Error in obtaining password via SMS.

Me too. It didn't show up until I changed my password. I didn't receive it until I changed my password. Mobile has opened a lot of business for me. It should be time for you to go to the business hall to charge the phone bill. They record your number and order business for you privately in order to get commission. If the business password of your number is initial, they know it and can order business for you. If you change the password, they don't know. Entering the previous initial password will display the password error.
