Tata DoCoMo is the awesome ISP that I have ever used till date. I have used other ISP’s(do not want to name them) and what makes DoCoMo unique from them is various plans.
The plan they offer is affordable and do not take away your hard earned money from you. More over when you recharge online, you also get 10% extra usage which means if you go for a 10 GB Limit, you get 11GB and that too at a much unbelievable price. I have 2 USB’s with me and I use them regularly.
One of them, I got it as as gift for buying a mobile. I just had to pay for the usage and I got 10GB for just 899. The Speed is also too good and reliable and I have hardly faced any disconnections. It is certainly worth going for it. Only thing is they keep upgrading their USB models from time to time which I can understand from the business point of view, it is essential and required as technology advances but may not go well with consumers all the time since at time, they may feel that they are left behind.
