EM7455 Can't send sms with mmcli on verizon

IoT Modules MC/EM Series
1

I’ve been trying for hours to get mmcli to send a text via terminal on Verizon with no luck. It works with AT&T. I have a data connection on Verizon but no sms. Any guidance?

When I try to send via

mmcli -m 0 --messaging-create-sms="text='Hello world',number=+1xxxxxxxxxx,delivery-report-request=yes"
Successfully created new SMS: /org/freedesktop/ModemManager1/SMS/1
mmcli -s 1 --send

It hangs for a long time then says:

error: couldn’t send the SMS: ‘Timeout was reached’

sudo mmcli -v -s 1 --send
[06 Oct 2021, 23:24:14] [Debug] Assuming '1' is the SMS index
[06 Oct 2021, 23:24:14] [Debug] ModemManager process found at ':1.14'
[06 Oct 2021, 23:24:14] [Debug] Sms found at '/org/freedesktop/ModemManager1/SMS/1'

error: couldn't send the SMS:
'GDBus.Error:org.freedesktop.libmbim.Error.Core.Timeout: Couldn't send SMS part: Transaction timed out'

If I try to send via AT commands it says there’s no room. When I moved back to another phone or other device running Linux with a different modem it sends with no problem with commands above. All msgs come in and send once the sim is placed in another device.

Here’s the details from mmcli -m 0

Hi kabone01,

Please refer to +CMS ERROR: 350 when sending sms

Donald I have tried following what has been recommended on the previous threads.

I removed the + from the SMSC:

+CSCA: "9037029920",129

I then receive:
+CMS ERROR: 305

As for upgrading the firmware. I want to verify That I should be using the ones from here:
https://source.sierrawireless.com/resources/airprime/minicard/74xx/airprime-em_mc74xx-approved-fw-packages/#sthash.OSzMN45y.dpbs ? Because I do not see newer firmware for the EM7455. These posts you link are using MC73XX not EM74XX, so I just want to verify I should be using the link above and not the ones they link to?

Hi kabone01,

You used the latest SWI9X30C_02.33.03 GENERIC EM7455 firmware.

+CMS ERROR: 305: Invalid text mode parameter
Please check the SMS mode parameter again.

I was able to send an sms now via AT Commands, but I am still getting the same error with mmcli. Is there a way to fix this?

EDIT
I’ve managed to get it working with gammu so it will work for me.

Definitely looks like my issue was the smsc
