Verizon setup ISIS on my Note 3 at the time of my purchase. The first time I tried to use it, I didn't realize that I hadn't added the American Express Serve card (with the $25 free money added). The second time I tried to use it I couldn't get it to work...However, S-beam was off and now I keep it on. Both times above I gave up and paid with my card...so I am still waiting to try it for the first time.
As far as Google Wallet goes...I just downloaded the app from the Play Store. I will mess around with it after work to see how I can get it to work. Already though it tells me about the most recent purchases I have done with Google even the free ones.
