Address:

Thane, Maharashtra, 400605

Facing a problem since many months network is very poor. Speed is worst than even 2g. 4g network is behaves like 2g.
No improvement in performance since many months. Unlimited calls getting dropped after every 5min. It couldn't be finsihed as long as u want. Many times ppl facing problem o[censored]nreachable number and not receiving any single message of attempts calls. Why does the performance gone down?? Where the ucla report has gone?
