Switched to Sprint with BYOD iPhone X and can't send MMS

[mase2201]

I switched to Sprint from Verizon and brought my own iPhone X. Since the switch, I can't send mms; this includes pictures to non-iPhone contacts as well as replies to group messages that include a non-iPhone contact. I've contact Sprint via phone support, I've had a ticket open for over a week now with several different support teams calling, trying a couple of things,  and escalating to another team. This has gone on now for over a week and is very frustrating! They have had me reset all network settings on 2 separate occasions (and advised me after the first time that I would lose all stored WiFi passwords), ##update# several times, turn MMS setting off and back on, unpair my appleWatch, now I'm told I need to do a hard reset on my phone (wiping all content and setting it up like a new phone.) This seems very excessive for simple carrier switch.

Has anyone had a similar experience with MMS not sending after bringing a phone from another carrier? If so, how did you resolve it?

If you sign completely out of your Apple ID, can you send MMS?

@Em_Will_I_Am What additional steps would I need to do to sign completely out of apple ID beyond Facetime and iMessage?

Settings - iTunes & App Store - Tap on your Apple ID - Sign Out.

Or 

You can always reset the device as new via iTunes.

@Em_Will_I_Am No, I cannot send a MMS while signed out of iTunes & App Store.

Any error message?

It just never completes. This is nearly 24 hours later and you can see the green progress bar still. When I do get an error message it's, failed to send.

Ahhhh, I see the problem.  You are a Bears fan.  My apologies and condolences. PM me your number and I will get a ticket created for you.

The backup is not the issue because I had the MMS issue before the restore. Here's the chronological order:
