SIM guide
Understand your usage before you choose.
A SIM plan can look simple, but the right fit depends on how you use data, whether you travel, your contract preference and what changes after any introductory period.
Light-use profile
Suitable as a starting point for people who mostly use messaging, navigation, email and light browsing. Check whether background app activity or occasional video means you need more headroom.
Everyday-use profile
A useful starting point for regular social apps, web use, music and some video. Review actual monthly data use in your phone settings before deciding.
Heavy-use profile
Consider this profile if you stream frequently, tether another device, travel often or rely on mobile data as a primary connection.
Questions worth asking
- Is the data allowance enough for normal and high-use months?
- Does the plan include roaming where you need it?
- Is there a minimum term, and what happens at the end?
- Are there speed caps, fair-use rules or hotspot restrictions?
- Can the monthly price change during the contract?
- What are the cancellation or early-termination rules?
