SIM Card not fitting
My iPhone 5 Micro SIM card fits perfectly, with a snap, in its tray. I can turn it upside down, and the sim will stay. However, when I transferred it to my iPhone 6, the SIM card- while fitting inside the tray- would not snap in. When I turn it upside down, it falls out as well. Is this a problem or can I still use it as is? And if it is a problem, how would I fix it? Thank you
iPhone 6, iOS 10.3, null
