For the time being, the latest version of our app is available in the following regions:   iOS: Poland only Android: Poland, Belgium, Germany, Ireland, Netherlands   We are considering extending the scope of regional availability to other EU countries. Now, if you travel to Poland from countries other than those mentioned above, or you simply don’t have a Polish phone number, you can ask your friend or relative in Poland to buy the e-ticket for you in the Spark app.   Important to remember: when signing up in the Spark app it is necessary to have a Polish phone number (starting with +48), regardless of the region.
