Let us know briefly about what is 2g and 3g and what are the secrets inside:-

          We are very familier with the below words

  1. GPRS
  2. EDGE
  3. UMTS
  4. WCDMA
  5. 2G, 2.5G, 3G, 3.5G
             But interesting thing is that many of us dont know the difference of them. We will go to the market and we will purchase a 3g mobile but many of them dont know that 3g mobile with out 3.5G technology only supports data speed upto 368kbps. So, it is very important for us to know the difference between the above basic terms before purchasing a mobile.


2G
GPRS
2.5G
EDGE
3G
UMTS
3.5G
WCDMS/HSDPA
Dowload Speed   up to
144kbps
238kbps

             For video calling 3G network with 368 kbps is enough. If u want to go for internet browsing at high speed 3.5g is needed.

            Many of the network providers providing 2g plan and 2g speed with 3g signal, If u need internet only for browsing u can go for 2g plan with 3g signal. eventhough it is 144 kbps it is very good for browsing when u go with 3g signal.
