Ordering Credits & Payment Methods

Rayo SMS operates on a transparent, prepaid credit model. To purchase credits, sign in to the Web Application and click Credits in the left sidebar (or click the Credits Left badge in the top navigation bar), then select Order Credits.


  • Prepaid Model: Credits must be available in your account balance before sending live SMS messages (testing with Simulation Mode consumes 0 credits).
  • Pricing & VAT: Displayed per-credit prices exclude VAT. Applicable VAT is calculated and added at checkout based on your confirmed tax profile.
  • Credit Consumption: 1 credit = 1 standard SMS part (up to 160 GSM 7-bit characters; multi-part messages over 160 characters consume 1 credit per 153-character segment) for your destination country pricing.
  • 1-Year Validity: Purchased credits must be consumed within 1 year (365 days) from the purchase date. Any unused credits remaining after 1 year are automatically nullified.
  • No Refunds or Cancellations: All credit purchases are final and non-refundable.
  • Invoicing: Official tax invoices are issued automatically using your confirmed Company Details and sent to your account’s contact email address.

On the Order Credits page, you can choose between three payment methods depending on whether you prioritize instant allocation or zero payment processing fees:

Pay online using any major credit or debit card (VISA, Mastercard) processed securely via Stripe for instant credit allocation.

  1. Open Credits -> Order Credits and select the Online Purchase with Card tab.
  2. Enter the desired Number Of Credits (must meet or exceed the displayed minimum credit purchase threshold).
  3. Review the calculated total amount (including VAT) and the estimated net credits to be allocated, then click the blue payment button showing the calculated EUR amount.
  4. Enter your Cardholder Name, Card Number, and Expiration Month/Year to complete the payment.
