Hi..I currently have a phone with a standard sim and am about to get a new phone with a nano sim. I am going to upgrade my account to go to 4g with more data. When I go to upgrade it states they will send me a new sim for the 4g. How can I tell them it has to be a nano sim. I am guessing they already know my current phone is a standard sim. There is no place on the order form to tell them I have changed.
