I have a Sony Xperia U. I had some problems with 2G/3G data connection when I bought it. After some configuration, power off/power, removing and reinserting SIM, things went all right.

Now I've updated the OS and I have the same problem. I've set the APN, then activated the data connection, but I do not see the H/E/G symbol to tell that the data connection is active. I've verified, and have the data traffic for my subscription.

  • How can I verify if the APN configuration is good? If there is an APN problem will I have the described behaviour?

  • Is there some way to do some more troubleshooting? I read logs (with aLog) but didn't find anything?

  • Is there any configuration/procedure to fix the problem?

Some update:

Network operator is French SFR (sometimes disappointing I must say).

So I managed to take a look at logs (using adb).

Main log:

Maybe the problem is PDP Context Activation Failed ?

My service provider has three APNs. One for MMS, another for their own portal access called 'live' and the third for Internet access. Only if the third is selected I am able to connect to Internet. I am not sure why, sometimes my default APN is set to 'live' on start up and it results in breaking my head about the same problem. I accidentally found this and I had to manually switch to the third APN to make Internet to work. Check whether you have this problem. –  Narayanan Aug 6 '12 at 13:23
    
@Narayana123@123.com There is only on internet connection APN and one MMS APN, but the MMS one can't be selected (this is normal I guess). –  Paolo Aug 6 '12 at 14:05

Turns out the problem was actually wrong APN configuration. I configured the device using netowork operator automatic config mechanism, but turns out the parameters sent by the operator itself were wrong. Phone call to customer care solved the issue.
