I have an I-phone SE, and whenever I get outside of a WiFi network, the phone says I have no internet connection. I have tried getting a new SIM card, but that hasn't helped. I'm wondering if there is a setting on my phone that is not right. Help! I'm getting ready to go back to my old carrier. Their coverage wasn't as good, but I never had a problem connecting to the internet.
I know nothing about iPhones. I think even with those phones you need to turn off the wi-fi so it can switch back to mobile data. Also make sure mobile data is turned on in your network settings. I know on my android phone if I turn on wi-fi it turns off mobile data. to get mobile data back I need to turn off wi-fi.
