    2G and 3G

      Dear All,

      I have read few articales on the internet about the difference between 2G and 3G networks. I have read the advantages of 3g over 2g but I could not find answers of the following question :
      1. What changes we will need to do on network level and on sim level if upgrate from 2g to 3g ?
      2. Will 2g sim cards work under 3g network ?
