How much data do I need, and can I top up?
Estimate your activities and check allowance, validity and top-up rules separately.
Estimate by device and activity
Start with your sea days and expected messaging, browsing, photos and calls. Our calculator provides a planning estimate, not a guarantee of consumption.
Check top-ups before relying on them
Top-up availability and expiry rules depend on the supplier. Adding data does not necessarily extend validity. This preview does not sell top-ups or provide live usage reporting.
