Off topic, but I noticed today that all the major US carriers now charge a premium for their SIM cards. They all want me to pay $10 just to walk out of their store with a SIM and no plan. AT&T was nice enough to discount it with an in-store coupon. But MVNOs don't seem to do this; their sims are $1 or free.
