Buying credits to send SMS messages is very simple. If you are logged in, select in the menu: SMS and then Upgrade. Here you can select and confirm the number of credits. You will get an overview of your order and the possibility to pay via iDeal or bank transfer. If you choose iDeal your credits will immediately be credited to your account upon completion of payment. By bank transfer the credits will credited to your account as soon as your payment is received on our account. This usually takes 1-4 working days.
