RSE spot checking help

We are do RSE spot testing and need to be able to turn on all the different carrier bands and power them up. We are using the Q24PL003 module.

We don’t have a test network to activate calls on, all we can do is power-up the different bands (850/1900, 900/1800).

The question is, how do we do that. I have not found any AT commands that will power-up different bands. I know that calls will not be possible in the bands that are not supported by our wireless provider, but we should be able to still attempt to make those calls.

Any information is much, much appreciated!
