Samsung Galaxy Note 4 Internet not working

Question

Yesterday I received an update from Samsung for Note 4. Since then the mobile does not connect to the internet, only if I do it through wifi. I've rebooted it, I've connected and disconnected the mobile data, and nothing.
The latest updates installed are:
N910FXXS1DQB4 /
N910FPHE1DPL1 /
N910FXXS1DQA4
This is what tells me when I look at what update I have.
What I can do?

Answer 1

Hello , when you say that you do not connect to the Internet, you can not, for example, navigate with your usual browser or that you do not see the mobile data connected above (typical arrows).
If so check in settings .... connections and mobile networks that have them activated and within "access point names" verifies that you have selected your mobile company OK.
Maybe I deleted it with the update.
I just watched and in my Note 4 I still did not skip that update. I still have the previous one.

Answer 2

Hi , you got it right. In "access point" was marked Movistar. I dialed on Telefónica Movistar and it has appeared "4G". A lot of thanks again.

Answer 3

Great has been solved.
Maybe because it was a custom update Operator, had that default apn and not the one that should be.
