Your top up code doesn’t expire until you use it. However, the validity of your Pay&Go+ Recharge depends on its amount. The Proximus Pay&Go+ top up, at a minimum amount of €10, extends the validity of your SIM card by 12 months. However, it is possible to recharge your credit for only €5 and your SIM card will be extended by a month. Once your Pay&Go+ card has expired, you will not be able to make calls, send SMS or surf the Internet. Remember to reload your card before or within 7 days after the expiration date
