I have two cards on my S6 Edge phone, have had for a long time. But on the Gear S2 I can't add the second card. Oh well. At least I have the card I use the most on it. Now getting it to work might be another matter. I tried yesterday at the grocery store it it didn't work. But then again, I have had my phone not work either at that store. Most of the time it does work there. I will just try again the next time.
