@Elizabet_113990 Take a look at your account dashboard first to see if the sim is still activated.
normally, you would have a total of 220 days until a sim is deactivated - you should receive an email after 180 days warning that it will deactivate in another 40 days if no money is spent.
If it is in fact active, you can simply buy one of the Smarty plans and then either let it auto renew in your account dashboard, or else do it manually each month or whenever suits (subject to the time limit I already mentioned).
