Todos los clientes que se den de alta o tengan activa una tarifa Mundo Total disfrutarán de 15 GB de regalo con una recarga de importe igual o superior a la cuota de su tarifa hasta el 29/02.

All customers who activate or have an active Mundo Total rate will enjoy a 15 GB gift with a recharge of an amount equal to or greater than their rate quota until 02/29.

That means technically, it's for a top-up of €15 or more if you are on Mundo Total plan. They do it through their bonus scheme recagar y ganar, as far as I know. It doesn't apply to you, if you have charged the monthly rate on an existing balance on your SIM.
