Tested with two different numbers from different German provider networks - O2 and Telekom (apparently, could be a ported number) I can ask what network they are using if needed


the initial version of this bug report was created using Bugger 0.9.9+git4

It sounds very similar to SMS sending not working on xperia 10 III – with VoLTE on
Can you confirm?

Ah, didnt see that one. Thanks!
basically, yes. Sounds like the same issue.
I could reproduce it reliably though

Cannot confirm with Vodafone, Germany, VoLTE, 4.5.0.19, Xperia 10 III

I had once a sm which stayed in a state of “sending in progress”.
I resent three times but the message was received on the other side three times.
All other messages webt well.
