There was some discussion if we could hack our way around this using
some test script or something.

I'm afraid it is not possible to send SAT command to SIM from ofono
without overall working SAT support in phone. I'm not familiar with
roaming enabling feature described but I've been doing lot ot SAT.  I
suspect that when it works it works most likely like this:

- At startup modem tells to SIM card that it supports set up menu by sending terminal profile to card. 
- Card sends set up menu SAT command to the phone which triggers the drawing of the operator menu to UI.
- User selects request that enables the roaming. Based on selection phone triggers menu selection SAT command to card. 

Now, I can only guess what card does at this point: Normally I would say
that most likely card orders the phone to send sms to the operator using
send sms SAT command. (Send USSD would not work, because it is
apparently aimed to work in a roaming network.) Then the operator would
send update request to the card via SMS PP Data Download or some other
update mechanism which would enable feature user is requesting. However,
since the network listing shows that phone is forbidden from the roaming
network phone should not be able to send message. I think only thing
that can happen is that menu selection directly updates some value in
the card.

I don't know if the Krillin is giving the terminal profile to the card.
(Mako does, I've seen the SAT messages in traces). If the phone does not
give the terminal profile to the card, there is nothing we can do. Card
won't sent the setup menu command and it will ignore menu selection
command we would send. At the moment ubuntu-touch ofono does not support
the forwarding the command to client but if it would, we could capture
the set up menu request with test-stk-menu test script and send menu
selection request from there.

Title:
  Sim toolkit is not available on UT

Status in “ofono” package in Ubuntu:
  Triaged
Status in “unity8” package in Ubuntu:
  Triaged

Bug description:
  E.g. of SIm toolkit is http://support.vodafone.com.au/articles/FAQ
  /SIM-Toolkit

  While a lot of those addons are completely crap and useless, the SIm
  toolkit is sometimes used by some phone provider to set your sim card
  to roaming mode when you are abroad which makes it a must have.

  For the moment i need to borrow a second phone put my sim card in it,
  go to the Sim-toolkit, enable my sim card for roaming and put the sim
  card back in my UT to get my phone working while i am abroad. I need
  to do the same when i go back home.
