i m using vodafone card n activated bb service

but when i try to 3g option in not working ....

only workin 2g n EDGE

n when selected 3g its showing emergency call


so whats the solution............

First you need to determin if your provider offers 3G service in the location that you are trying to access it. Give them a call!

It is recommended that you set the phone to automaticly switch to the fastest available network. To do this go to OPTIONS > NETWORKS AND CONNECTIONS > MOBILE NETWORK and then ensure that Network Mode is set to '3G & 2G' then press the return arrow key to save the changes.

Hope this helps.

Also make sure the device your using is capable of 3G in the correct Band / Frequency range. Not all networks use the same band across the world.
