* the device is never roaming. Any operator-defined IDs (greater than 2)
* may or may not be roaming, but that's operator-defined and we don't
* know anything about them.
*
* Indicator ID:
* 0 appears to be "not roaming", contrary to standard ERI values
* >= 1 appears to be the actual ERI value, which may or may not be
* roaming depending on the operator's custom ERI list
*
* Icon ID:
* 0 = roaming indicator on
* 1 = roaming indicator off
* 2 = roaming indicator flash
*
* Icon Mode:
* 0 = normal
* 1 = flash (only used with Icon ID >= 2)
*
* Roaming example:
* Roam: 160
* Indicator ID: 160
* Icon ID: 3
* Icon Mode: 0
* Call Prompt: 1
*
* Home example:
* Roam: 0
* Indicator ID: 0
* Icon ID: 1
* Icon Mode: 0
* Call Prompt: 1
