This is very easy to reproduce for me, on At+t network. Not sure if it's an operator issue, nuntium issue, or udm issue at this point. Here are the steps to easily reproduce it for me:
1) from another phone (phone A), create a Group Chat message to your ubuntu phone and one other phone 2) send 4-5 messages in rapid succession (i.e. "one", "two", "three", "four", "five") from phone A 3) on ubuntu phone, verify that all messages are receivied, otherwise you'll see a message from "Unknown Number" with body "message not found" Repeat steps 1-2 until you receive the "Unknown Number/message not found" message in messaging app. For me this happens usually after 2 or 3 cycles Based on my logs, it looks like download mgr downloads the messages, and nuntium tries to upload a reply (assuming it's an ack reply). This fails according to the nuntium log: 2016/01/11 16:59:59 Starting download of http://166.216.166.67:8006/1113152245600010000030000 with proxy 172.26.39.1:80 2016/01/11 17:00:00 Progress:60 60 2016/01/11 17:00:00 Progress:60 60 2016/01/11 17:00:00 File downloaded to /home/phablet/.local/share/ubuntu-download-manager/Downloads/1113152245600010000030000 2016/01/11 17:00:00 Created /home/phablet/.cache/nuntium/store/9d454e8dff12878113d91725fa5fb3f6.m-notifyresp.ind to handle m-notifyresp.ind for 9d454e8dff12878113d91725fa5fb3f6 2016/01/11 17:00:00 Starting upload of /home/phablet/.cache/nuntium/store/9d454e8dff12878113d91725fa5fb3f6.m-notifyresp.ind to http://mmsc.mobile.att.net with proxy 172.26.39.1:80 2016/01/11 17:00:00 Progress:8 8 2016/01/11 17:00:02 Cannot upload m-notifyresp.ind encoded file /home/phablet/.cache/nuntium/store/9d454e8dff12878113d91725fa5fb3f6.m-notifyresp.ind to message center: NETWORK ERROR In the corresonding download manager log (using tail -f .cache/ubuntu- download-manager/*), it appears the initial download was correct and I don't see any failures: //FAILED MMS Message I0111 16:59:59.504356 1808 manager.cpp:224] Create MMS download == {url: http://166.216.166.67:8006/1113152245600010000030000 hostname: 172.26.39.1 port:80} I0111 16:59:59.505923 1808 manager.cpp:131] Owner is: :1.383 I0111 16:59:59.506072 1808 factory.cpp:70] Factory assigns the Download Uuid.
