Hexacom of Shyam Telelink/TCIL(Govt)/TIL-Canada Grp is providing Mobile Services in name of OASIS. Done a great job in Rajasthan. Drove out Essar, its market share soaring at 80%. Good strategies of reducing the charges. Good Customer care. However, the network is not spreading very fast. 100% of highways not yet covered, even though major towns are almost covered barring few Dist HQs. If some Hexacom guy is reading this, may like to take the suggestion from other mobile operators to have Roaming on cash cards. Its such a convenient thing to have when you are out of state. Overall connectivity is quite good. Network is gone very seldom. However, more combinations may be offered to customers to choose from.
