BSNL Offers Validity Extension Using Combo & STV Prepaid Plans BSNL has implemented two changes to its account validity extension scheme. For the unaware, BSNL provides two grace periods before suspending the mobile number of a user. For the BSNL users who are already in Grace Period-I or Grace Period-II, the telco allows them to recharge STVs/Combo vouchers of Rs 75 and above to make their connection active under the base plan with a validity of the recharged STV/Combo vouchers for all plans. In the second scenario, customers who are currently active under corporate/circle specific plans, they can recharge with Plan voucher after every “plan/recharge validity” period or any applicable recharge to avail the benefits under this tariff plan. In case of recharge with applicable STV/Combo voucher, the validity of tariffs plan will be extended corresponding to the validity of that STV/Combo voucher. In case, if the customer fails to recharge with plan voucher or any applicable recharge at the end of the validity period, the telco has the right to provide the plan benefits under Grace Period-I and Grace Period-II. After the second Grace Period, the services of users will be suspended. Do make a note that the Plan validity service is not available on self-care subscriptions. The Grace Period-I is valid for seven days after the incoming facility will be removed, whereas the Grace Period-II is valid for 165 days after which a user’s account will get terminated.
