In the Era of free Unlimited 4G, I subscribed for Reliance Broadband due to my business need. But After Getting installation done(It took 10 days in Chennai) I started facing problems from the first day.The main issues were slow speed(100-200 kbps against my Plan-512 kbps).
The situation got worst when it stopped working for hours. I had to call the local boy who installed to make things work frequently, but the situation remained the same. However, I had subscribed for just 3 months, I never renew the plan again. Try going for 4G data packs or other local ISP rather then this reliance broadband that would be my closing advice.
