The way the post before mine was written I think I have my answer, but I just wanted to make sure. I am currently in the process of waiting for my physical card for ISIS. I signed up through the app and everything seems to be set up correctly. When I activate my physical card on the Serve website will my limits change at that point or do I need to do anything else inside the ISIS app? I am hoping to trade in my 5S for the new iPhone this weekend and my physical card may not be here till the beginning of next week...so just wondering if I need the app anymore once I've signed up.
