Sure thing. I couldn't catch them the first time so I got some for you under controlled conditions. I should note that the number I am sending too is on a different carrier than the recipient of the first error. Also, I can successfully send both over-length SMS and under-length SMS to this person.
SS1 file is my first test message tonight and the error from 502. I ended up getting 15 messages from 502 about that one.
SS2 file is after my second test message and the message count from 502 at that point.
SS3 file is messages from 502 from my vertical monitor to show how many I had gotten (or would, they go on a bit if I scroll up) from 502 about the two messages combined. Total of 25 messages for both test messages combined.
Thanks!
Edit: I hope this is how you wanted them embedded. I attached them to the comment but they didn't show up, so I embedded them as well.
