It looks like you are trying to use the Economy Shipping method in the Mobile Phones & Smartphones category.
This shipping method is reserved for accounts with an established history of selling on eBay, as well as to make sure their buyers receive their items on time. As you continue to list items and build your reputation as a seller, this option becomes available.
To continue with this listing, please go back and select a different shipping method.
How I fix this problem, I changed the shipping method to the economy shipping method but this problem again displayed to me.
