11 Best International Roaming Plans Compared for 2025

7. Airalo eSIM marketplace

Airalo operates as a marketplace connecting travelers with many regional and global eSIM sellers. That means extreme flexibility: you can buy a short city pack, a regional bundle, or a global package depending on your itinerary. Airalo often has competitive pricing, and multiple seller options let you pick based on data amount, price, and validity. Activation is generally handled through the Airalo app with QR codes or integrated installs. The marketplace model gives you granular control, but it requires you to research the best pack for each country and watch validity windows closely. For North American travelers visiting India, Airalo can be a good way to buy an India‑specific pack that’s cheaper than roaming. Pros: flexibility, many pricing choices. Cons: choices require comparison, voice is app‑based. Best for: budget-savvy travelers who plan per-country data needs.
