Right now I have a iPhone 5 but I`ll cange it with M8. So, can I use my nano sim with the HTC One M8 or I should use the one that comes with ? Verizon tells me if i activate the new sim, my old one will expire, but what I know is that the new SIM has to be used if I want to use NFC . To be honest, I don't care if NFC won't work, but I want to know if I can use this sim or no .
