Field tests of remote applications and file management on the SIM via BIP

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.
