AttributeError: module 'enum' has no attribute '__version__' when installing pySim
by Young Hwan Kim 03 Feb '25

03 Feb '25

Hi. I want to use pySim to check my own SIM applet. But there is ERROR when installing pySim. pySim requires smpp.pdu-0.3. So I tried to install smpp.pdu-0.3. But it show following error like following. Error is due to "AttributeError: module 'enum' has no attribute '__version__'" Could help me solve the problem. (vpy) quectel-sw@quectelsw-keipy:~/work/04_usim/smpp.pdu-0.3$ (vpy) quectel-sw@quectelsw-keipy:~/work/04_usim/smpp.pdu-0.3$ sudo python3.9 setup.py install --user running install ..........

Any insights or advice would be greatly appreciated. Thank you!

SysmoOCTSIM enumeration issues
by Sohail Arshad 20 Dec '24

20 Dec '24

Hello, In reference to this bug: https://osmocom.org/issues/5310 I am also experiencing this on two different platforms, Pi4 and an Intel NUC x86. I have two OCTSIMs but I can reproduce with one only and with only USB connected. All SIM slots are populated. Upon power cycle of the host system, the OCTSIM is unable to enumerate. If I unplug the USB cable and replug, it sometimes enumerates. If it doesn't, I move to another USB port and sometime it works. I also tried upgrading the firmware on one board from 0.2.61-2a78 to 0.2.78-62e1 but the problem remains. Log below shows enumeration errors after which I unplugged the cables and replugged. Please advise as we cannot build a product around a device that cannot enumerate reliably.

WiFi calling in iPhone
by Koji Tsubouchi 30 Oct '24

30 Oct '24

Hello experts, I am trying to use WiFi calling in iPhone by using sysmoISIM-SJA2, but for some reason "WiFi Calling" toggle button is not shown in the phone setting. I am using PLMN ID 441-216 (Newly obtained from Japanese Government for private network usage). I have written epdgid, epdgSelection, and pcscf address in the SIM card and saw if the toggle button was shown, but it was not. It would be really appreciated if you could tell me how to enable WiFi calling in iPhone. Thanks&Regards, Koji

Hello, I have a functioning setup of remsim as follow: * An x86 server that hosts a sysmoOCTSIM board. This server runs the bank daemon and also the remsim server. * An ARM64 client that hosts a SIMtrace2 board, and a 5G modem with two SIM inputs to support dual SIM single standby (DSSS). The SIMtrace2 connects to SIM slot 0 on the 5G modem via a flexi. * I use the remsim-apitool to create the slot map and assign SIMs to the client using the server IP, bank ID and client ID. Client slot is always 0. I’d like to allocate two SIMs in the bank to this one client using only one ATSAM4S microcontroller to utilise the DSSS function of the modem e.g. SIM slot 1 in the bank is mapped to SIM slot 0 on the 5G modem for client ID 1. SIM slot 2 in the bank is mapped to SIM slot 1 on the same 5G modem for client ID 1. Is this possible with the current implementation of remsim? I cannot find any reference to this in the archives or in the manuals. Thanks The contents of this e-mail are confidential and for the exclusive use of the intended recipient.
