For the past week or so, I've been having issues where I will drop to 1X in places where I would usually get a steady 3G signal. I'll have two bars (-85 dB), and show 3G, but when I actually go to use the data connection it drops to 0 bars and switches over to 1X. If I stop accessing data for a brief period it will return to normal.
Does anyone have any ideas? I had been using the 11.19 radio, but flashed back to 9.01 and saw no improvement. I've done the "update roaming capabilities" a few times, and every time after I've flashed a radio. I'm running CM7.0.3. I'd appreciate any suggestions. Thanks.

I was having data issues like yours in cm7.0.3. I don't think your alone in this situation. Other people have had trouble with this as well. I don't think its a radio problem because I swapped radios with the same results each time. I would roll back to an earlier cm release and wait for the next update. That's what I'm doing.
Ah, I didn't think the ROM really had anything to do with reception. Glad I checked, thanks.

Well, I just flashed OMFGB and I'm experiencing the same problem. Is it a known issue in OMFGB 1.2 as well?
EDIT: I just flashed back to CM 7.0.2.1 and I have the same issue. I guess it's either my phone or Verizon.

i started having this issue recently on miui 4.29 and it persisted onto 5.6. started happening after updating radio to 4.08 but i haven't been bothered enough to try changing back to an older radio.
I think it may just be Verizon. I have the same issue from time to time on SR 4.0 rom, with the stock radio.
Yeah I'm pretty sure its an issue with Verizon, roms really shouldn't effect your service and they never have with me.

I'm not rooted and on stock and i'm having the same issue. Def verizon.

Me too...
It's been happening with stock, Redemption, and now with Sky Raider.
I flashed the new 04.08 radio and everything worked great. Just about a week ago I started having the same issue. Flashed back to 11.19 and stock 07.28 and having the same issues. At this point I'm thinking it's a VZW issue, very possibly them getting their 4G towers in place.
Alright, I'll hope it comes back.
For a few months I've been having some GPS accuracy problems, and I was wondering if the two were related. GPS test will show 20 ft accuracy, but it will be showing me on a street 100 ft away.

I was wondering if anyone else has/had this problem. My evo tends to time out on 3g, especially when I download a rom. The 3g indicator just goes dark and will stay that way for a couple minutes. It wouldn't be a big problem but I don't have hi speed where I live so every Rom I download is through my phone internet. When the 3g times out it causes the Rom download to fail. Has anyone else had this problem and what can you do to fix it? It's irritating having to download a rom 5 plus times

This only happened to me when I was on stock. Now that I'm on a custom ROM, it doesn't happen anymore. I notice you are on a custom rom, so I'm sure that's not the problem.
It may be a coverage problem. It also happens to me when I'm switching from 3g to 1X, so that may be it.
The area I'm in has almost full signal. I've actually experienced this more on custom roms then when i was on stock.

My 3g does not work on roms outside of stock sense roms. I've read where others says sense roms always show 3g even if you are getting a 1x signal but my wife has an evo 4g, unrooted, as well and my 1x is way slower then her 3g signal. I 1x signal won't load web pages in most cases. I downloaded the most recent OTA and then flashed a rom after words but still no 3g.
Any update on this? Just was curious if this did the trick for you.
After I flashed the new radios etc. I tried to download a rom overnight. When I got up it said download failed, then I remembered to update prl and what not. After i updated things were ok until I tried out my 4G. I was having major issues with it not downloading. It was extremely slow. I was using the shooter ROM when these problems started so I flashed another ROM and haven't had any problems so far. Is it possible for a rom to affect 3g and 4G performance?

This isn't necessarily true. Most custom ROMs show 1x. However the stock does not. Also, 1x should be slower than 3g.

Sorry if I wasn't clear but that was my point. Thats what most people "say" about roms showing 1x and my 1x is slower then my wife 3g so I know its not that we don't have 3g in our area, its the rom. Right now I'm using R2R-green-R3, which has a 4g LTE icon and faster then the 1x rom I was using before. I flashed the honeycomb theme over it looks great and works great!

It shouldn't be the rom causing you to get 1x, have you tried updating prl/profile? I've run multiple custom roms and never had a problem. Areas where I know get 1x show it, but areas that get 3g show 3g and have 3g speeds
Sent from my PC36100 using xda premium
I did up date the prl/profile but still no 3g. I'm at 3g speed now so its not a problem. Maybe I did something wrong on the other rom?

Sometimes my phone, even when there definitely is signal, would say searching for signal. It would take a couple reboots before I get my signal back. Even tried manual registration, it would get stuck registering on the tmobile network. Im running darkside v8, could anyone help with this annoying issue?
Flash another radio?

For Darkside ICS roms, you need to use their modded radios, if you don't flash theirs, you will get data and signal issues. Check their thread for downloads.
I tried this , still didn't help. I switched to cm9 and installed the recommended uvle1 radio , and I still had the same problem. Either I had to manually register on T-Mobile or keep rebooting until signal came back (I'm in a full signal area)

A strange update on this thread, my problems with signal loss are now gone now that I'm on cm10
Edit: when it boots I have to make sure its 2g/3g setting otherwise it boots with no signal
Sent from my SAMSUNG-SGH-T989 using Tapatalk 2
Disregard what I said in my previous post, I'm really hoping for a real solution/possible flaw with my gs2. I had to move my sim in my sidekick 4g, because my gs2 didn't seem to pick up any signal, and registering on the network would take forever . This is the biggest problem I have with my gs2. I can't always be moving my sim to the sk4g everytim my gs2 doesn't want to pick up signal, its very inconvenient. If it helps at all, I've had this issue every since I've gone beyond gb (this only seems to happen in ics and jb)

I am running the latest cm10 nightly and I haven't been able to connect to 4g lte for the last week or two. Is anyone else having this problem? Has anyone found a solution?

Which market are you in? There's a chance that the tower was only on for testing and has since been turned off. There's also a chance that another tower closer to you is currently being upgraded, so the phone is trying to connect to that tower's LTE, getting rejected, and falling back to 3G. That's what's happening to me, and it's frustrating because I had a steady 4G signal for a week and a half, then one day, it refused to stay connected to 4G for longer than a minute. Now, I just have to wait for them to finish the new tower.
The reason could be just about anything depending on your market.
I am in the Atlanta market which has been officially announced. Friends that live nearby have not been having this problem on stock ux software. I was wondering if cm10 has a big or something?

Actually, it has a couple LTE bugs. CM10 doesn't currently handle 3G/4G handoffs properly, so that could be part of the issue, but it holds a 4G connection fine if the signal is strong enough, at least from my experience. Another bug is that it will just stop making connections, and you have to wipe data to fix it. Have you tried toggling airplane mode? If that doesn't work, make a nandroid and try a clean install of CM10. I had to do that recently because it completely stopped connecting to 4G and barely connected to 3G. As soon as I booted up, 4G was back (didn't last long, but I explained that in my other post). If wiping data doesn't work, flash to TW and see if the problem persists. If it still doesn't connect, then you may have a hardware issue, but I think that's unlikely since it was working for you before. You never know, though.
Keep in mind, even though Atlanta's been officially launched, it's only about one third complete, so lots of towers are still being upgraded. It's possible you're facing the second issue in my first post, like I am. If so, then just concentrate on how much better it'll be when the new tower is finished.

Happened to me several times. The best thing you can do is make a nandroid once you get your favorite AOSP rom set up to your liking, and restore to it once LTE stops working. I tried to get myself to go to TW but its just so slow
What is TW?

I have a similar issue. If i go into settings, about phone, and status I pick up LTE:13, but I get no connection or IP address so I have to change over to 3g. Is this a known issue, and if so is it being addressed? I am currently running nightly 10-14-2012 if it helps. Thanks
Edit: I've tried TW and it works just fine there. 14 down and 6 up.
Its likely to do with cm10. And the handoff issue like it was explained a few posts back. I love cm10 but data would work if u was lucky for 2 hours out of the whole day. So I'm on the leaked lih build. Just gotta wait patiently for the great devs to figure it out.

CM10/PA here, my GS3 will randomly lose all data connection whenever it feels like it! It will go from full blue bars with the 3G icon to full bars grey'd out and back even if I'm stationary!
Tried flashing 2 different radios with no avail. Any advice? My phone didn't used to do this, but I'm not sure what I changed!
I'm gonna try a different kernel, I'll update this if it worked. Thanks!
Just tried a different radio, no change

Then perhaps it's got something to do with the infrastructure updating. I'm about 30 miles out from Chicago in the burbs and my daily commute moves me 20 miles away from home but still 20-30 miles away from the city, so maybe it has something to do with that.
I'm about 45 miles out from Chicago in the burbs. But traveled all over today. No change where ever I went.

I'm also experiencing this in DC area. I just bought Sprint GS3 about a week ago, and just flashed last night after using rooted stock rom during my normal commute ~60 miles round trip. Normal commute with stock rom seemed to play Pandora with no drops, today (first day using CM10), 3g dropped so many times i gave up and just listened to music i have on my phone.
Any updates, or ideas? I haven't tried flashing radios yet, but it seems from other posts above, that doesn't affect anything?
I'm running CM 10.0.0-d2spr Stable, same kernel that came with CM10, the only thing out of the ordinary I have set is underclocking, 384-810 Mhz, but that shouldn't affect anything...

I live in the middle of Atlanta and I have the same thing running cm10 stable. I don't remember having this problem before Jelly Bean has anyone tried reflashing ICS
I have suddenly been having problems with my 3g. I look at the symbol in the status bar and it will upload but it will not download. It's almost like the code is stuck in a loop. It will randomly start to work again for awhile and then act up later. I have wiped dalvik, cache, and I even reflashed my ROM (FREE GS3). I updated profile and PRL. That was even a problem because I would get an error since it wouldn't download. Before I flash back to stock and call sprint, does anybody have any ideas? One other note. I have driven through LTE areas and both downloads and uploads work with no problem.

Try updating PRL and Profile then restart the phone? That may help, I mean if it does then you just saved like an hour of resetting and restoring. If it doesn't then you just wasted maybe 2 minutes.

I called Sprint and they couldn't fix it. I switched the network mode to CDMA from CDMA/LTE and it worked flawlessly. I don't know what that means but something told me my LTE and 3G weren't playing nicely. Whenever I go through a 4G area, it works to perfection. Then I get back in a 3G area and back to the same old thing.
I forgot to mention I flashed to stock unrooted and it seemed to function better but the problem still existed.

I have the same problem I have no idea what to do. I have a custom ROM the only way I get it to work is when I toggle Data on and off really fast. I didn't try the CDMA only though. Either way it's no excuse why our phone's are acting like this.
There was a DATA_HANDOFF.ZIP floating around somewhere....it was made for AOSP but if you make a backup and flash it, it might do some good
I had the same problem. In your phone key pad enter ##72786#. Its going to do hands free activation, prl update, profile update, firmware update (at that point you can cancel)
