EM7455 - Can’t Send SMS With mmcli on Verizon but Data Works

Post by kabone »

I've been trying for a few days 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

Code: Select all

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:

Code: Select all

error: couldn't send the SMS: 'Timeout was reached'

Code: Select all

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'

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 from another modem with the same sim after the above attempts:

So I managed to solve the issue. I needed to flash Verizon firmware rather than generic firmware.
