Who we are
Odyssey Global SIM is the travel connectivity brand of Acorn Enterprises, based in the United Kingdom. We supply physical SIM and eSIM cards that keep you connected at home and abroad without roaming charges — for individual travellers as well as businesses and travel agencies.
Odyssey Global SIM is a smart SIM that gives you mobile data in more than 240 destinations worldwide, at affordable rates and with no roaming charges. Our mission is to make global connectivity simple, affordable and instant, so that travellers can focus on exploring, not on searching for Wi-Fi or a local SIM. Our vision: to be the leading provider of international travel services and global travel data.
Data only, calls through your apps
Odyssey Global SIM is a data-only service: you make calls and send messages through apps such as WhatsApp, Viber, Telegram, WeChat, LINE and Facebook Messenger.
Our data plans work on any network-unlocked device, so you can keep your usual physical SIM card. And because Odyssey Global SIM is reloadable, one SIM serves you trip after trip. Never alone — that is the promise we make to every traveller. Travel smart: get Odyssey Global SIM today.
