I just placed an order for two sims and I am on a SERO plan. The only four questions I was asked via chat was: my phone number, email address, which model, and address. I checked my order status and it is not being listed. I am giving the Sprint system a little to process it. She mentioned it might not ship until the 8th. No big deal.
*UPDATE* Order went through showing "LTEGSM REMOVABLE 3FF USIM" under Description.
