Help cannot connect to internet error at times

[kiddk1]

sometimes I will be trying to access the web and I get this error I then check my settings to find that mobile 3g data is disconnected. any suggestions as to what could be causing this.

Several possibilities come to mind:

• You're at a lull, perhaps a fringe-y kind of area - this might be helped by Mobile Data always on, might not
• You're near a tower and there's no call for this - in this case, the Evo forum has a thread noting that you can open a trouble ticket with Sprint, but they're likely to take no action unless some threshold of complaints is reached, presently thought to be 50 customers
• It's literally a stuck bit on the motherboard, typically cured by a battery pull for about 60 seconds
• A piece of your settings have lost their mind - update PRL then Profile in that order, it can't hurt - if PRL rev number doesn't change, but behavior does, don't sweat the technique, it's just correcting a corrupted internal file

Suggest you see if this will help you find nearest towers - https://market.android.com/details?id=com.technolatry.antennas&feature=search_result

I've found the app slightly skittish, sometimes getting the right tower locations right off, other instances needing a little time to be sure
