And here is the Steps:
Hi all..
If your Vodafone dongle is Software locked then
here is the guidelines to use the other service provider SIM card with your Vodafone mobile connect application (VMC).
Basically if you use other SIM cards, VMC wil say "Invalid SIM, please contact customer care"

It is little complex, but I think you can do it easily.

You have to modify the below 3 files on the below location where
you have installed VMC (Default path is C:\Program Files\Vodafone\Vodafone Mobile Broadband\Opco)
Here you will find your country name (In my case I selected "India")
basically you have to add a additional MCC MNC Code (Mobile Country & network code configuration)
for your SIM card which is non-Vodafone SIM.

You can find out your SIM Card MCC MNC code from your "Customer Support" or from the below URL
[CODE]http://en.wikipedia.org/wiki/Mobile_Network_Code[/CODE]

I have used the SIM card from the Service provider "Airtel" it is from India and the
MCCMNC config file for Airtel is missing in the folder "C:\Program Files\Vodafone\Vodafone Mobile Broadband\Opco\India"

So now you have to add my SIM cards MCCMNC configuration into VMC.

just open the below file named "Opcos.XML" for adding the "Airtel" network code details
C:\Program Files\Vodafone\Vodafone Mobile Broadband\Opco\Opcos.XML
Backup a copy of your existing file Opcos.xml & edit as per the below example (here My provider is "Airtel")
Now Delete all the content of the file & add the below 4 lines into it & edit the "CCMNC" code of
yours SIM provider & "Opco" is the provider name & "country"=your country name

[COLOR="Blue"]<?xml version="1.0" encoding="utf-8"?>
<Opcos>
    <OpcoEntry CCMNC="40492" Opco="Airtel" Country="India" Phone="9892012345" PhonePrefix="+91" TrunkPrefix="0" DisplayLocalNumber="true" />
</Opcos>[/COLOR]

Now you have to add another 2 new configuration file into VMC on the below location
C:\Program Files\Vodafone\Vodafone Mobile Broadband\Opco\India
file 1 should be your SIM card provider "MNC Code.XML" (for me it is 40492.xml) &
file 2 should be "Opco-your SIM MNC code.xml" (For me it is Opco-40492.xml)

you can see below the example of the file1 40492.xml
Here you have to edit CCMNC, OPco, Country, Phone Prefix & APN information as per the below example
Here my 'Airtel" APN is 'airtelgprs.com"
You just edit & save the file as per your SIM provider requirement.

<OPCO xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

  </BuildVersionInfo>
  <OpcoData CCMNC="40492" Opco="Airtel" Country="India" Phone="9815051914" PhonePrefix="+91" />
  <APNs DefaultAccount="Prepaid" SwitchMarketSegment="true">
    <APN Account="Prepaid" Apn="airtelgprs.com" HomeOP="" Name="Prepaid" Pass="" I="0" User="">
      <AutoVPN>false</AutoVPN>
      <ConnectionBehaviour>Manual</ConnectionBehaviour>
      <Security>None</Security>
      <Network>AllNetworks</Network>
    </APN>
    <APN Account="Prepaid" Apn="airtelgprs.com" HomeOP="" Name="Prepaid" Pass="" I="0" User="">

      <ConnectionBehaviour>Manual</ConnectionBehaviour>
      <Security>None</Security>
      <Network>AllNetworks</Network>
    </APN>
  </APNs>
</OPCO>[/COLOR]

Now the another file 2 which is named "Opco-40492.xml" see the below examples
here you have to edit only URL address (in my case it is [CODE]http://www.airtel.in[/CODE])
and save the file.

[COLOR="blue"]<?xml version="1.0" encoding="utf-8"?>
<OPCO xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

</OPCO>[/COLOR]

Now you can start VMC with other service provider SIM card and connect to the internet.

You can find the attached file for your reference which I have made for Provider Airtel India. You can download & edit the files as per your requirements.
