I posted a question how can i what are the different ways to access internet in laptop/desktop/tablet. And got answer as 1) broadband 2) datacard 3) wi-fi. But I am not fully satisfied with this answer because I have heard another way of accessing internet--- doongle with SIM card slot--- the same way and at same cost we incur to access internet in mobile phone. Is it true ? If so which brands are available in market and how to use it ? Any help?
