Need help Galaxy s7 sm-g930F not working for at&t

[s7930f]

I got a sm-g930F model and its not working with my at&t sim. Tried calling customer care and went through some apn settings but it didn't work. Help appreciated.

Has this phone been used before? If not, it needs to be 'activated' (first call made) in the region it was intended for sale (from the model, I'm guessing Europe) first before it can be used with any other SIM card.

I don't know. Is there a way I can check that ?

What sim did it work with?

 

[s7930f]

seller said it worked on at&t. bought it on craigslist.phone does look like used.

Do you have any other SIM that you can try it with? Maybe from another company and see if it 'takes' the configuration?

Let me guess. You bought a phone from a complete strangers and did not test to see if it worked. Genius.

Is it throwing up any error message at all?

Have you fixed this problem, OP? Please advise so that we can provide further assistance.

Not fixed yet. Only calls and texts are working. LTE is not working. Intermittently some slow speed internet is working. No error messages at all

I would visit my local AT&T store and see if a new Sim card would fix the problem.

Does it have a option under settings to hit activate?

 

[s7930f]

It doesn't have activate under settings. I also visited at&t store and tried a new sim.

I just noticed that there is no 'Mobile Networks' option under Settings, not sure what that means. Also my computer is not recognizing this device when I connect with the usb data cable.
