How to Unbind Your Phone Number
There are two scenarios for unbinding:
Scenario 1: You Can Still Receive Verification Codes
You can unbind your phone number via the Security page on the Web.
Scenario 2: You Can’t Receive Verification Codes (e.g., SIM Deactivated)
If your current phone number is no longer active and you are unable to receive SMS codes, you can request to unbind via one of the methods below:
- Use the security reset form and submit the required information. You’ll receive a response within 1–3 business days.
- Send an email to support@gateio.jp explaining your situation. Please include your Gate account username and UID, registered email address, full name, city of registration, traded currencies, the phone number linked to your account, and a photo of yourself holding your ID along with a handwritten note that includes your Gate UID, the statement “Disable SMS”, the date, and your bound phone number (as shown in the example below).
