Help Internet and MMS services stop working after an hour of restart

[mudricky]

After I upgraded my Sony Xperia S to Android 4.0.4 after an hour or so of not using my phone and/or when I leave a WIFI area I cannot use any data services on my phone from my network without restarting the device. I can reconnect to WIFI again without a problem.

I've tried resetting the phone, checking the power saving settings and reinstalled my network providers MMS and 3G settings.

Any idea guys and thanks in advance.

factory reset it? Sometimes issues happen when upgrading from Gb to ICS without a wipe.

There's quite a few people with the same problem as you over on the sony support forum, have a look here.

Main: No data flows on ICS even though i have a 3G or HSDPA connection
