Well it's the same game with same decisions so yes but I find the mechanics difficult on a phone. It is also hard to sometimes see all the data and cannot really multi-table or you have to do it with great difficulty.
Yes, it is possible, cell phones are very advanced today, and on the internet you can find sites and forums to evolve, such as “CardsChat”. If you take a good look at the topics you can evolve a lot.
So far as learning, you are going to have all the same resources available to you on your phone as you would on the computer with the possible exception of solvers.
I think the thing that is going to limit you the most while only playing on a phone is going to be the amount of volume you can put in. Once you become a winning player the thing that is going to increase your hourly earnings the most is your ability to multi-table easily.
I have a friend who combined his main job (worked in a household appliance service) and played on the phone and quite successfully, so everything is within your power - why not
