I have an n9 and I am on Pay As You Go on AT&T. Just went to their office yesterday and they refused to issue a microSIM. They said they can only issue microsims if you have a contract. I tried cutting the SIM card myself, but it was not recognized by the phone. I ordered a cutter which should arrive in about 5 days, and I'll let you know how it goes. In the meantime, I tried using a contract microSIM for an Iphone, and it works. It seems like the chip on the AT&T microsim and the AT&T pay as you go sim are slightly different in size - the pay as you go sim has a longer and slightly narrower chip. I really hope that when I cut it with the cutter, it will work. Otherwise, I'm screwed....
