Mango covers 200+ countries across Europe, Americas, Asia-Pacific, Africa, and the Middle East. Each plan lists coverage on the shop page. If a destination is missing from a regional bundle, Nomad usually has it.
Wholesale data in Mexico and the UAE costs more than the rest of those regions. Including them would raise the whole bundle. Both are on the Nomad plan (200+ countries). The shop flags this when you pick Americas or Africa & Middle East.
