I am using gtpl connection from past 2 years and I have a pretty decent experience.
My plan: currently I am using 1mbps unlimited plan for 6 month paying?4800 which I think is very expensive compared to other ISP.
Except price the service is good I havent face any major issues regarding to the Internet connection.
Sometimes the connections are offline for some hours( eg for 4-7 hours) on every month but the connection again this online, so its not a major issues
If any how the company managed to lower it price turn I feel it will be the best isp.
