Its possible to use an 2G Card outside of the normal Freq?
Maybe I could get an Licence for an 2G Cell but all Freq are blocked by the Network Operators. So maybe I could get an Freq next to an 2G, 3g, 4G Band.
So its possible to chance the freq?
Thanks
Unless it is by design i.e. hardware and firmware changes to make the unit operate outside the band then no. You are effectively asking for a core change to the basic functionality of the unit against the specs it has been designed to. Yuo cannot send a command and it magically operate on a different frequency.

ffu… 
How does the people do it who play with GSM Boxes?
What do you mean ‘GSM boxes’?

GSM Cell
So you are referring to the initiatives like Open BTS? If so they have access to the signalling firmware plus they use generic hardware capable of operating on a wide range of frequencies which modules do not as they are bound to use specific hardware produced by the chipset providers which are designed to the 3GPP specs.

yes i mean open bts.
