If you are looking for a recharge plan that offers longer validity at a lower cost, then only BSNL can offer this facility, not Jio, Airtel or VI. Because all private companies have increased the price of their plans. In such a situation, if you use two SIMs and want a better plan to keep the other SIM active, then you can recharge BSNL's Rs 107 prepaid plan.
BSNL Rs 107 plan
Firstly, BSNL's Rs 107 plan comes with 35 days validity. Which is really unbelievable now. Because if you want to recharge the 28 days plan of Jio, Airtel, VI, you have to spend around 200 rupees.
BSNL offers data benefits in Rs 107 plan. 3GB data is available here with 200 minutes of voice calling. Note that no SMS facility is provided with this BSNL plan.
Jio Rs 209 plan
The validity of Jio's Rs 209 plan is 22 days. This plan offers 1 GB data per day. That means a total of 22 GB data will be available. Unlimited calling facility is also provided here.
Airtel Rs 199 plan
Airtel users now need to recharge their SIM card by Rs. 199 to keep it active. The validity of this plan is 28 days. Users will get 2 GB data, unlimited voice calling and 100 SMS per day.
