Totally waste of your money if you want to use tata docomo as your service providor. I used it for 3 months and faced many issues like networks problem every time, internet is very slow even you cannot use facebook lite application and the customer care never picks up call.
I ported my tata docomo sim( 8981203840) to Airtel due to these problems. But I liked one thing that that I got the best call rates at low pricsn but after jio no call rates required.
I would not suggest you to go for this service provider.
Thank you
