Why is my verizon unlocked Note 4 not working on At&t sim?

[abzdan]

I have an Unlocked Verizon note 4, right after activation it worked fine with my Att sim. Just minutes later it did not read my sim.
I checked with Verizon and phone is not blacklisted. But they tried a verizon sim in it and it worked just a minute only, after that it said No Sim Found.
Weird right.i even sent the phone to Samsung and they said phone is working fine.
If that is so how come it wont accept a sim???

Try nabbing a new AT&T SIM. It may just be that SIM having the issue.

Try changing the apn settings to the carrier you want

Hi it wont even let me do that. I cannot creat an apn because it has no sim.
And that is the problem of the phone it wont read a sim

It sounds like a hardware problem, if it won't read the sim. Verizon will send a replacement, if you have service with them. Otherwise, you can get it warrantied through Samsung
