I have used several networks. Most of the mobile operators have only big recharge offers for small internet packs. One time I heard from my friends that bsnl have several good offers and thats why I changed my mobile connection to bsnl. At first I had bad experiance with bsnl. Now I will say that bsnl is the beast because today no one in this field can compete with bsnls plans. I have recharged the pack of Rs. 395 last month. The pack is about Daily 2Gb internet and call free for 70 days. Till now I have no issues. Internet speed is superfast. I am a fan of bsnl.
