With the non-LTE devices (Gobi 1K - 3K etc), they were already
provisioned enough to talk to the network because they were CDMA-only
and didn't need SIM cards.  That initial information is all stored in
the Gobi firmware images for each provider I believe.  But they were
un-activated, which is what that API was for.  We made sure it was
generic enough to do non-Gobi activation too, but that never got
implemented.

CDMA/LTE devices now go through the same procedure as 3GPP devices do,
since the SIM must be provisioned/activated too.  This means the device
originally may not be optimally provisioned for the 3G CDMA network
(lacking correct PRL or ERI or NVRAM variables) but that happens during
the 3GPP provisioning steps, I would assume.

(although, since CDMA/LTE providers here all use different LTE
frequencies, you still have to buy devices specific to that provider,
and thus it may well be minimally provisioned for 3G at the factory.
Not sure about that though...)
