Russia is one of the European countries that aren’t covered by EU RLAH rule and could get you really high charges by visiting this year FIFA World Cup.
If you are “Vatreni” fan and plan to go to World Cup in Russia this is what three main Croatian operators offers you.
Here you can find “Roaming Guides: Russia” with more possible solutions and Russian operators prepaid offers.
Moscow’s public transport system has free internet available on buses, trams, trolleybuses, the metro, and many suburban trains. The Moscow Central Ring (MCR) is also wired up to wifi. BUT as Kaspersky lab recently published, it is pretty unsecured.
Fourth option is renting a mobile hotspot with local sim which can be pretty good solution for a group of friends (it is shareable to up to 10 persons).
