With Movistar it should be 210 days without a recharge:

Para todas las líneas celulares prepago: Si el cliente no realiza una recarga en el plazo de 210 (doscientos diez) días calendario, el servicio será dado de baja.

But credit stays only valid for 30 days. I think it's similar with the other providers. So you can take a SIM and refill it with the smallest amount after 6 months (as you will lose it not using it within 30 days) and your SIM should be still alive after 1 year.
