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!
Regards,
Harald

(ETSI EN 300 175-7 Ch. A6)
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
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
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

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.
Configuration:

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

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
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!
Hello,
I’ve recently acquired a simtrace, but I can’t get it to work at all under OS X.
I’ve tried Kali, but simtrace list shows 0usb devices.
For OS X there’s a ton of dependencies that I can’t find. And on Kali I’m a real novice.
Is there a more elaborate tutorial somewhere for me to use?
Thanks,
Mat.
