Arattai asks you to set up your primary device when:
  • You log in for the first time
  • Your account does not have an active primary device
  • You reinstall Arattai
Note: SIM binding is required only for the primary device. Companion devices do not require a SIM.

  • Your registered SIM is in the phone and active
  • Your mobile plan can send SMS
