does using apple maps count against my data plan on my iPhoneX?

1. Under Settings - Cellular you can see the MB-usage of Maps.
2. Under Settings - Cellular you can switch off Maps and you will see whether the app works offline (I assume that no, because it uses GPS to locate your position); if yes it doesn't charge your plan.

The sort answer is yes, it uses data. Depending on long the trip is, the more data you will use.

You asked if Maps uses cellular data. The answer depends on whether you have Maps selected in Settings > Cellular.

• If it is "on" the answer is yes
• If it is "off" the answer is no

You can control cellular data usage by app in Settings > Cellular.

Of course, Maps won’t work if cellular data is off, because it needs data to download the map images and it is unlikely that you can connect continuously to Wi-Fi hotspots as you travel.

Of course. It doesn't get any simpler than "on" or "off". I don't understand the problem.

The problem is that the Maps app requires cellular data. So if you turn off cellular data the Maps app stops working.
