I would really recommend this sim to all of you. I am just fan of bsnl and its data packs and I want you to be part of bsnl by joining this network.even this is not a private limited still I found best among all other.all the data packs are cheap and provide good offer. for instance I have recharged my bsnl sim with data pack of rupees 444 which gives 4gb per day and 90 days valid. where as in other sim like jio its only 1 or 2gb per day.so bsnl is cost-effective. they even provide good customer service.even the call rates are so cheap it depends on which validity pack you have choosen. only the problem is we have to recharge with validity pack where in all other sim comes with 10 or more years of validity else bsnl is favorite of all other networks. thank you
