Does my European SIM card guarantee unrestricted roaming in Mayotte?

While Mayotte, as a French Overseas Department, falls under the EU's "Roam Like at Home" directive, relying solely on a European SIM for data-intensive usage can be problematic. Many EU carriers implement "Fair Use Policies" (FUPs) that significantly cap data allowances in overseas territories or impose strict speed throttling once a minimal threshold is met. This can severely impact productivity and communication for heavy users. DataESIM offers dedicated, high-volume plans for Mayotte, ensuring consistent 4G/LTE speeds without FUP-related limitations, providing a more reliable and performant solution for digital nomads.
