What are the best options for people like me who live in the USA and want a physical SIM for carriers like Verizon prepaid and traveling?
Drive across the border into Canada or Mexico? It looks like you might be able to order online for in-store pickup.
Another interesting thing I noticed is that Guam and the US Virgin Islands get the same iPhones as Canada and Mexico. Except Apple doesn't have a store there. On their website it says, "We are happy to ship your order to a friend or family member residing within the 50 United States if your billing address is within one of" [those territories]. So does that mean if you get a billing address in Guam or the US Virgin Islands Apple will ship you the physical SIM iPhone to your address in the US?
