Nighthawk M5 AT&T Looking for APN

For SafeLink Wireless, I pay for the extra unlimited data allowance, I'm also using the Verizon tower coverage, but it shows no signal nothing, when I had the T-Mobile coverage towers and sim variant I was able to get a signal and data coverage.

Does the m5 version support Verizon or am I entering the wrong apn settings. 

I've tried; 
Name: 1. Safelink, 2. Safelinkvzw, 3. TFDATA

APN: 1. RESELLER, 2.TRACFONE.VZWINTERNET, 3. TFDATA
PDP: IPV4V6

PDP Roaming: IPV4V6

None are wanting to work.
