Instabridge

Instabridge began as a Wi-Fi finding tool and evolved into a full travel connectivity platform. Their eSIM offering covers 190+ countries with traditional prepaid plans and a pay-as-you-go tier that charges only for data you actually consume. The same app that finds free networks now manages your eSIM, so switching between Wi-Fi and cellular is smooth from one interface.

This works best for travelers who value an established community and network database alongside their mobile data. The pay-as-you-go model suits those taking unpredictable trips or passing through countries briefly where a full plan would be wasteful. Instabridge's legacy in Wi-Fi mapping means strong coverage info in crowded cities and airports.
