Rates read 10 Aug 2026. Where a source publishes a range, the upper bound is used: running out abroad costs more than buying a size up, and in a country that blocks a seller's storefront you may not be able to top up at all.

An estimate from published per-hour figures, not a measurement of your phone. Background updates, photo backup and app installs are extra — the result adds a 15% allowance for them, and the working is shown.
