Tips on avoiding "Could not activate cellular data network" with New iPad So I bought a new iPad, 64GB + 4G. And since then it seems like every time I pick it up and go to use a network feature (Hero Academy, Tweetbot, Safari etc.) I get this message "Could not activate cellular data network".

If I reset it then everything will work OK until after I put it away for a while. There's no definite time period for the network failing but it always seems to happen after I have been home or at work (inside a WiFi coverage area) and then I go to use 3G again. The fact that it does work fine after a reset says to me that this is not a signal strength issue, this happens repeatedly at the train station and will always work right after reset. Before reset the network indicator shows full bars and 3G indicator.

Has anyone else experienced this and improved this by changing anything in Settings, by talking to their carrier or anything else? I am thinking this has to be an iOS bug. I should not have to do a white apple reset to use network services!

If it matters I am using a prepaid Optus 3G sim in Melbourne, Australia. My only APN setting is the APN field which is "connectme", correct according to the Optus guide I got with my sim. (new iPad cannot use the 4G networks available in Australia: Australian Competition &amp; Consumer Commission)
I have had exactly the same issues with my New Ipad 16Gb 4G.
The only way I have found that really gets round it, is to manually select the Network provider, insteady of leaving it set to the 'Automatic' setting.
Come on Optus sort this out !!
