I received my passport book a week ago now however my passport card is still yet to arrive despite it the dfa sending it the day after they posted my passport book. Should I be concerned? This is postage to the Uk, An post tracking says it left the Dublin mail centre on the 15th yet still no sign.

Hi guys, i'm a citizen via FBR. In the process of applying for a passport, does anyone know if it's okay to use a mobile phone bill as proof of address?
