I have been using this Dolphin network since 2013 , from then to now there has been not a single change in network facility & Service also. I was facing many problems when I used that Dolphin services, But the major problem was the network most of the time that was gone completely out of my network a normal area like New Delhi or Delhi NCR area. I’m talking about their, services their services still not good. If I compared to the other network like Airtel or Reliance jio on maybe Vodafone, those service provider are offering to their customers like roaming free across all India facility, reduce in date price offering best cheap rate sms package free movie downloading song downloading & extra others cool offer. I heard that some of the network operator open new Mobile Bank app facility like Airtel Bank, shopping apps bill payment app & other extra. So here I wanna try to say that this network not attract customer joined them, they have no advertisement, all I can say that this network is boring young generation.
