Dlink Router 3G Configuration for MTNL BSNL Airtel


In one of my previous post I have dealt generic 3G configuration of D’link Modem/Router (2750U) for any SIM. But lot of people are mailing me to write specific SIM configuration. That’s is why this little repetitive post is being written.

I will not deal with all the basic configuration here, for that look at d’link 3G configuration post.

Assuming that you have read the suggested post and ready to tweak it for your SIM. If you will notice that there are just few things which differs from sim to sim. In previous post’s step 7 you need to make sim specific changes.

For MTNL Users:

Account : mtnl

Password: mtnl123

Dial_Number: *99# (MTNL says that you can leave it blank too)

Net-Type: TD-SCDMA

APN: mtnl.net (Both for Delhi/Mumbai)

For BSNL Users:

Account: bsnl

Password: [blank]

Dial Number: *99# or *99***1#

Net-Type: TD-SCDMA

APN: bsnlnet

NOTE: This BSNL APN is valid for these states: Haryana, Punjab, UP(East), UP(West), Himachal Pradesh, Rajasthan, Jammu & Kashmir, Jharkhand, Bihar, Kolkata, West Bengal, Orissa, Assam, North East, Adman Nicobar, Maharashtra, Gujrat, Madhya Pradesh, Chattishgarh, Karnatka, Andhra Pradesh, Chennai, Tamil Nadu, Kerala.

For Airtel Users:

Operator : airtel

Password: [blank]

Dial Number: *99***1#

Net-Type: TD-SCDMA

APN: airtelgprs.com

NOTE: If you feel that these settings are not working then make a call to airtel call center and ask them APN for 3G. Rest of the settings will remain same, although you can cross-check them too.

The point here is to note is that almost all major mobile carriers are now using a common APN for all the states. So, if you have free data roaming then you don’t need to change settings from state to state. If network provider is providing 3G in a state then these settings can be considered as default settings.

Configure Dongle for Any SIM Card – Generic Dongle Configuration Method

If you have got a sim and a dongle but don’t know how to configure your dongle to accept your SIM card of any Service Provider (MTNL, Airtel, Vodfone, BSNL, Aircel or any other company). This is a generic guide to help you in configuring your dongle. It doesn’t matter which dongle you have, if it allows you to configure some settings then you can configure it easily (Unlocked Dongle). But if it’s locked by service provider then I am afraid that there is no way except using your service provider’s SIM.

How to Configure Dongle for Any SIM Card

There are some dongles in the market that requires no configuration. They have such settings already installed for almost every SIM available. For Example a d-link dongle has all such settings pre installed.


What If Your SIM settings are not present?

It’s quite possible that your sim settings are not available in the SIM or your dongle doesn’t have pre-installed SIM settings then how to configure it.

To configure Any Dongle there are actually 3-4 things required:

1) APN (Access Point Name)

2) UserName

3) Password

4) Authentication Type

5) Dialing Number

It’s not necessary that all SIM and All Dongles requires all these settings. Some might not be present. For Example If you are using MTNL then there is no need to give dialing number. Similarly different sim requires different options.

From Where Can I get These Settings?

Make a call to the call center or the SIM and ask them to provide 4G /3G / 2G settings (whatever you case is). They will give you above discussed settings according to their network.

Simply insert these settings into your dongle and you are done.

Example in d-link dongle:


Fill out all these settings according to your network (given by call center) and click save. Then these settings will gets saved and you will be able it. Now simply click connect and it’s done.

What If My Dongle is Locked?

There are certain dongles that are locked and doesn’t allow you to enter such custom settings. Although there are softwares available to unlock the dongle but I can’t recommend any at this point of time. They make changes in the default software of dongle and if for some reason it doesn’t work then your dongle will be of no use.

If you are still keen to use such unlocking software then have a look here and make sure that your device is listed there before performing unlock.
