So the Lumia 900 has been on sale and has gotten to the hands of consumers since last Friday, and many have been complaining about not being able to connect to the internet.
At&t's "go-to" fix is for you to reset your phone, but that doesn't seem to fix the problem.
"WinSourceVideo" have put out a video showing how to fix this issue, they found out what's causing the issue, and it seems some Lumia 900s have the Data settings configured incorrectly.
So here's a quick fix to the issue:
I didn't get any data connection issues with my Lumia 900, but if you did, be sure to try manually configuring your APN as described in the video!
- APN: wap.cingular
- USER: email@example.com
- pWORD: cingular1
Hope this helps!
