Sorry for my English. I use a program for sending SMS. To one computer I have connected more than 100 modems.
When I want to replace the SIM card on the same modem, I'm sending the device to suspend, change SIM card and wakeup the device again.
The modem receives a new command initialization and continues to run, but he gives IMSI of the old SIM card.

AT+CIMI return current IMSI but new files sent/report/incoming is still IMSI of the old SIM card. To get a new IMSI I need to do a restart of the whole service. This no problem for 1-5 modems. At 100+ modems it takes a lot of time on all devices, and causing long delays when sending large number of SMS. Good to have a configurable option - wakeup_read_imsi for this.

Thank you.

Nice to hear that there is one more real heavy user of this software. 8)

Here is a new version for you:
Hidden private text.


I do not yet make it public, but likely soon it will be released, as maintainers of GNU/Linux distributions are preparing to upgrade their repositories.

It has a modem setting:
wakeup_read_imsi = yes

With this setting IMSI is read every time when a modem is initialized. Reading takes only couple of milliseconds, so I was thinking that there is no reason to check if a modem was suspended or not.

I tried this version of the program. Not comfortable displaying messages IMSI in the log with level 5. No need to display it in the log always. Only 1 time upon awakening. Smstools is important to read and remember the new IMSI when the modem returns to sleep mode.

Log on 3.1.16


log on 3.1.18-rc1



to many spam IMSI: *********034335 message


a good log should look like this

Thanks for your opinion. The package on the private link is now upgraded. It is using the same name as before.

Setting wakeup_read_imsi is removed. There is a setting read_identity_after_suspend which defaults to yes.

Please try the new version, and also any other comments are welcome. 3.1.18 will be released within a next few days.
