A security PIN is a 4-digit number that enhances the security of your Tello account. It is essential to set up a Security PIN as soon as possible after creating your Tello Account.
A security PIN is a 4-digit number which serves as an extra security feature, granting you exclusive access to request specific account changes, such as device changes, SIM changes, port-outs, and account deletion.
It's important to note that the Security PIN does not replace the password of your online account and it is distinct from the port-out PIN required when leaving Tello and porting out your phone number.

If you cannot recall your Security PIN, you can reset it anytime from your online account (not the "My Tello" App), with the "Reset Security PIN" option. You'll receive a reset code via SMS. After receiving the reset code on your phone, return to the "Reset Security PIN" section and input the code under the "Reset Code" field. Proceed to set up your new Security PIN.
Please note that the reset code serves as a temporary code only, that facilitates the setup of a new Security PIN, for your convenience.
