Using a Verizon HTC One M8 on ATT..

Please post the step by step setting of APN settings in Verzon M8 phone for at&t network. I am not able to connect to data.
 
Currently using the M8 on cricket (AT&T)
Didn't have to do anything but add the apn settings once I put in my sim.
Currently only getting HSDPA but I have no complaints. Phone is speedy and the data I'm getting real fast and reliable. But no LTE.
