How to access internet so cheap?

In one of my previous post, I have written something about a cost-effective method to access internet via GPRS. Many people use it in their own mobiles and rarely in their computers. To use internet through GPRS in computers with MS Windows platform, one has to install third party programme to access the GPRS Modem inside your mobile phone. (For Nokia phone, users has to install Nokia PC Suit.) But in GNU/Linux systems, all you need to install a tiny dialler programme named "wvdial". In this post I'm explaining how to access internet with TATA.DOCOMO.GPRS PREPAID DATA.PLAN in SAMSUNG C-5212 Model phone.

Required items
  1. Tata Docomo is the cheapest GPRS pack
  2. Samsung C-5212 model is the cheapest phone having GPRS MultiSClass 10
  3. Note: Samsung C-5212 supports upto GPRS MultiSClass 10. Nokia E Series phones has GPRS MultiSClass 32. These phones has capability to upload and download with higher speeds. Eg. for voice chatting you need to have a GPRS MultiSClass32 phone. Otherwise the other party cannot hear clearly. Other Nokia phones with GPRS MultiSClass 32 are : Nokia 2700 | Nokia X2 | Nokia C2 | Nokia X2 | Nokia C3 | Nokia C5 | Nokia X3 | Nokia X5 | Nokia C6 | Nokia E72 | Nokia 6303i | Nokia E61i | Nokia E90 | Nokia E65 | Nokia E51 etc.
  4. Computer having GNU/Linux OS
  5. the package named "wvdial" must be installed
  6. Notes: To install wvdial, just go to the terminal and give the following command sudo apt-get install wvdial
  7. The phone must have the usb cable. Connect the phone with computer with USB Cable.

Check which SIM is default
SIM Cards ManagementSettings > SIM Cards Management. Which SIM do you want to use as GPRS Mode, make it default. Because wvdial direcly seek the default SIM to find GPRS modem.
Browser profiles6. Application settings > 5. Browser > 9. Browser profiles. You can see lots of profiles are listed in there. Select a profile
Browser profiles in detailClick on the active profile you set for GPRS modem. In my case it is TATA DOCOMO INTERNET. The following sub sections are there
1. Set nameTATA DOCOMO INTERNET
2. HOME urlhttp://internet.tatadocomo.com
3. BearerGPRS Only
4. Proxyoff
5. GPRS SettingsDNS1: 0.0.0.0
DNS2: 0.0.0.0
Access name: TATA.DOCOCMO.INTERNET
User id: empty
password: empty

Why I explained all the details about the browser profile, is for a clear understanding on how it works. Generally you need not to care much about it. All the configurations will be done automatically when you receive the configuration sms from your mobile service provider.

Follow the following steps
  1. Execute the code in your phone *2767*927#
  2. Please wait during the lsave wap reset E2P wap reset This will reset all the browser profiles from your phone.
