Both Sikka and Tachyon have the cheapest plans in Lucknow. Both these ISPs were not present in Indiranagar a year back and must have come after ACT launch in March. Of late I have heard both of them have improved their infrastructure and customer support has been good. It will be not good for them in this competitive atmosphere with 4-5 ISPs in every locality to lose customers due to bad service. Tachyon has 10,000 customers right now which is a good achievement for a local ISP in a tier II city. I believe Sikka will be having more as they have been present in Lucknow for the past 20 years. They have other businesses also and all LMRC wifis are managed by them.
As for ACT, despite the poor reviews everywhere, I went for them on March 12, when it itself had launched on March 2. Till now, the experience has been very good. I was sick and tired of Airtel DSL with horribly low upload speeds and download at 12 mbps, still I am keeping it as backup. I was talking to one ACT executive 2-3 days back and he told me that ACT has now 2000 customers in Lucknow within a short span of 6 months. There was a spree of new connections applied after the days when Jio Fiber had announced its plans on September 5. I just hope they can sustain their good performance with new customers adding up as I have seen in many other cities with other ISPs and ACT too when it becomes difficult for them to manage when number of connections becomes too high.
The executive also told me that it is likely that YOU Broadband will launch in Lucknow within this year.
