Most issues with delivery of SMS with the authorization key are resolved by using the “Resend SMS” button. If you do not receive the SMS within a few seconds, press the “Resend SMS” button to have a new key sent via an alternative route. After the third time you press the button you will receive a call where the key is read to you in English.
If this does not resolve the issue, failed delivery could be due to other causes.
Incorrect registered phone number
Is your registered mobile number in the correct international format? In many countries there is a difference between local and international format. For instance, within the UK numbers should start with 0, but when calling or texting the number in the international format, one must use the international prefix (44) and remove the leading 0.
Contact Admincontrol support to edit your registered mobile number.
Other causes to failed delivery
Other causes of failed delivery could be carrier spam filters incorrectly filtering legitimate SMS traffic, or roaming issues due to lack of interconnection agreements between carriers in different countries. If you frequently travel abroad SMS might not be delivered to you as a result.
