FAQ
Mobile calculator questions
How do I compare SIM-only vs handset bundles?+
Enter a handset repayment if the plan includes a device. The calculator adds it to the monthly plan cost so you can compare the bundle against SIM-only offers.
What if my bonus data expires?+
You can model the bonus period by keeping the data in place, then rerun the calculator with the bonus set to zero to see life after the promo ends.
How should I handle roaming?+
Estimate the number of international roaming days you expect each contract period and the cost of a daily pass. The calculator spreads that cost over the contract so you don't underestimate your spend.
