Hello @dafedel  

First turn the phone Off and On i.e a Soft Reboot, but if that does not help then follow this by trying a forced reboot by holding down the volume down key and power button simultaneously for more than 7 seconds to restart it. When your phone resets, you will feel it vibrate.

May I suggest to perform a forum search as you may find already existing threads with help and advice within. 

If you pop your Sim Card into another phone does Mobile Data then work 🤔 

Does Mobile Data not work in a particular area or everywhere. 

In Settings > Connections > Data Usage > Is Mobile Data Data toggled On. 

Some troubleshooting steps. 

Settings > General Management > Reset > Reset Mobile Network Connection. 

See if that helps. 

Ultimately back up and factory reset but don't use any back up to set the phone back up i.e set up manually. 

If i can be of any further help please don't hesitate to ask  😎
