In this quick guide, we’ll walk you through the steps to check if your SMART SIM card is successfully registered. Verifying the registration status of your SIM card is important to comply with local regulations and ensure that your account is properly registered and protected. Let’s dive into the steps!

You will be prompted with a notification informing you that your SIM is already registered after entering your cell number and validating the OTP (One-Time Password). There is no need to provide any additional information, as your SIM card has been registered previously.

  • Tick the “Terms and Conditions” then click “Send”


  • Enter the OTP that will be sent to you and then click “VERIFY OTP”
  • You will receive a notice that your SIM is already registered
