Where is low data mode?
Low Data Mode is one of the deepest settings we measured, and on most systems it is set per network rather than once for the device. We read the settings tree of all 43 systems in the catalogue and recorded where each one keeps it.
What each system calls it
15 of the 43 operating systems in our catalogue have this setting, and they agree almost completely on what to call it — only two spellings appear at all, and Low Data Mode covers 14 of them.
That is rarer than it sounds. Across the settings we have measured, most concepts carry four or more names; this one is an exception worth noticing.
Where it lives on each system
These are the shortest paths from the first settings screen on the newest release of each system. 1 of the 15 are within two taps; the rest sit deeper, and the table shows how much deeper.

Each system name above opens the real menu in the simulator, so you can walk the path before you touch your own device.
Why the names came out this way
That per-network design is why it is so deep: you are not setting a system preference, you are editing the properties of one Wi-Fi network or one mobile plan. The path runs through the network list, then through a specific network, then to its options.
It is also why people turn it on once and forget it. A connection that feels slow on one network and fine on another is worth checking here before blaming the signal.
Find it on your own device
If your system is not in the table, or the label on your screen is different again, there are three ways through it:
- Search every system at once for a setting by name — it looks inside all 43 trees, not just the one you are holding.
- Open your own system in the settings simulator and click to the screen without changing anything real.
- Follow the step-by-step guide to adding an eSIM, or see where that setting lives on every system.

Where is low data mode on most systems?
On 1 of the 15 systems that have it, within two taps of the first settings screen. The most common label is “Low Data Mode”, used by 14 of them. The table above gives the exact path for each system.
Why can I not find it by searching my settings?
Because settings search matches the label your system uses, and the label may differ from the words you are searching for. Searching for the word your previous device used is the single most common reason a setting appears to be missing.
How many systems have this setting at all?
15 of the 43 operating systems we catalogue. The rest either have no hardware for it or fold the behaviour into something else, which is why a feature that feels universal often is not.
