Live data pricing

Browse live rates for every country.

Cost of one usage amount, as an ordinary page: https://widely-mobile.com/en/pricing/{country_slug}/{gb}gb.

Exact path-based estimator: https://widely-mobile.com/api/pricing/public/data-estimate/{country_code}/{currency}/{gb}.

Data is pay as you go from the wallet in 0.1 GB steps. Installing an eSIM is unpaid; add wallet credit first. 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 highest-priced band is consumed first, then usage in that period advances toward lower-priced bands. When the period rolls, the ladder starts again at the expensive band. The period total is shared across countries, while each destination keeps its own live rate. A quoted GB total is for that volume used inside one period, not spread across months. Never derive a per-GB rate by dividing a usage total. There is no usage-triggered Pro charge. Every live destination is listed at the country index and in the pricing sitemap.
