This post has been moved to “Norton Mobile Utilities” board for better exposure
Hi jomarknm.
Welcome to the Norton Community Forums. 
As your question is about Norton Mobile Utilities (NMU) I am going to ask for the thread to be transferred to the NMU forum for better visibility. A marker will remain here so that you can get there quickly from this forum if you wish to.
As for your question I was not aware of this happening but as I do not normally use mobile data I cannot say that I have checked it recently. Have you been using NMU for long? Did this work in the past but then stopped or are you never aware of it working?
Does the amount of data shown look right? Does it appear to reset at any other time?
Finally, as I think I have asked enough questions for now what version of NMU are you using and is your device rooted?
I look forward to hearing back from you.
PS if whoever hit the "me too" button could add any further details it might be helpful. - Thanks.
Thanks for your reply.
Here are the answers to your questions:
I have had the Galaxy S4 active for only a little more than one month and this is the first time on this phone that I noticed the problem. However I did have Norton Mobile Untilities app on my previous phone (Samsung Infuse) and there were no issued with the resetting of all data on the 19th of each month.
On the Galaxy the data has not reset at any other time
Version 2.7.1.362
My phone is not rooted.
Thanks for the clear and helpful response jomarknm.
It would appear that the issue is the new device. I will do my best to draw this to the NMU team and hope that they can find a fix.
One last question - what have you set as your Monthly data profile and is the same as you had on the previous phone that worked well?
Do keep us advised of any changes.
My data is set at 200mb and that is the same setting that was on my previous phone.
Do you think the problem might be solved if I uninstall the app and then reinstall it?
Thanks

If you have not tried that it is well worth trying. Do keep us informed.
I have alerted the team that there may be an issue with your device but if you can fix it with a re-install that would be great. Pity it is such a long way to the 19th!
Good luck.
Thanks. I will uninstall and reinstall the app. Depending on what happens I will recontact you if necessary.
Good luck. But do let us know whatever happens so we will be in a better position to help others. And so the team know if they need to do anything!
Look forward to hearing back from you.
Hi jomarknm,
I did try to reproduce the issue with an S4, but did not see the issue. One thing you could try is to change the Billing Start Day to tomorrow and wait to see if the Mobile data will be reset. Hopefully after the reinstall it will, but if it does not can you please provide some more information regarding your device:
What carrier is your S4 on?
What Android version is installed on your S4?
