[iMore Question]

I had no trouble with internet connection when I traveled away from my home for two years. Suddenly, I can't connect to the internet. Other people around me are connecting fine, but my phone says no connection and no WiFi. My WiFi is on. I must have hit a setting somehow and turned something off. What is it that I need to turn back on?

Go to settings General-Rest then choose Reset network settings.
This will reset all your network settings and you'll be required to enter the password for any previous networks you where connecting with previously

Check:

Settings > Cellular > Cellular Data > [ON]

You do have cellular service from a provider, correct?

Also works for Android phones. Screwed up connections with Android Play for my car and was unable to connect to internet. Spent half-a-day trying to sort it out and found the above posting. Followed the instructions and "Presto!!" I'm connected. Thanks!!
