Every time I leave Wi-Fi my mobile network does not connect, only been happening the last couple weeks. It only happens when I'm roaming outside of United States.
- Roaming is turned on
- switch to mobile network if weak Wi-Fi signal is turned on
- global Network is also on
Have you checked for any available updates?

If neither of these change the symptom, I would recommend contacting your carrier regarding this.
