Hi all,
I was wondering if anyone has access to a LTE device (like a 4G USB dongle) and has been able to trace the communication between the SIM card and the device yet.
Does it need to be in a 4G radio area or just with the device?
Samsung GT-B3730 should be 4G.
If so, it would be great to get some traces. Feel free to patch out the IMSI, PIN number or any other private details (or simply filter those messages, if you care to).
Is there some easy way to do this, like a readymade filter? I usually replace PIN codes with 1234 or similar, but how to strip network-related bits?
there is no ready-made filter. But then, there isn't much privacy related detail apart from * reading EF.ICCID * reading EF.IMSI * writing EF.Kc / EF.KcGPRS * writing EF.LOCI (location area code) * writing the TMSI
it shouldn't be too hard to filter those messages manually when looking at the trace.
