What is a contact number and why do I need one?

A contact number is a mandatory, alternative phone number required when you create your Tello account or place an order. It serves as your primary security backup and communication lifeline.

Why Do I Need One?
  • Essential for Account Security: For your protection, our Customer Support team can only assist you with sensitive, account-related requests if you call us directly from your active Tello number or this registered contact number.
  • How We Reach You: If your Tello line is ever unavailable, inactive, this is the number our team will use to reach you regarding critical account updates, security or order verifications.

What to do next:
  • Choose an accessible number: Pick a phone number that you can easily access whenever you need to receive a call or contact us.
  • No second number? If you don’t have another personal number, you can enter the number of a trusted friend or family member.
  • International numbers are welcome: If you only have an international phone number available right now, you can absolutely use it as your contact number.

⚠️ Important Note: This field cannot be left blank. You must provide a valid working contact number to successfully finalize your order or account setup.
