# BlueGo > BlueGo is an eSIM marketplace for international travellers. We sell prepaid mobile data plans (eSIMs) for 190+ countries — from small GB packs to unlimited data — that activate instantly with a QR code, with no physical SIM card and no contract. BlueGo also offers Flight Protection, which automatically claims compensation for delayed or cancelled flights under EU Regulation EC 261. ## What BlueGo offers - Prepaid travel eSIMs for 190+ destinations, in local data plans (fixed price, paid up front, no roaming surcharges). - Single-country and regional eSIMs (e.g. a regional Europe eSIM covering many countries with one plan). - GB packs and unlimited-data plans, so travellers can match data to their trip. - Instant delivery: after purchase you receive a QR code and a one-tap install link by email; activation is immediate. - Flight Protection: automatic monitoring and EC 261 compensation claims (up to €600 per eligible flight), powered by AirHelp. ## How an eSIM works - An eSIM is a digital SIM built into modern phones (iPhone XS and newer, Google Pixel 3 and newer, recent Samsung Galaxy, and many others). - You keep your normal SIM/number active for calls and texts while the eSIM provides mobile data abroad (dual SIM). - Install the eSIM over Wi-Fi before travelling; data validity begins when it connects to a network at the destination. ## Data guidance (typical one-week trip) - Light use (maps, messaging): about 1 GB. - Moderate use (social media, browsing): 3–5 GB. - Heavy use (streaming, frequent video calls): an unlimited-data plan. ## Key pages - [Home](https://bluego.io/en): overview and destination search. - [Destinations](https://bluego.io/en/destinations): browse eSIM plans and prices by country and region. - [How to activate an eSIM](https://bluego.io/en/activate-esim): step-by-step activation guide for iPhone and Android. - [FAQ](https://bluego.io/en/faq): answers about eSIMs, devices, data, payment and Flight Protection. - [Flight Protection](https://bluego.io/en/flight-protection): flight delay and cancellation compensation. - [Blog](https://bluego.io/en/blog): travel connectivity guides and tips. - [About BlueGo](https://bluego.io/en/about): who we are. ## Languages The site is available in English, Spanish, French, German, Italian, Chinese and Japanese (e.g. https://bluego.io/es, https://bluego.io/fr, https://bluego.io/de, https://bluego.io/it, https://bluego.io/zh, https://bluego.io/ja). ## Company BlueGo Solutions OÜ, an EU-registered company based in Tallinn, Estonia (VAT EE102989498).
