Why Carrier Settings Matter Right Now
A Show HN post titled "iPhone, Pixel and Galaxy carrier settings decoded" hit 410 points and drew 49 comments in a single day — nearly a thousand total interactions. That is not idle curiosity. People were arguing in the thread about which carriers disable personal hotspots, which ones throttle roaming data, and why the same SIM behaves differently on an iPhone than on a Pixel. Every one of those arguments was about a file that is publicly downloadable and almost completely unreadable.
The existing options do not solve this. Apple ships carrier bundles as binary plist files that require a decoder to open. Google publishes apns-conf.xml for Android, but it covers only one platform and says nothing about the iPhone sitting next to it. Carrier support pages describe a single operator's APN values and never mention a competitor. Reddit threads contain real experience, but they are scattered across subreddits, unsearchable, and outdated within months. Nobody has built the layer that sits on top of all of it: a searchable, comparable, plain-English record of what each carrier actually ships.
The timing is what makes this worth building now. The decoding problem was solved by the original tool — the hard part is done. What remains is the data layer: collecting the public configuration files, translating the keys into human terms like hotspot allowed, VoLTE enabled, roaming data default, and MMS size limit, then diffing them across devices. That is a weekend of work with a static site and a JSON file, and the audience is already gathered and asking questions in public.
How It Works
Upload or pick your carrier
Drop in a carrier bundle file such as an ipcc, carrier.plist, or apns-conf.xml, or simply choose your carrier and device from a dropdown covering Verizon, T-Mobile, Vodafone, China Mobile and the other operators people ask about most.
Read the plain-English table
Every raw key is translated into a field you can actually understand: whether the personal hotspot is permitted, whether VoLTE is on by default, what the roaming data setting is, and what the MMS size ceiling looks like on your plan.
Compare and share the diff
See the same carrier side by side across iPhone, Pixel and Galaxy with differences highlighted in red and green, then copy a permanent link or export a Markdown table to post straight into a forum thread.
What You Get
Plain-English Decoding
Raw plist and XML keys become readable fields. Instead of guessing what allowHotspot or roamingDataDefault means, you see a sentence describing exactly what your carrier enabled, disabled, or capped on your specific device and plan.
Cross-Device Diff
The same carrier rarely ships identical settings to every phone. CarrierDiff lines up iPhone, Pixel and Galaxy configurations in one table and highlights every difference, so you can see at a glance where a feature was quietly removed on one platform.
