My fiance and I both got thunderbolts a few months ago. My phone keeps losing the network connection. The 3G icon completely disappears from the status bar but the signal bars remain and have a few bars of signal. If I try to do anything when the phone is like this I get a no network connection error. Mine does this about every 10 minutes for about 5 seconds. i can have my phone laying right beside hers on the table and hers holds solid 3G and mine doesnt.
I have called verizon tech support 2 times about this and the second time they want to open a trouble ticket because they think its an issue with the network. I think I have a bad phone and would just like them to replace it. Anyone else seen this happen and can shed some light on it?
What kind of battery cover do you have? Only reason I ask is that the actual antenna for 3g/4g is on the battery cover itself.
You could get a signal boost if you put aluminum foil in your battery cover, not covering the camera holes of course. The 2 gold connections on the top of your phone in the back are the connectors for the antenna on the back cover. So by putting aluminum foil on the cover you are basically extending the antenna or if you put aluminum on the gold it might bridge a small gap that is preventing conductivity between the antenna and the contacts.
Hope this helps!

Thanks for the link, but I already checked that stuff. I'm really thinking I have a faulty device. My battery cover is the stock one and is on the phone tightly, and I even swapped my battery cover with my fiances. I even tried slightly bending the antenna contacts up so they make better contact and still have the same problem. The last thing I can think of is that I could have a bad sim card. 4G works fine when I'm in a 4G area though. I don't get why verizon thinks it is my line.
I've heard of one other person whos line is bad no matter what phone they use and that's slayers (CM7) wife.

First the bars are for voice so you can lose 3g and still have cell service. 2nd have you tried the app LTE onoff? If you put it on the option for cdma auto prl it should bring the signal in. If that doesn't help I would take it to Verizon.

I lose 3G and 1X both. I can't call or get data when this happens. I still have bars but the 3G/1X icons are non-existent on the status bar. And yeah I have the radio tools option in my wireless settings menu and I have toggled back and forth with no change. My phone is rooted and I've tried several radio combos and also many different roms with the same problem. I have even RUU'd the phone back to 100% stock with the same problem.
I'm almost tempted to go back to my incredible to see if it happens on it. I never had this issue until I got the thunderbolt.
I am on vacation this week and my 3g disappeared in the middle of a hotspot session yesterday. I spent all afternoon flashing, clearing, etc, and my ultimate solution is the one below from android central. I am certain this is a Vzw doing something to the towers in the area as my Xoom, my wife's iPhone, and her iPad2 all kept 3g the entire time.
This should be added to OP.
If the link fails Google "Thunderbolt 3g problems". It will be the first result.

Here is the entire article to give proper credit.
QUOTED FROM ANDROID CENTRAL:
"We'd hoped to give Verizon's network a couple more days to settle before breaking this one on you, but these are drastic times, folks. See, more than a few of you have had issues with getting 3G data on the HTC ThunderBolt when you're in a non-4G area. Nope, doesn't make much sense. But landle in the Android Central Forums has done a nice job explaining how the TB uses the eHPRD 3G network to speed the handoff between 3G and 4G data. Problem is, it ain't working for a lot of people. Good news is there's a fix --no hard resets (which until now had been the recommended fix), human sacrifice or other unpleasantness. Here's what you need to do:
Go to the ThunderBolt's phone dialer. Enter ##778# and hit Send.
You'll get a pop-up labeled EPST, with the choice to "View Mode" or "Edit Mode." You want "Edit Mode."
You'll be asked for a password. It's 000000.
Now flip down to "Modem Settings," and then choose "Rev. A." Change the setting from eHRPD to "Enable," hit OK, then press the Menu button on the phone and tap "Commit Modifications." That's it. You're done.
The phone will reboot (don't worry, you're not losing any data here), and things should, you know, actually work. As landale points out, you'll want to change this setting back once Verizon gets its network sorted out. But in the meantime, enjoy your, erm, new 3G! [Android Central Forums] Thanks, landale!"

Thanks. I saw this article before, but if I do this my phone won't switch to 4G when I go into a 4G area right?
I still don't get why my phone does this an my fiances doesn't. It is 99% likely that we are on the same tower too.
EDIT: Just tried the fix from the article posted above and still having the same problem.
I am sorry to have gotten your hopes up. I should have read closer, I took it that you both had the issue. Plain as day on a reread though.
Had it worked I think your 4G would have been busted.
I added some more details to my issue when I reposted in another thread. Next time you lose 3g try checking for software updates to see if it pulls the 3g back on.

Is the *228 radio update method still valid for the Tbolt? I'm assuming if you were on the phone with Verizon they would have had you do that if it is. But just throwing this out there in case we are just overlooking the obvious.
Also added my question to the post here: http://forum.xda-developers.com/showthread.php?p=15256013#post15256013
@sabbotage
If you are on stock rom & radio, then you either have a bad sim card or a defective phone. Go to verizon & swap sim cards. If you still have problems, exchange the phone.

nope it isn't, Verizon pushed a new PRL to my phone because I was having 4G issues (that was their solution?). didn't fix anything. and my 3G icon disappears once a day for a few seconds.
Just got off chat with Sprint rep admitting there is an outage. My service has gone from 5 bars to "No Service" and back.
I thought it was related to the VM FW I'd installed earlier this week (hoping to fix that ICS VM flash thing) but it appears it's something big.
Anyone else affected?

I am considering leaving but now is not a good time to switch. I would probably go to ATT and the phone i want probably wont be out for about a month. I would kick myself if i had to get a phone that's already been out for 6 months just to have the galaxy s III eat it's lunch a month later. The other option is ATT, which would be more reasonable with the family plan that we need and and they have a solid phone in the One X. The only problem with that though is they do not get good service within my house which is ridiculous (and i'd rather have the evo lte).

Was happening last week here in vacaville Ca. And my over all indoor signal strength is **** now everywhere.
Major issues when I was working in Detroit today. Bars on the phone went from full to nothing to 1 to full to 1, all within a matter of seconds. Data was slow (as usual with sprint) however most of the day my phone couldn't even connect to 3g or 1x. When it did, it was constantly switching from 3g to 1x. Phone calls would go through maybe 1 out of 10 times. I sent texts to about 10 different people today, I just got to the airport and called all of them, NONE of them got a single text from me today, even though my phone reports them as being sent.
So I went to visit the parents and they live in the mountains in a roaming area. I had roaming service for the first day and it went away the next? I tried updating PRL, putting the different corporate PRLs on and the 00002 prl. That didn't work..updated PRL and then tried updating Profile but the profile wouldn't update.
My phone is showing FULL bars with a triangle but no 3g, H or 1x. So I can't call, text, or use the internet. I tried restoring a nand, tried full wipe with a fresh install, tried flipping airplane.mode on and off, tried everything I could possibly think of. Even bought the roam controller app.
So I finally call Sprint and all they said is to pull the battery..tried that and no luck. They said they can't help me if I'm roaming.
I'm really stumped. Think it could just be the towers? I'm here for a week and need service for important calls.
Smart people use googlevoice. NO ONE HAS MY PERSONAL NUMBER. Therefore, as long as I use google voice.... I can re-direct to whatever number I wish. So if out of area. boom. redirect it to the landline. lol. "Sorry mom and dad. I'm stealing your phone for the week." lol. OR YOU CAN BUY ONE OF THOSE devices if they have a good internet connection. then your 3G will work. But then again. as you said you can't use data. so I'm guessing they have no wifi or internet at all. sucks to be you.

Hi everyone, i called sprint today to call about some issues i was having receiving calls and texts while on the sprint network (not roaming) so i called and found i that the towers in my town are in the process of receiving the network vision upgrades so figured i would share the problems i was having so you might know if you are getting them to. that is if you guys get the same problems...
Issues:
1. not receiving calls
2. not receiving texts unless placing a call and only getting the texts while the call is in progress
3. The above being solved by forcing your phone to roam
4. internet might go 1x every once and a while in places where you previously had 3g
p.s. the lady says all this will be fixed once the upgrade is complete
so hope this helps a few people who are getting the upgrade and not knowing it haha
Had this issue and got an Airave. Problem solved, at least at home. It was brutal before that though.

I can vouch for this, it's been terrible for me the past few months. Every other call drops, randomly dropped 3g, data speeds slow enough that I can even stream low quality music. Some parts of the area are great, some parts all you can do is throw the phone into airplane mode so your battery doesn't drain.
That totally explains my evo 3d. For a while when I had it I always had to place a call to get my texts...
as sgt.slaughter said on s4gru they had an article. the jist of it is is that motorola did all the towers in chicago the first time and now samsung is doing them with all different stuff and the messed up combo between sam and moto is messing with everyones phones. they said that it will be fixed eventually...
Yeah same problem here in Hammond, In...right across the border from Chicago's Hegewich neighborhood. Dropped calls, etc...lately though I get full bars and crystal clear calls at work when I used to get 1 bar. 4g eracticly but 3g is horrendous. Hopefully up and running soon

Funny, here we've been experiencing delayed texts/crappy data rates/horrible reception. However, the website doesn't indicate any towers are here are being upgraded. For like 3-4 weeks I could barely even stream something on TuneFM or even a short, low quality YouTube video.

Network issues.
Welcome to Sprint
I really haven't tinkered with much of anything on my phone and I find the most recent OTA to be MUCH MUCH buggier than the previous version. Before the update I never had Sense crash or any other programs crash. Now they happen once or twice a week (sometimes several in a day). Add that to the fact that I am not S-OFF and I have a loathing hatred for this most recent update.

Sorry, but I'm not convinced that my text, roaming and dropped call issues are solely due to the upgrade. You guys can keep screaming that all you want. And I'm not saying that there aren't instances where that's the case. My wife has a shift and isn't experiencing these issues. I've also read about other evo owners with two phones or other sprint phones in their household -- none of which are displaying the same problems.
Again, I'm not saying the network upgrade isn't causing any issues, but it's a bit aggravating to see people post that in every thread containing an issue that can even remotely be attributed to the upgrade like it's gospel.

If you're complaining about SMS issues, missed calls, dropped calls, ect...
Go get your radio tested. It takes 30 minutes at a sprint store. You don't even have to unroot it. Hell, tell them its rooted so they don't mess with the software.
I may try bringing it in tomorrow.

For those not aware...the EVO LTe is set up out of the box to work on LTE and Enhanced CDMA (for lack of better term/knowledge) Also know as Network Vision, or the upgrades.
In cases where an older phone connects and the EVO LTE does, I have confirmed the EVO LTE is connecting to a network type called ehrpd. This network is not yet active in most cities. The older device confirmed to be connected to CDMA and receiving normal 3g.
This is the reasoning behind changing the network mode to cdma only, as many of us have seen that it forces the phone on to CDMA and not ehrpd.
I hhonestly have no idea what I am doing, but this is what I have found in my hours of testing side by side with older devices. From what I can tell every LTE device Sprint carries has this issue, but the other devices appear to lack the ability to switch.
There are also other issues that can contribute to texts and data.
This theory also works in reverse. If I am in an LTE area and on cdma only data and texts are wonky and I have to switch back.
Moral of the story...handoff could be seriously jacked up. I remember Verizon and ATT having similar issues during buildout. You would think someone had figured it out by now.

Dudes Sprint is upgrading 38000 towers its common sense that your going to have some connection issues and aside from that people living in high populated areas if one of the towers goes down for the upgrade the other ones are going to have way more traffic hence your problems......... I'm pretty sure that's right? And also if you if you can make calls and not receive calls or text but still have data your on data only o. O

A lot of the data/sms/call signal issues can be attributed to the current state of network upgrades, though it's obviously impossible to say 100%. In my experience, the network-related things have worked fine from day 1 (July 19th). That said, I have noticed actual system bugs. For example there was a time when I was using Talk (I hardly ever SMS anymore, Talk is way better IMO) and the text in the app became just a jumbled mess of pixels. Took a reboot to fix but it was still weird. And a friend of mine who got his Evo LTE a couple of weeks before me, his phone just started spontaneously overheating all of a sudden yesterday. We suspect a rogue app getting stuck in a loop, but still that's not a good sign; it should have been caught by the OS and at least thrown up a message to kill the offending application. Again, a reboot fixed it but I'm not really keen on that being an actual solution as opposed to a temporary workaround.

In cases where an older phone connects and the EVO LTE does, I have confirmed the EVO LTE is connecting to a network type called ehrpd. This network is not yet active in most cities. The older device confirmed to be connected to CDMA and receiving normal 3g.
This is the reasoning behind changing the network mode to cdma only, as many of us have seen that it forces the phone on to CDMA and not ehrpd.
I hhonestly have no idea what I am doing, but this is what I have found in my hours of testing side by side with older devices. From what I can tell every LTE device Sprint carries has this issue, but the other devices appear to lack the ability to switch.
There are also other issues that can contribute to texts and data.
This theory also works in reverse. If I am in an LTE area and on cdma only data and texts are wonky and I have to switch back.
Moral of the story...handoff could be seriously jacked up. I remember Verizon and ATT having similar issues during buildout. You would think someone had figured it out by now.

This makes the most sense of anything I've ever heard. If sprint would have said cdma2 or something, I wouldn't have had the opinion I did in yesterday's post.

If you want to run your own tests, I use network signal info, open signal maps and an app called "network" to find all of this.
I forward everything I find up the chain of command at Sprint but not sure where it goes or what comes out of it
