In theory MCC/MNC should be unique even for MVNOs.  But some have not =

followed that properly.  SPN is free-form, but it probably doesn't =

change all that often.  The provisioning database would have to be =

updated frequently.

If you know you will only need a subset of particular providers, it =

might be easier to develop your own provisioning db.

I don't recall that any provisioning (proprietary or otherwise) database =

used ICCID as an identifier.  Not saying it won't work, so feel free to =

investigate what is possible.
