Worst network, Customer care service flop. Please don't buy this service guys. Reasons as follows
1. No promised speed (I am paying for 100Mbps but getting 3 to 4 Mbps)
2. Frequent connection fluctuation, but no customer support on time
3. They could send message regarding scheduled maintenance, but taking additional one day to up and running from the mentioned time
4. Good at collecting bill without fail
