How to change your airtel corporate mobile plan

I have a corporate airtel postpaid mobile connection and the plan was not very cost effective for my usage pattern. However, trying to change the plan by giving a call to their 121 call centre was of no use as the support staff seemed to lack the access to change corporate plans (in fact they didn’t even seem to have proper visibility to my eligible corporate plans). In fact, the phone support told me to visit an airtel relationship centre for a plan change. The website wasn’t of much help either as corporate plans can’t be switched online, and the airtel website is seriously lacking in any kind of details on postpaid corporate plans.

Email was a different story, and their response time is pretty phenomenal with replies coming in within 4-5 hours even on weekends and nights. And this was the route that ultimately got me success. So here go the steps:

  1. Log on to the airtel account management site (if you know your registered email ID, jump to step 3).
  2. Check your email address under the personal information section and update if not active (you can also sign up for an ebill under the bills section).
  3. Send a mail to 121@in.airtel.com from your registered email address with the name of the plan you want to switch to, and your mobile number as the subject. In case you are not sure of the plans you can switch to, drop them an email first asking for the available plans. Word of advice: keep your message short, simple and to the point.
  4. You should receive a confirmation mail and voila, you’re done!

If you are curious on the plan I got, it was the Alive Net CUG 375 Combo Plan with 600 minutes of local & STD talktime and 1 GB of 3G data as part of the package. There are similar combo plans available that are tuned for local usage if you are interested, and they are quite economical when compared to your usual subscription of a call plan with a separate data plan.

Modem settings for MTNL broadband

Mahanagar Telephone Nigam Limited

I finally got an MTNL broadband connection at home (Mumbai). Since I decided to get my own TP-LINK modem+wi-fi router (a good value for money model that I plan to review after a couple of months of use), I had to do the modem settings on my own. The settings for some models are available on the MTNL site, but it was missing for my particular model. The modem’s default PPPoE dialer settings did not seem to work, so I decided to check out one of the MTNL documents, and here’s the configuration that I found:

Username: <phonenumber> OR <phonenumber>@a E.g. 12345678 OR 12345678@a

Password: <CA number> (you can find this from your bill, or by calling 1500 from the landline) E.g. 4567890123

VPI: 0

VCI: 32

(The VPI & VCI settings chosen by my modem were different due to which it failed to connect & I had to change them manually to the above settings)

Connection Type: PPPoE LLC

MTU: 1400 bytes (another setting that had a different default on my modem)

MRU: 1492 bytes

Default route: Enabled

NAT: Enabled

Firewall: Disabled

You can also set the DNS servers manually to point to OpenDNS (208.67.222.222/208.67.220.220) or Google’s DNS servers (8.8.8.8/8.8.4.4) which should prevent ISP level DNS blocking of sites, and most likely provide better lookup speeds.

Below is the D-Link modem settings from the MTNL document from where I have picked the settings.

As for the wi-fi settings, you can stick to the defaults – just don’t forget to secure your network using a passkey to keep away free riders.
