I have been using Tata Docomo internet from long time and I have encountered that internet speed on Tata Docomo network is the lowest in all over indian network.
And the internet pack cost is as some as others which make me think that it has no value for money, the internet is so slow that some time I feel difficult to receive my whatsapp msgs. I request Tata Docomo to check on their speed of internet to compete with other network speed in market.
