Tata docomo it is still on 3g network and speed is so poor just like bsnl it does not work properly no proper plans like bsnl. Tata docomo says it has fastest 3g network and it does not have even speed like its competitors idea and vodafone. Network is also not great India is just going to touch the 5g mark and it is still on 3g network and I think it will close in some days.
I don’t have any idea that tata docomo will also get 4g bands in India.Many of my friends I have already ported there sims to other network like airtel, vodafone, idea and jio .
Please stay away from this sim card company no proper network no proper plans.
