MMS not working - Never had an issue until late December

[#1]

I am having an issue where I am not receiving MMS (Galaxy S8) while in my office.  It appears like the service cuts out, however, never had an issue until about a month ago.  I receive multiple MMS texts a day and am unable to view until I go outside.  Are there any settings where I can push these MMS through or re-calibrate to push through service?  

My service is Xfinity Mobile.  If I can't find a solution I will be forced to change carriers.  Please advise with support.

Thnaks,

Weird it's only happening in your office, are you connecting to WiFi at work?

It seems more like your phone either has lost its MMS configuration or Optus isn't pushing the MMS through to you properly. And now your clicking on the link with WiFi connected it's probably using that which can't reach the Optus MMS Server, so when your "outside" your off the WiFi network and it works over 3G/4G.

I would ask Optus technical support to "delete your profile of the MMSC", then check your phone has the right MMSC settings and send an MMS to yourself. This will then "Recreate your profile" and you should be good to go.

^ how do I know this? Former mobile tech support rep, and fixed things like this on a daily basis.

Hi buddy, did you try clearing the previous time cache file, or on the wifi network?

Mms do sent work over wifi on Android, only on Apple.  Also, yes, I cleared the cache.  Any ideas?
