Help 3G connection issue since JB update.

[scottbufc]

Hello all

Updated to JB today and since that the phone will not connect to any 3G or roaming. Very annoying. This must be due to the update as it was fine previously.

Android 4.1.1
HTC Sense 4+
Software 3.14.401.27

When I go into mobile data on the settings it just says disconnected.

I also dont like the new keyboard and that some keys have moved but I can deal with this. The lack of 3G I cannot. JB seems much more hassle than what its worth. Any advice?

Thanks a lot.

Something must have went wrong during the installation because I ran JB for a while and 3G connected fine. Are you rooted or anything? And in the settings where it says "Mobile Data", does it allow you to tap it or is it greyed out?

Have you tried all the usual things like a reboot, or a long press on the power button to simulate a battery pull.

Try settings long press on mobile data & change network mode to wcdma only see if that fixes it first.

The only other thing is a factory reset but this should be a last resort as it wipes your phone

I had this problem and fixed it by phoning up my network (EE) asking them to send me their APN settings and it connected fine afterwards

I've heard of multiple people needing their APN settings sent to them after updating, as their phone loses them for some reason. So you might wanna contact your provider and have them send the APN settings again if it's still not working

Was an APN issue, all sorted now. Thanks for all the help guys.

Yeah, the same happened on my sisters phone after she got the update. I used that support tool on T-Mobile's website to re-send the APN and that seems to have fixed it for her.
