Installing the Mobile App
You installed the mobile app, and done with your mobile app only password. When you login, it asks for your OTP. But instead of receiving the OTP directly, you received a message from (02) 25678 that you need to reply with ‘ADD DEVICE’ instead. Only then will they text you your OTP.
But replying with ‘ADD DEVICE’ the message failed sending no matter how many times you tried.
