It looks like you can get the Nokia 3310 Cell phone for free if you buy the Cricket refill card plus sim card activation kit shipped free. Note that the refill card is not activated into the sim card so you can use the refill card into your existing cricket plan.
So if you buy the $10 sim card, $25 refill, you get the Nokia 3310 phone for free if you add the 3 items in the cart. If you have trouble adding the phone into the cart, search for "nokia 3310" and add the item there.
