What brings my attention here is that apparently the receiver is seeing only one message (comment #7). It is possible that the receiver phone detects receiving 2 messages that are exactly the same and shows only one, but I would say that is not usual.
I would like to know if in some case the receiver shows more than one message. It is not impossible that the operator is wrongly charging for non-sent SMS. On the other hand, in the attached files it can be seen that messages are retried in quite regular intervals (between 5-7 seconds). It is possible that somewhere in the stack there is a 5 seconds time-out and the message is retried without actually waiting for some response from the modem, which is what should be done. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to telephony-service in Ubuntu. https://bugs.launchpad.net/bugs/1480554 Title: High costs due to SMS being sent multiple times when having a bad network connection Status in telephony-service package in Ubuntu: Confirmed Bug description: When having a bad network connection, Ubuntu tries to send SMS multiple times but fails to recognize which messages have already been sent, resulting in very high costs due to the same message actually being sent several times. I found this when looking through my provider's monthly reports and I remember being on train journeys with very bad network connections on these days. See the attached screenshots. ========== This happened on a Nexus 4 running on the stable channel (with up-to- date images at the given times).
