The day after I received my n4 I had calling issues. So I used my work phone to contact T-Mobile. They needed me to remove the Sim. I told them I didn't have the stupid extraction tool for the tray and they told me to just use a paper clip. I did and I was terrified that the dang paper clip nearly got stuck inside the pin hole. Wow. I just don't know what to say. I wish Google had developed the Sim tray better. I mean, do I need to carry the extraction tool around with me in case I need to remove the Sim card?? Just tuck it in my wallet?! I mean really? Oh well.
