After testing across dozens of trips covering 150+ countries across Europe, Asia, Americas, Middle East, and Africa, Yesim consistently wins for multi-country travel. Coverage is reliable in all major tourist areas, prices are competitive, and the app makes activation simple. For budget short trips to a single country, Airalo's country-specific plans often undercut Yesim on price.
The key differentiator is coverage depth. In less-visited areas — rural Portugal, Albanian coast, Georgian highlands — Yesim's 150-country network tends to have stronger local partnerships than the more basic plans.
