By use case
Choosing an eSIM for maps & navigation
If you mainly use maps and navigation, data use is relatively light. Mid-size data is often enough including messaging.
How much data you need
Maps use about 0.1–0.3GB/day; with messaging and search, about 0.5GB/day is often enough.
A rough guide; actual use varies by app and behavior.
What to look for
