Purchase and payment method After choosing the number and agreeing on the price, an electronic invoice is issued to the buyer in his name, including the mobile number requested and its total value, and ownership transfer details. The invoice and payment link will be sent to the buyer's mobile via SMS and to his email. Payment can be made electronically via Mada, Visa, or Apple Pay. After confirming successful payment, the ownership of the number is officially transferred to the buyer's identity via the mystc app. All stages of the process are documented with the invoice, proof of successful payment, and completion of ownership transfer.
