Simply because you're using cellular data, it is normal for iPhones to get warm when using cellular data. Mainly
If you use cellular data and the connection isn't very strong, it will get slightly warmer than having a strong connection.

The phone will get warm when in use. But if you feel that the phone is too warm or hot, make an appointment at an Apple Store to have your phone checked out.
