Constantly losing data connection
So according to the VM coverage map, where im normally at is pretty much 100% covered. Sometimes at work (metal roofing, concrete walls) i lose signal. This also happens at a friend's house where 3g kinda sucks (even for them on ATT). However whats confusing is that when i lose data and webpages and apps wont load anymore, if i toggle airplane mode (at least once, sometimes more than once) i can get the data connection back. Also, the 3g symbol and the arrows never go away, even when i lose data access the symbol (and activity) remain.
What throws me off is that when i do get the connection back in those locations, i get a decent speed. 600kb/s this last time i got it back. So its not like i have a really weak signal thats getting poor speed/bandwidth. What gives?
currently OC'd to 806mhz stable, Stock VM Rom+ Xionia kernel (revolution red).

If you have anything installed to conserve battery life (or used the dial system to change connection from 3g to 1x), that is likely your issue.
For some reason, once changed, the radio simply isn't reconnecting to 3g when a signal is lost, nor is it kicking down to 1x. Toggling it off then back on resets it.
I had the same thing happen and it was driving me nuts, especially since I had backup the setting and was moving it from rom to rom without knowing. Also, sometimes uninstalling it requires a restart to remove the code, in some cases it requires a wipe, but it seems to be caused by messing with those settings.
All i have is y5 battery saver to toggle my wifi on and off when im in an area of a remembered WiFi connection. However, the locations where this stuff happens (work, mostly) does not have a remembered wifi connection. I dont connect to wifi at work so theres no reason for y5 to mess with my wifi here. At my friend's place where this happens at first his wifi wasnt remembered in my phone and when the connection went down, i switched to his wifi.

I'm having this problem too. Once in a while data connection goes down and the only thing that helps me is toggling data off and back on. Sadly, this has nothing to do with custom ROMs. I had stock ROM for 2 weeks (prior to switching to custom one) and experienced the same behavior.

The data issue was with VM and not the phone I think. I had the same issues last week and called to complain the rep said that they were experiencing data issues with android phones and were working on it. Yesterday i got a text from them to reboot my phone and have not had issues since then.

I don't have a battery saver app on mine. It did this both when the phone was stock and rooted and oc'ed. I haven't gotten any text to rebbot my phone, but I'm sure if they're working on it it'll be done regionally. I had the same problem with the intercept though, so I'm sure its a mess on they're end.

I dont really have much else to add that has not already been said here. I am also experiencing this issue. I was convinced it had something to do with GPS functionality as it would seem to happen with Google Latitude and the Navigation app until it happened when GPS had been disabled on my phone.
This issue has occurred when my phone was stock and also OC'd with a custom ROM. I also have to restart the data connection when this occurs. The phone seems completely oblivious that it has no data connection. 3G icon appears and all. Very frustrating.
On my phone it is very easy to reproduce but I still can't figure any rhyme or reason to it.
Start at my home in San Ramon, Ca. Verify the phone has a data connection.
Set phone on seat of car.
Drive to Frys Electronics in Fremont, Ca. Verify the phone has a data connection. ( it will not )
This occurs going back as well. Every single time.
Restart the data connection via airplane mode or via settings | wireless & network settings | mobile networks | cycle data connection off, then on.
Problem fixed ( until next time )
I did observe one time the phone cycling from 3g to 1x multiple times. It had no data connection while it was doing this This occurred back and forth every few seconds. I cycled the data setting via the method above and it connected to the 3g network and stayed connected. This was in San Leandro, Ca. Not exactly a cell dead area.
I realize this isn't very helpful but it's all I got.
ETA - Phone has no battery save apps what so ever. I get the feeling it has something to do with " handoff " but I am not a expert in these matters. My issue only occurs when traveling.

I for one will never turn 3g off. I need it lol. I went from Verizon to Metro PCS on my Eris. Loved it but after 5 months i was tired of being limited to 1x so i jumped ship because virgin has 3g.
I havnt had any data loss issues yet this last day or two but when i go back to work tomorrow, we'll see what happens.

So far I have nailed down 3 things happening... (yes, I posted this in a few places to help people with the problem, and yes, I experienced all 3)
1. Phone loses activation. This is rare and resetting your connection does not fix it, try the Activate button. I had a bad rom flash do this to me, but others have had it at random.
2. 3g drops due to loss of connection and using an app or setting to increase battery. There is speculation that the menu is labeled wrong on our phones, creating problems. personally, I wiped and got rid of all connection manager type of stuff and leave it stock, it works fine. Fix the other things robbing your battery like Twidroid and Gallery running in the background.
3. The browser.
Dolphin mini has been reported to have connection issues, and I confirmed last night that HD has the same problem. Everything worked on the phone, except for it. I reset data, and it came to life. Do NOT use Dolphin to check for connectivity. If it's your default browser, change the home page to a more reliable site like Google or Yahoo, it may help at least some.

I swear i put a reply to this thread earlier today... this happens on both my S and V optimus. with stock and custom ROMs. I don't think its network issues I think its sprint persecuting heavy data use phones. (I.E. Android) I'd like to know if black berry users are experiencing these same issues.

I've had similar intermittent but frequent loss of data connectivity on the Optimus V.
I'm running aosp CyanogenMod 7 (gingerbread).
I stumbled on an apparent fix for this particular ROM, at least:
Under "Settings/Wireless & Network Settings/Mobile Networks", make sure "National Data Roaming" is enabled and under "System Select", choose "Home Only".
With these settings, 3G has now been solid for me for the last 2-3 days

they do. I have a sprint Optimus S and it doesn't do it quite as often but it dose happen. I'm thinking sprint is giving priority to contract users. I'd be willing to pay an extra 10$ a month to ensure my data doesn't mess up..its very annoying. but it seems to happen the most to me when I'm trying to dl larger files. they have to be throttling the bandwidth and their system just messes up and cuts the connection.
I'm starting to fear there is no fix short of sprint upgrading the network to handle more users.
