It's an EOS wallet not ESO wallet for correction, I think there is no freebie on creating EOS wallet you need some EOS just by creating a wallet. But in some existing wallet like imtoken you can create or activate an EOS account but not paid directly by EOS coin but instead of Eth sounds odd but its true. Unlike other network you just need to pay for a gas before you can make any transaction .while EOS is a quite different u need to buy or stake for RAM,NET and CPU before you can make any transactions that's why for the EOS first time users its a little bit complicated.
