I ned a fast connectivity and heavy data limit for my research work. I am using BB-800-2M plan from MTNL, Mumbai. I am highly satisfied with the speed (200-300 kbps average in normal hour) and 70GB FUP. The speed increases at night. I am expecting this good service since Jan 2017. Earlier, I faced many problems and earlier managers did not attend it properly. However, the service is good after Jan 2017.
