I have unlimited data on my iPhone 4S and plan to upgrade to a 5S. I know the current policy says I can keep my data plan, but my question is how to I upgrade and keep the plan since it's a switch from a 3G plan to a 4G plan?
The only info I've found on this is a year old Gizmodo article which states this can only be done in a brick and mortar AT&T store. I'd rather not go to the store if possible. Can this still not be done when ordering online?
I went from a 4S to a 5 ordering online and never went into a store. They automatically changed my existing data plan to the corresponding LTE version.
Same here when I upgraded from a 4 to a 5. Just make sure you select to keep your existing data plan when you place the order.
Was this AT&T's web site or Apple's?
Mine was through Apple. There is little difference between ordering online Apple vs AT&T (except maybe for business or Premier customers with a discount). Apple simply connects to the AT&T servers and should present the same options you have when ordering online from AT&T.
