Didn’t your mobile operator get 3G license for your circle? Well, you certainly have something you can do about it. Take advantage of the Mobile Number Portability (MNP) that is going to come live from 1 November 2010. Say you are on Vodafone network that failed to get a 3G spectrum in Andhra Pradesh. Simply take advantage of MNP and shift to Airtel (or Aircel or Tata Teleservices). You’ll have the same old Vodafone number but will be on the Airtel 3G network.
What if you absolutely love your mobile network and wouldn’t change for anything?
Well, change your circle then 
Move to a State where it has a 3G License.
Or if you have patience, you can wait for ‘something’ to happen. That something can be that a network which secured 3G license in a state ‘may’ share its 3G Spectrum with other network that failed to secure a license. This ‘may’ happen if the network that secured the license fails to get a ‘profitable’ response from its subscribers even after a prolonged period.
Also, there will be Spectrum allocations even in the future when your Operator may attempt to get a license. When that will happen is any body’s guess, though.
Keep in mind that some SIM cards, lower than 32K memory, may not get the best out of 3G network even if your move to a 3G network using MNP. So it is advised that you upgrade your SIM card to 64K first, being in your old network, and then use MNP to move to a 3G Network.
