So, make use of TRAI mandated "SAFE custody" scheme; if you are not going to use the number for a prolonged period. This is a good action by TRAI as people like to retain their old numbers when due to job restrictions they are posted out to other circles where they may have to pay roaming charges or they move abroad.
Charges for "Safe Custody Scheme"
- The charge can not be more than Rs. 150 for three months to retain the inactive number.
- Telecom operators will not charge monthly rental during the period when customers opt for safe custody scheme.
TRAI has barred telecom operators from deactivating mobile number of those post-paid customers who have paid advance rent for certain period.
