The SimpleSMS.hu SMS sending service operates on a prepaid balance system. To send SMS messages, you must first top up your balance; the system will then automatically deduct the cost of the messages you send from that balance.

If your balance runs out, SMS sending will automatically stop and can only resume after you top up your balance again.

At SimpleSMS.hu, we use a prepaid payment system. This means that in order to send an SMS, you must first top up your balance. We offer various payment options for this, including credit card (Stripe) and bank transfer. All methods are secure and fast.

We always bill you based on the top up balance you provided when buying the service, and you can send SMS messages using that balance. If your balance runs out, the system will not allow you to send any more SMS messages.
