Mtnl Delhi is back with night unlimited data a decade after it withdrawal of 590 NU plan.
Currently it’s valid for all the adsl triband broadband plans of Mtnl Delhi. Here is the quote from Mtnl Delhi site:
Free Broadband data download during night hours (00 Hrs to 0600 Hrs) to all Fair usage Unlimited plan (FUP) of ADSL broadband working in MTNL, Delhi on promotional offer for one month w.e.f 02.10.2018.
We are sure it would be extended indefinitely as no is using Mtnl anymore. Most local cable operators offer way better true unlimited plans than Mtnl adsl plan with no hassles of line sync issues, weather issues, old line issues etc.
