I don't think bitcoin is synonymous with mobile payments. Bitcoin is a currency (or asset value), but not an infrastructure to make mobile payments. The proper comparison would be the blockchain. The blockchain is what facilitates mobile payments in the bitcoin world. And to be fair to the leaders in mobile payments, they are still (as in it's possible) to include bitcoin in the currencies they allow to be exchanged using their service. The challenge is that google pay, paypal, etc. would have to engage in the blockchain themselves to facilitate payments. This is much harder than merely transacting in Euros, Dollars, or Yen.
Give it time, bitcoin will either exist as a larger player with the blockchain being the mobile payment infrastructure or major mobile payments providers will find a way to transact in bitcoin. The trigger for the latter is having a significant enough volume of bitcoin transactions for the companies to realize they can make money at it OR leave money on the table by ignoring it.
Everything will run under the blockchain which implies a higher price in Bitcoin. People will be making transactions without being aware they are even using Bitcoin. Bitcoin will be the "brains" under every electronic transaction in the future. Thats why anyone not owning some now is missing the big picture.
