Calling, texting, mms, & data NOT working. Using AT&T SIM card in Samsung Galaxy J7 (Verizon phone)

I am using my AT&T SIM in a Samsung Galaxy J7 V (from Verizon). When I got it I changed the APN Settings using what is provided on AT&T's website. It was working fine for about a week and then a text message wouldn't send, couldn't receive messages, or use mobile data. I tried doing a reset on the phone and re-entering the AT&T APN Settings. About Phone section in settings has my phone number, phone says network connected. Still NOTHING. 
Why did it randomly stop working and WHAT DO I DO?

Hi @kgissandaner


Thank you for reaching out to us today. Since you've already trying re-entering the APN settings and resetting your device, your best bet is probably going to be visiting an AT&T store to let a tech look at your phone in person. However, you can also try using our troubleshooting diagnostic tool.

The SM-J337V model comes back as the J3, not J7.  That phone made for Verizon doesn’t have bands 12/17 for LTE which is the primary band for AT&T data.  This would certainly effect all the systems you mention.
