Hi sir my docomo number is [protected]. And i lost my password.
I click forgot password link and provide the mobile number and click continue. But it shows
'dear customer, you have not changed your initial pin. If you have forgotten your pin, please contact customer care at 121 (Post-paid & pre-paid) to receive new pin'
Please provide a new password so that i can login again
Thanx
