Windows 10 Mobile: Fixing no data connection

After the last upgrade on my work phone to Windows 10 build 10166, somehow my data connection stopped worked. After an initial first line troubleshooting involving a few restarts and fidgeting with the data connection, I decided to let this one rest since I mostly tend to use my work phone with wi-fi anyway. However today I was in need to use my phone’s data connection so I had another go into fixing this issue. and I am happy to say that I resolved it quicker than I expected.

After an initial search on the subject, I read something about data connection not working over roaming after the last update. Thing is, I am not roaming but I decided to try switching data roaming off then back on again to see if this would fix my problem. However prior to that I thought that maybe the phone region is misconfigured? Either way I decided to look at that first, since having the incorrect region on your Windows Phone can be a pain — particularly when the phone tries to “fix” phone numbers mistakes via the international assist settings.

So I went to settings, time & language, region and I noticed that the incorrect Country/Region was selected. I changed it to the correct country, and restarted the phone as per the instructions. After rebooting, voilà! The data connection was finally working again.

Why do this happen? I’m taking a wild guess here, but I think that the data roaming glitch I mentioned above might be an issue, and the Windows 10 Mobile OS might check whether a phone is roaming or not by checking the region configured on the phone against the network carrier first, instead of simply querying the network carrier. Either way, I hope this solution can help others who might be stuck with this issue as well.
