Apparently MTNL has an option called Safe Custody where you can keep your connection is sleep state for a specified period of time. You will not be charged any rent, not even modem charges and you can resume your connection after the said period. I have done just that and taken a DEN Broadband connection from Sep 1st. I got a special offer on Aug 31st where they waived off activation charges if I paid the same day. As advertised I also got a free wifi
router, its a
TP-Link TL-WR740N.
My review:
Ping and Traceroute: DEN Broadband doesn't allow you to ping or traceroute any IP or website except for their own connectivity IP. Calling them didn't help as they think they are helping discourage DDOS attacks from their users. Ofcourse if you still want to use ping, you'll have to get a static IP from them which is paid.
Static IP: Unlike MTNL, DEN doesn't provide you with a static IP, you have to buy one from them for Rs. 2000 per year
Downtime: Its been 15 days since I started using this connection and till now I've faced downtime twice. Once around 2 or 3rd september, I got back from work at 3AM and the connection didn't work. I found no issues with the connectivity but no internet working at all. It started working automatically by the time I woke up at 11 AM next day. Second time it went down yesterday for a few minutes. I could ping their server fine but internet didn't work. It started working after a few minutes. No other downtime faced other than these 2 incidents
Speed: I'm getting average 10mbps as expected with a few data bursts going even higher. The highest burst I recorded was 17mbps.
Upload: Upload speed is claimed to be 1mbps however I haven't seen it reach even 512kbps. I am going to call them for this, I just didn't till now as I kept trying to get ping unblocked for free all this time, which obviously didn't work out.
Overall I'm quite satisfied with the connection however I'll hold my final decision on going back to MTNL till October 25th. As of today, it looks pretty likely that I'll continue with DEN.
Feel free to reach out for any questions.
