Limits to know
- You can top up an active plan as many times as you want.
- Top-ups expire when the underlying plan expires — they don't extend the validity unless you specifically buy validity extension.
- Top-ups only work on your CURRENT plan. If your plan has expired, you'll need to buy a new one.
