Turn on cellular data in the Settings app.
If this doesn't help, contact your carrier and ask for help. You can also restart/reset your iPhone.
Alternatively, you may go to Settings - General - Reset - Reset All Settings

If this does not help, restore your device to factory settings. Note that this will erase the data from your device.
Take a look this Apple Support article: Use iTunes to restore your iPhone, iPad, or iPod to factory settings - Apple Support.
