Although BIP support (stands for Bearer independent protocol) used mostly to access remote resources from SIM card using packet data interfaces such as GPRS was implemented quite a while ago in our CellSIM operating system we have never had a chance to test it in field. All previous tests were only done in a normal card reader.
Today we did real tests using BIP managing (U)SIM card remotely: application download and installation, file management etc. Speed compared to SMS based transport was really a fun.
This is quite sad that not so many handsets, especially mainstream like Android or iOS support such a feature. Let's hope that support for BIP will be integrated into RIL library of Android in the nearest future.
