Step 5 : Now, you need to verify this OTP received on your new mobile by calling ‘1502’ from your existing BSNL telephone number [Landline / Bharat Fiber (FTTH)]. The OTP will be valid for 24 Hrs only. It means, you need to call 1502 from your BSNL Landline / FTTH number within 24 Hrs of generating OTP on your new mobile number.
To verify new mobile number customers need to dial 1502. If you are not getting connected to 1502 from your BSNL landline / FTTH, you may dial 1800-599-9954 (For East & South Zones) or 1800-180-1502 (For West & North Zones).
After successful OTP verification, your new mobile number will be updated in BSNL system and you will also receive a confirmation SMS within 24 Hrs. If you need to update both email ID and mobile number, firstly you need to update mobile number and then your email ID by following the same procedure.
