The only free EOS wallet is the EOS wallet in the exchanges.
Try to search for Eosex, maybe you can create there and try to trade your EOS also at the same time, I just joined their bounty of EXP and I think you can use their platform for your tokens.
That's one of the exchange dedicated for EOS tokens, they recently did an ICO in this bear market and still was successful. its the only you have if you want free. Its hard to trust an exchange though.
