Intro: Roaming charges add up fast if you’re not prepared.
1. Background apps
Maps, email, and social media use data constantly.
2. No roaming plan
Without a package, rates are high.
3. Auto‑updates
Phones download updates in the background.
4. Streaming
Even a few minutes uses a lot of data.
5. When to switch to Wi‑Fi
Turn off roaming unless needed.
Summary: Most roaming bills come from background data and no travel plan.
