I search for a multicoin wallet with cheap exchanger, like coinomi, but cheaper. Maybe there are more mobile wallets?
I think only jaxx wallet could be alternative for coinomi that support other altcoin wallet for smart phones..
You may also try the cryptonator but never tested it yet i just found this from google that i think also a good bitcoin and altcoin wallet as alternative..
But i suggest to better use coinomi much better i think and safe than the other multicoin wallet..
