This is kind of vague on what you are asking or what your problem is. If you are trying to activate a new card you will need access to wi-fi, switch your phone to wi-fi and you should have access to the network until after SIM card is activated. If your card is activated and you are able to call and text but still don't have internet access, go into your settings, click on network and internet, click on mobile network and make sure mobile data button is toggled on.
If you are having a different issue with getting onto the network you will need to be a little more specific on what the problem is. Good luck!
