oFono is not designed to handle combined usage APNs.  If the APN for MMS 
and Internet is the same, we would simply 'double-activate' the same APN 
using multiple contexts. e.g. you would have an Internet context and an 
MMS context with the same APN.  This of course requires your underlying 
modem driver to be able to use multiple contexts simultaneously (e.g. 
multiple gprs_context atoms present.)

If you want to go through the trouble of adding hybrid behavior, then 
patches are welcome.

oFono only sets up a route and runs the equivalent of ifconfig.  It 
doesn't do any proxying.  This logic is there because ConnMan explicitly 
ignores contexts of type=mms.  So someone must take care of bringing up 
the interface, assigning IP, etc.

You might also want to check out the mmsd project since that already 
works with oFono.

If you have usecases in mind for some of these properties, feel free to 
suggest extensions to the oFono API.

As mentioned above, you'd simply create multiple contexts with the same 
APN and different types if you wanted to accomplish this easily.
