Dombivali mumbai side is very low net proble but when I go ghtakopar or mumbai side waha pe acha network rehta hi. Or internet bhi acha chalta hai; and yes sim battery bahot cansume karta or phone jaldi band ho jata hai.fly flam 7 jo phone aa raha hai wo phone pahot hit hota hai when jab ham data conection on karte hi tab or jada hit hota hai.other wise its good network and also roming free’ but 4g ka speed nahi milta hai or kabhi to achanak neteork jata hi or phone restart ksrne k baad hi neteork aata hai. But mujhe esa lagata hai aane wale time ye bahot use hone wala hi.
