OsmoDevCall on Oct 19, 2022: SIMtrace2 Tutorial
by Harald Welte 18 Oct '22

18 Oct '22

Dear Osmocom community, after a rather extended 2022 summer break, we're happy to announce the next incarnation of OsmoDevCall. Based on the recent polls, the timing has shifted to *every 3rd wednesday of the month*! when: October 19, 2022 at 20:00 CEST where: https://meeting5.franken.de/b/har-xbc-bsx-wvs In this edition, I will be presenting a SIMtrace2 tutorial, showing SIM card protocol tracing, decoding with the new pySim-trace as well as the card emulation firmware. This meeting will have the following schedule: 20:00 meet + greet 20:10 presentation as outlined above 21:00 unstructured supplementary social event [*] Attendance is free of charge and open to anyone with an interest in Osmocom or open source cellular technologies. More information about OsmoDevCall, including the schedule for further upcoming events can be found at https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCall Looking forward to meeting you soon! Best regards, Harald [*] this is how we started to call the "unstructured" part of osmocom developer conferences in the past, basically where anyone can talk about anything, no formal schedule or structure. -- - Harald Welte <laforge(a)osmocom.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

RFC: OsmoDevCall restart: Your input required
by Harald Welte 16 Oct '22

16 Oct '22

Dear Osmocom community, your input is required in order to tune the re-launch of the OsmoDevCall talk series. One of the complaints before the suspension in Summer this year was that the "Friday night 8pm CEST" timeslot was not exactly ideal for several people. Finding a common denominator might be difficult, given that Osmocom is a dayjob for some, a hobby for most, and we're of course not all in the same time zone or even continent. So let's try to run a couple of polls to figure out: * What is the best day of the week for OsmoDevCall? https://bitpoll.de/poll/CEQnaQKEvO/ * What is the best time of day for OsmoDevCall? https://bitpoll.de/poll/59dgmzOocT/ * What is the best frequency of OsmoDevCall https://bitpoll.de/poll/8jyuRJB6Hb/ The polls are open until October 21st, 2021. I would appreciate a high turn-out so we have a good representation across our community to make an educated decision about the schedule of futur events. Can't wait to re-start OsmoDevCall!

SIMtrace v2 and phones that put out 5V toward the SIM
by Mychaela Falconia 14 Oct '22

14 Oct '22

Hello SIMtrace community, I just bought a SIMtrace v2 hw kit, and I am looking to use it for the purpose of troubleshooting ancient phones. I've been working with Calypso phones mostly, but now I am traveling farther back in time in the history of GSM, playing with phones from 1990s. I bring these phones up on my own GSM network run with a sysmoBTS plus Osmocom CNI sw stack, and I use programmable SIMs of which I bought a semi-custom batch from China a year and a half ago, semi-custom batch meaning my own artwork on the plastic and my choice of 2FF-only cut, but the actual module is unmodified off-the-shelf, the only thing I could get as a low-dollar customer. These SIMs (I named my version FCSIM1) appear to be identical to the model known in the Osmocom community as GrcardSIM2, once sold as sysmoSIM-GR2. Here is the issue: my SIMs work just fine in Ericsson I888, Nokia 5190 and Nokia 6190 - all 1990s phones - bringing these ancient phone onto my Osmocom-based GSM network quite happily. But I am interacting with another member of the vintage phone community (r/vintagemobilephones on Reddit) who has a few working Nokia 2190s - a phone model from 1995, one of the first PCS1900 band phones ever - and he tells me that this super-ancient model is very finicky in terms of which SIMs it accepts. There are several T-Mobile MVNOs who issue SIMs that still have the classic GSM 11.11 SIM application present, and they work fine in most ancient phones, including Nokia 5190 and 6190, but they don't work in 2190 - my contact tells me that he found only one MVNO (Lycamobile) whose SIMs do work in the 2190. Intrigued, I sent him a few of my FCSIM1 cards, he tested one in a 2190, and he tells me the ancient phone rejects this SIM too. :-( At this point the rational course of action ought to be to trace the SIM-ME communication between the finicky phone and one of each kind of SIM: the kind it accepts, and the kind it doesn't accept, and see what it barfs on. But I just realized a problem: there is a very high likelihood that the ancient phone feeds 5V to the SIM (Nokia 2190 is powered by a 5-cell NiMH battery, so it has plenty of voltage headroom inside to put out 5V), and my reading of Atmel's datasheet for the SAM3S chip on the SIMtrace board tells me that 5V will fry it: the electrical specifications chapter of the datasheet lists 4.0 V as the Absolute Maximum Rating for all pins, including those GPIO pins that are wired to the phone connection on the SIMtrace board. Just checking to see if my understanding is correct: is SIMtrace v2 indeed absolutely NOT tolerant of phones that put out 5V toward the SIM? Not tolerant to the point that it would not simply not work, but would *fry* the SAM3S chip? If the board part of SIMtrace v2 kit is of no use with ancient phones that put out 5V, I reason that I should still be able to make use of FPC cables: I just need a little adapter PCB that hosts a SIM socket and a connector for the FPC to go into, with accessible points for probing with an o'scope or a logic analyzer - it just needs to be a purely passive, connections only PCB, without any ICs that would be fried by high voltages. Would anyone happen to know if I can still buy such an adapter PCB anywhere (I read that such were used in the beginning of the project before the first custom SIMtrace board), or will I need to spin out that adapter PCB myself? TIA, Mychaela

RemSIM SIM Originating Traffic
by Marc Wilson 28 Sep '22

28 Sep '22

Hi Harald, I'm hoping you may be able to give me your insight into something before I start a debug process. I have observed several instances where commands/traffic issued by the SIM are not implemented (seemingly not received) by the modem whilst utilising the RemSIM connection. Two examples I have recorded are of a UICC reset (refresh type '03' (= NAA Initialization)) and of a proactive 'open channel' command. Is this something that you would expect within the application (essentially a single 'initiation' traffic flow - modem to card but not card to modem)?

Project based on Simtrace v2
by Cretu-Torica Alexandru-Gabriel 09 Aug '22

09 Aug '22

Hi, I am Gabriel from Rapid Prototypes Ltd. from Cyprus; I have decided to contact you because I need assistance regarding the Simtrace v2 device. We have a Project and I don't have for now the qualified person which can help me with this project which is based on Simtrace v2, and , I do hope that someone can provide me the requested assistance and in this case I can pay very very well . Please let me know if there is someone available to work on this project: - basically what I need is to connect between them two Simtrace v2 device's, which communicates between them, one Simtrace v2 device which I will use like a Transmitter and this device it is in a country , but other Simtrace v2 device, which I will use it like the receiver, it will be in another country; So , what I need is that the two of them are connected over the Internet, doesn't matter how (using a Raspberry or etc.) and one Simtrace it is used to read a Smart Card and to send in real time the data to the other Simtrace which will act like a card emulator; Please let me know if you are able to work on this project, Thanks

Simtrace2 Projects
by Marc Wilson 08 Aug '22

08 Aug '22

Hello, I am currently working on several projects for IoT based solutions using the SIMTrace2 board and software. I have not been able to locate/install the SIMTrrace2-remsim application. Whilst I have SIMTrace2 itself installed and functional there is no reference to the remsim function. I am using binaries from the Raspbian 11 repo. The related wiki indicates that remsim would be part of the SIMTrace2 installation (albiet referencing the method of compiling locally). However, I find no reference to it in my standard installation. Would it be possible to point me in the right direction to install this function? Is there an alternate version of the software required to do this? Many thanks, Marc Wilson Marc Wilson Technical Consultant t: +44 1483 802 503 | w: eseye.com LinkedIn | Twitter | YouTube | Blog This email is from Eseye .

osmo-remsim-client-st2: USB OUT transfer failed, status=2
by Lorenz Dumanski 30 Jun '22

30 Jun '22

Dear osmocom team, I am trying to set up the osmocom-remsim application. The goal is, that the phone uses the SIM inserted into the card reader and connects to my EPS. I am using a SCR 3310 Card Reader and the simtrace2 hardware. I setup the bankd and the slotmap according to the manual. It seems, that the mapping is fine although, when I start the client, the execution terminates with "USB OUT transfer failed, status=2". The phone does not recognize a SIM inserted. Setup: Debian 11, simtrace plugged into the computer. Simtrace is attached to a mobile Phone (Samsung galaxy A90 5G or Apple iPhone 13). SCR 3310 has a sysmoISIM-SJA2 card inserted, which is configured to attach to a custom cell distributed via srsRAN. Note that the OS is hosted as a VM with KVM/QEMU. When using only the simtrace, without remism, the SIM Card which is inserted into the board works as intended and the phone connects with my EPS.

RFC: Reviving OsmoDevCall
by Harald Welte 25 Jun '22

25 Jun '22

[please follow-up-to openbsc(a)lists.osmocom.org so we don't cross-post all related mails] Dear Osmocom community, OsmoDevCall used to be rather successful for quite some time in recent years, but recently has been suffering quite a bit due to insufficient people volunteering to present. Big thanks to all who did! Interestingly, there's no shortage of ideas of topics at https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCall - but then many of the potential speakers did not have the interest or time to follow-up. Most recently, the last few instances have not been taking place due to a lack of volunteers during my holidays. Last, but not least, while during COVID lockdown winter "friday night 8pm" was a good idea, this of course is more difficult during the summer, when people are more likely want to go out the weekend. So, to summarize, let me ask some questions: * would you be interested in OsmoDevCall continuing? * which day/time/timezone would you prefer ? * would you be able and willing to volunteer to give at talk within the next 3 or so months? Any other suggestions for or around OsmoDevCall are of course also welcome. Thanks in advance, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Support about USIM applet installation on sysmoUSIM-SJS1
by Matteo 15 Jun '22

15 Jun '22

Hi, I was trying to install a custom applet on sysmoUSIM-SJS1 SIM cards. Following the guide present here <https://osmocom.org/projects/sim-toolkit/wiki> and using shadysim I was not able to do that ( it gives me an error related to the fact it doesn't receive any status word back after sending an APDU, I think it's a bug but we can discuss about that later). I ended up using Global Platform Pro to install it but it only loads the applet on the card as a module of another package and doesn't make it selectable. I also tried to upload the applet suggested by you in the guide, but I got same result. Is it something related to the sim card? Should I buy the SJA2 version? Can you help me? Thanks, Matteo

by kbcware＠yahoo.com 26 May '22

26 May '22

Hello, By any chance, is anyone selling a Simtrace2 hardware kit (new or used, as long as it is working)? I really urgently need it and would be willing to pay a premium to have it shipped asap to Toronto, Canada. I’ve read that the osmocom webshop staff is on holiday, so I would really really appreciate if someone can help me. Thank you so much!
