Instabridge

Instabridge started in Stockholm in 2012 as a crowdsourced WiFi password app, the kind of thing you'd open in an airport lounge to avoid paying for hotel internet, and it built a genuinely large database of shared hotspots over the following decade. Rather than launching a separate brand, the company added a travel eSIM directly into the same app, so existing users get an obvious upgrade path from free WiFi to paid mobile data without downloading anything new.

The eSIM itself lists 118 countries on its global plan, smaller than the 190-plus Instabridge sometimes claims in marketing, so it's worth checking your specific destination is covered before buying. Pricing runs on fixed data packages rather than a subscription, for example 1GB over 7 days for around $8, or 10GB over 30 days for about $50, and it's strictly data-only, no voice or SMS, with calls better handled through a VoIP app. Refunds are handled manually by email with proof of purchase rather than an automated in-app flow. It's a natural fit for existing Instabridge users who already lean on the WiFi map and want one app that covers both free and paid connectivity.
