Why most custom 4.3 Android Roms are dropping STK (Sim Toolkit) functions?
I have been looking for weeks and weeks for a solution on how to have my 4.3 SlimBean Galaxy I9100G work with the dual sim adapter I bought from MagicSim.
I cannot use that adapter simply because STK is not taken into account in most of the custom 4.3 Roms I have flashed, in the hope I could use the STK functions in one of them.
For those who wonder why STK is important to African and Asian markets, and even to some European markets, I would point to this brilliant blog, titled "Android's Achille's Heel: The Sim Toolkit": http://j.mp/19GUNii

Now if you live in the States, you might not even know what the STK is, so a bit of explaining is in order. Put simply, the STK allows carriers to load a simple set of menus and 'applications' on your SIM card. Again, on your fancy iPhone, you may question the need or purpose for such a thing, but that's because you are still years behind and using a credit card. Here, where credit cards are virtually unknown, the present and future of payments is Mobile Money, which is almost always delivered via.. you guessed it, the STK.
I have sent tens and tens of emails to Rom cookers, to teams such as Slimroms... in vain.
It is really frustrating not to be able to use such a wonderful thing as a dual sim adapter because your rom does not support stk.
The solution would be to downgrade to a stock Rom for my I9100G phone... It's not really a solution.
The solution should really come from developers, who should have in mind the needs of users from around the world...
I hope this post will help advance the cause of STK among Rom developers...
