Fwd: Cellphone can't detect sim card
by Tali Budur 24 Jul '13

24 Jul '13

Hi! I have built 2 units of simtrace hardware recently. All the components came from digikey, I used the bom list from git. The PCBs are electrically tested. When I connected it to the pc, simtrace application can communicate with the device and I can debug it via the FTDI connection. The problem is, when I connect it to a cellphone, cellphone can not detect a sim card. Simtrace can detect vcc on, vcc off and rst signals from the cellphone however, cellphone can not detect the sim card. I used several different cell phones and sim cards. I also checked the connection between the cellhpone and simtrace. Couldn't find a problem. May I kindly request your help to solve the problem? Thanks,

SIM tracer for Saleae Logic
by Tom Schouten 10 Jul '13

10 Jul '13

Hi List, This might be of interest to folks here. A couple of days ago I found out the Saleae Logichas an SDK that allows you to live stream raw sample data straight into a C++ application. Quite neat, as it can go to fairly high sample rates. Here is a proof of concept version of a live APDU protocol sniffer using the SL: https://github.com/zwizwa/sl-apdu Essentially it's just a UART state machine with some hardcoded ATR parsing (for the specific SIM card I have) which calls into apdu_split from git://git.osmocom.org/simtrace.git after the ATR handshake. I had a look at the ISO7816 parser in the SIMtrace firmware, but it's fairly tied to the hardware. With some refactoring it's probably easy to reuse. ( The sl-apdu repo has a first attempt to a dirty stub approach to run the original AT91 code. Probably not be the way to go.. ) Cheers Tom

Hi guys, I'm thinking of making an application on top of simtrace, but my focus would be on Windows users. I'd like to know if the application runs ok on Windows systems. -- Atenciosamente, Hugo Frederico Soares

Incomplete trace (due to high-speed SIM?)
by Arthur Léna 22 May '13

22 May '13

Hello. I am trying to trace the communication between a Free Mobile (french operator) and an iPhone 4S. I am using the simtrace tool and libosmocore library taken from the Ubuntu PPA repository given in the user manual (ppa:holger+lp/osmocom). I tried booting the iPhone using 2 different SIMs (this one from Free Mobile and another one) and the trace seems very short using the Free Mobile in comparison to the other one. By parsing the ATRs of both SIMs, I found out that the communication is done at 312500 bits/s with the Free Mobile SIM and only 78125 bits/s (for a clock running at 5MHz). Could this explain the loss of entire ADPUs by the tracer? If yes, is there a way to remedy to this problem (firmware update for example). Best regards, Arthur Léna FYI: the ATRS of both SIM cards Free Mobile: 3B 9E 96 80 1F C7 80 31 E0 73 FE 21 1B 66 D0 01 77 97 0D 00 EC TA(1) = 0x96 Fi=512, Di=32, 16 cycles/ETU (250000 bits/s at 4.00 MHz, 312500 bits/s for fMax=5 MHz) A1: 3B 3F 94 00 80 69 AF 03 0F 07 A4 00 00 06 0E 83 3E 9F 16 TA(1) = 0x94 Fi=512, Di=8, 64 cycles/ETU (62500 bits/s at 4.00 MHz, 78125 bits/s for fMax=5 MHz)

Feedback on micro-SIM (3ff) FPC adapter cables
by Harald Welte 04 May '13

04 May '13

Hi all, as we are getting more and more inquiries for micro-SIM (3FF) FPC adapters for the SIMtrace, I would like to inquire on this list before we go into productin. My main inquiry is about the orientation. As you know, the current mini-SIM adapters come in four flavors, one for each of the possible orientations. Hoewever, as there are still few phones with 3FF SIM card support, I was hoping we don't need to produce 3FF FPC adapter cables for all four orientations. Does anyone on this list know which orientations exist and which don't? This would help us to proceed quickly with manufacturing the adapters, without spending extensive amounts of time researching on required orientations.

Create File APDU for GRCard SIM
by Matt S 23 Apr '13

23 Apr '13

Hello, I'm struggling to get the 'CREATE FILE' APDU to work on a GRCard SIM. I'm using the cyberflex-shell in interactive mode to send apdu's. Even though I verify ADM pin 5, and follow the format on the wiki ( http://openbsc.osmocom.org/trac/wiki/GrcardSIM), I still get the reponse 0x9804 from the cards. I must be missing a step? Below is my failed session with a SIM, trying to create FID 0xabcd under 3f00/7f20. Any guidance is greatly appreciated. ATR: 3b 99 18 00 11 88 22 33 44 55 66 77 60 (;....."3DUfw`) (ISO 7816-4) > raw a0 20 00 05 08 44 44 44 44 44 44 44 44 -------------------------------------------------------------------------------- Beginning transaction 0 >> 0000: a0 20 00 05 08 44 44 44 44 44 44 44 44 . ...DDDDDDDD << 0000: 90 00 ..

SIM detection failing on Samsung Galaxy S III
by Rupert Lloyd 17 Mar '13

17 Mar '13

We received a simtrace board a few weeks ago and have been able to successfully use it on a Google NexusOne and iPhone 4s (using a dual SIM adapter). When we have tried it on two different Samsung Galaxy S III devices both were unable to detect the sim card. We verified that we could read the same sim cards when placed in other devices. Has anyone else had success or failures on using recent 3G/4G devices? Are there more tests I could run to isolate the cause? Rupert
