Currently, we do not have this feature on our Exchange, please send us an email to email@example.com requesting your phone number to be changed.
When we receive your email, we will send you a code. You will need to send us a selfie with the code provided and the ID you used to get your account verified on our exchange.
This way we'll be able to confirm your identity and securely exclude your old phone number so you can update it!
Note: Once the phone number has been excluded, your account will be blocked until you enter the new number.
