phone from the manufacturer themselves. They don’t come with carrier bloat.

        Agreed, though I might add that a number of manufacturers have been known to dabble in data brokerage as well.

        It might sound paranoid, but Android is built around data collection, and in practice it’s just a feeding frenzy. The carrier, the manufacturer, the ad platforms, the advertisers, the app developers, everyone gets a piece and none take responsibility. This is why I usually recommend a clean flash, Lineage or the like.

        If that’s too technical, I would strongly recommend nontechnical users stick to iOS. It’s not perfect but I hear it’s better lately, and at least it’s not a data free-for-all.
