To verify your phone number, you need to ensure that:

  1. Do not enter the first two zeroes (00) nor the + symbol when entering your number.
  2. For example. If you lived in the United States, the country code would be 001/+1 and the number. All you would need to enter is 15552163.

Once you have added your number, you can also set up Two-Factor Authentication via SMS by clicking here if you prefer receiving an SMS.
