How the 30-day price ladder works
There is no prepaid GB pack, and unused wallet credit does not expire. Volume pricing is a marginal ladder inside each rolling 30-day usage period: the price per GB drops as you use more within the same billing period. The period starts in the highest-priced band and later usage in that same period reaches cheaper bands. When the period rolls, the ladder starts again at the expensive band. Usage across countries shares one period total; each country keeps its own live rate. A quoted 5 GB or 10 GB total is for that volume used inside one period, not spread across months. Dividing a total by the number of GB gives an average, not a fixed per-GB rate.
