I've found a ton of posts regarding this with other devices but the solutions don't work for me.

I can receive texts
Use internet (lte 20mb down 7 up)

I cannot make or receive calls
Cannot send sms cause code 65535

On other posts I read about a plus sign in the numbers (not my problem)
Reboots I've not only tried reboots but factory resets.

Any ideas? I've had my DNA for months and I've never even crashed once before today

I am having this same issue. I am not sure about making calls, but I cannot send texts. The number I am sending to does not have +1 in front of it. I updated a few days ago so I do not know if it is related to the update. I can receive texts.

While I'm sure you tried a number of things did you check your 'Mobil' Network setting that it's CDMA/LTE ?
