Are Sailfish SMSs weird in any way?

I send a lot of SMS via dbus, the exact command is:

sudo dbus-send --system --print-reply --dest=org.ofono /ril_0 org.ofono.MessageManager.SendMessage string:“0046801234567” string:“Hello World”

It works like a charm, I love it. I have a little java stack that logs in to the phone and I can send messages via a swagger page.

The issue is that around a month or two ago I noticed some SMS didn’t send. In fact, if I sent a few messages in a row, one might send and then one or two would get ‘stuck’.

The weird part is this, once this issue starts even sending manually via the SMS app fails, and I can take the SIM out of my Jolla and throw it in an iPhone, and the SMS still won’t send, even from the iPhone via its messaging app.

To me, this means the issue is network-side, which makes me wonder if these SMS are getting flagged as being weird in some way?

It’s not volume, I am just sending single SMS, and it’s just normal numbers, 90% of them are to three or four BFF numbers…

It’s so inconsistent which SMS goes through that it makes me think either the network is flagging my number for some reason, or that the dbus-sent SMS are different from ‘normal’ SMS and are causing issues.

But AFAIK, the dbus-SMS are just identical to any others.

Any ideas very welcome, it’s a weird and annoying issue.

edit just to add, I tried calling Comviq and they were clueless. Will change network to see if that helps but also wondering if Sailfish or command-line dbus has some weird header.

I’m curious what your findings will be

I can only assume it is VoLTE-related.
Also make sure to print/log the result of that dbus call if you aren’t already.

Not much there…
