I cannot receive MMS Messages on my Surface Duo

Hi Everyone,

I am continuing to have problems receiving MMS messages (group texts and pictures sent to me as part of a group text) on my Microsoft Surface Duo. I have one of the unlocked models that I use on Verizon.  I've researched the issue, and it appears that the issue is (1) I needed to activate "CDMA-Less" on my phone and (2) I needed to modify my Access Point Network (APN).  After several calls to Verizon, I was finally able to enable "CDMA-less" on my phone, but they could not help with my APN modifications. I am unable to modify my APN settings on my Surface Duo--those options are "grayed out."

Verizon directed me to Microsoft to help me with this issue. I called the 1-888 customer service number, but when I chose the option for tech support, they told me at had "moved online." After many many many attempts, I have not been able utilize the chat component of customer service. It keeps telling me that "sorry there this a technical error." Consequently, I cannot get customer service support for my issue.

That's why I am turning to the community forum again to see if I could please get some assistance with my issue that I have been struggling with for going on two months now.  I am unsure of what to do next.

Thanks for your help,

R
