Why is mobile internet not working on iphone?

Question

iPhone

I bought a phone from my hands. Everything is in order as it was. Several months have already passed. There was a need for mobile Internet. I threw the balance, tried to load some kind of page, but nothing loaded.
As a result, the balance was exhausted ...
I bought a new SIM card, connected the tariff for the Internet. I tried to go somewhere again, but again, there is just a request but nothing is displayed, just a white background, but the traffic is being eaten up ...
Everything is in order with calls, everything is loaded via wifi, but mobile Internet is not in any doesn't want to work.
What could be the reason and how to fix this problem?
PS. Phone Iphone 6. Operators: beeline, tele2

Answer 1

We go to Settings.
Select Cellular.
Find Cellular Data.
Switch the slider to active mode to turn on the Internet.
Or change the network .. from LTE to 3g
visited ..?
or the "Basic settings" menu, where you should select the "Reset" tab, and then click "Reset network settings". Such a measure allows you to reset all connection data in which a system error could occur.
