So... About 4 days ago, I noticed that I couldn't connect to 4G anymore, but 3G works fine. Now I've always had full signal 4G where I live because there's a tower just down the block by the Sprint store. I can connect and I even get an I.P. address, but there's no data getting through. You can imagine how many times I went to recovery, cleared data, wiped, re-flashed, all the while thinking it was the ROM that had problems.
The answer came to me in the form of my younger brother. He has the Evo Shift and also had been having issues with his 4G. Now his phone is stock, so that ruled out the ROM being the issue (thank GOD I thought I somehow screwed my WiMax). So he tells me there was a power outage about 4 days ago at around 3am, since then he hasn't been able to connect.
What I'm thinking is- IT'S BEEN 4 DAYS... You guys here who work at Sprint, do you think a small power outage can bork the 4G network for 4 days?
And if so, how come it hasn't affected the 3G network as well?
Maybe It's another issue altogether...
Sprint actually has 4G?

4G is WiMax and 3G is EVDO so one getting knocked out might not affect the other....also, if they haven't had reports about that particular tower, they might not know to fix it.
To the poster above: if your not going to be helpful, don't post.

That sucks man. I'm blanketed in supposedly 4g service and can't get it neither. I wanna go take a dump on one of their towers.
Can a power outage kill 4G? Certainly. Cell towers work like many other electronic devices, and are still prone to things getting shorted (Even if there are several layers of protection to try and stop that). I would honestly recommend calling tech about it and seeing if the towers near you have any posted outages, or at least report the issue.
They likely cannot fix the issue unless they know about it, and if everyone presumes everyone else will report the issue; it may never get reported.

I'll call tomorrow and bother someone over at the local sprint. I'm just wondering how did the 4G go out and not the 3G network. Oddly enough I also noticed the 3G network is slightly faster now... i.e. - I could never watch HD movies on Youtube without having the 4G on, now since of course I can't connect I tried on 3G and it didn't skip a beat. Maybe breathing too much spray paint fumes is making me crazy
The 4G sits on a separate tower from the Sprint tower's as the 4G is provided via Clear.

I've made references to this in Q&A, so apologies if you've read this already.
Simply put, my mobile data does not work on this phone. What I'm finding is if I leave a WiFi network or go to/from Sprint to roaming data, the hand-off to cellular data never happens as one of three things invariably occurs:
a) Mobile Data is stuck in 'turning on...' and thus I have no signal at all;
b) I have signal but no throughput (the up/down arrows never light up and I get no data connection);
c) the phone just reboots.
So basically if I change my network state, I can't go back until I reboot. Toggling Mobile Data does nothing in any of these instances. Now I expect holes in the software during a device release, but not holes you can drive a truck through. If anyone is experiencing the same issue or has any ideas, I'd love to hear them. If it's not solved by the end of my 14-day rescission period, this thing is done for.
I had this same exact problem. Update your profile and PRL. That fixed it for me but I dunno if that will fix the problem permanently. Might be a hardware defect but I hope it was just a prl/profile issue.

I've tried updating my profile and PRL and unfortunately that did nothing, and moments ago I gave up and called Customer Care to reactivate my OG EVO.
Of course, 30 seconds after that was all done the representative told me there's an EVDO data issue/outage that has been persistent in Philadelphia since the 22nd. You'd think they'd tell their store reps this valuable information, but such is not the case. I'm going to try running some tests on my OG EVO for comparison's sake and see how much truth they're telling me before I put the LTE back in the box and tell Sprint where they can shove it.
I have noticed some quirkyness with the WiFi/3g handoff on the phone on stock and viperROM. I am in the Philly market too, possibly the issue.
Sent from my EVO using Tapatalk 2
It's becoming unbearable. I lose my 3g connection about 3 times a day. But today, it's lost it about 20 times and that's no exaggeration. It's lost mobile data at least 5 times in the last hour. HTC has got to do something about this.

So I reactivated my OG EVO and sure enough, 3G data speeds are nothing short of awful in the 19103 area (~6KB/sec on average), compared to the 19106 area a mile or so away -- there's definitely an EVDO issue in the area. However, the OG EVO is not exhibiting the same WiFi/roaming hand-off issues that the EVO LTE is; that has to be a software issue specific to the phone. Seeing as I frequently walk in and out of various WiFi blankets throughout the city several times every day, this bug is a deal-breaker for me.
When I leave a wifi area I've noticed it takes a very long time to pick up 3G. It was nearly instant on my E4GT.
I just had the same issue with my mobile connection. Updating my profile and PRL seemed to do the trick. Changing from wi-fi to mobile also takes over a minute...
change your phone from cdma/lte mode to cdma mode, did the trick for a few friends of mine.
I've also been having the same issues. My phone will just drop 3G and go to roaming or no signal at all constantly. I also live in the Philly area so I'm hoping since we're in the second wave to get LTE that its just Sprint working on the network but I'm starting to suspect that we have a serious problem with our phones. Im on my second phone & a few different ROMS including stock & I've been having the problem since pre relase while my wife's Samsung E4GT has had no issues.
Edit
Well I took the advice from another thread and switched from CDMA/LTE to CDMA only & I haven't had any issues with my 3G dropping or with the WiFi to 3G handoff. Don't know if that fixed the problem or if Sprint just isn't working on the towers today.

Okay this is starting to piss me off. I loose 3G service anytime I unlock the phone. In my house I can not keep a call connected to save my life, even though I have 4 bars. My 3G just looses signal. Its not when I switch from WiFi. It just does it on its own.
The first thing I tried was to turn the CDMA/LTE to just CDMA, tested this for 2 days nothing. I updated both Profile and PRL.... nothing.
I am really tempted to walk into a Sprint store and through down because this is unacceptable. And this happened to my first EVO LTE, so I returned it within my 14 days, got a second one and its doing the same thing. I thought well maybe its because I am in the Chicago Subbards but I have been in 2 other states and I have the same issue.
Anyone know of a fix or when HTC will actually fix their newest phone? I mean come on really guys, how is this okay?
EDIT:
Also, I tried turning off NFC and that doesn't help either.
And is anyone else's EVO get REALLY hot?

As of today, dead. Voice is ok. 3G is gone. (Philly)
Im in lexington sc and for about a week now my data (which i had inside my house just fine) has been out almost completely and i have called 3 times and got 3 different reasons on why this is. Now last night they tell me that there is NO eta on when it will return????? WTF! This better be a LTE thing. If not this is getting out of control fast... They said id be credited for the outage, well data is 50% of what we pay for. This is unacceptable sprint...
Say if it is a software issue shouldn't most people have this issue ?
Sent from my EVO using xda premium
probably, depending on which software/firmware version you're running. I think it's more specifically related to the radio version/fw vs the towers causing it. it seems more and more like i get varied results depending on where i'm at. always the same end result, just the behavior in how long 3g stays connected varies.
I have been dealling with the same issues. I was driving and my data went out. Can't get data only if I connect to a WiFi, I tried everything. I am on the latest firmware, prl, ect. I got it back yesterday about 5 hours later but as soon as I go to an area with no service it will not come back. (Voice and text work fine) I am still without data since Noon today. I know I have 3G because my old Epic 4G is working fine. I even flashed the radio again and flashed the whole firmware again. Still doesn't work. I am about to take it back and get the Samsung....
My data signal on HTC EVO 4G LTE keeps dropping on and off. It doesnt matter if I am on CDMA or CDMA/LTE mode. I am located in Overland Park, KS and the 4g coverage is spotty here.
I opened a network ticket with the Technical support team. He checked my location, outages etc and concluded that it wasn't a network issue.
Then I found two more threads on cummunity.sprint.com with similar issues. I cant post URLs here due to newbie status, but if you search for 3g connectivity issues for HTC EVO, you will find them.
Per the threads, its not a device issue (swapped devices have the same issue). The OTA update that came out a few days before didn't fix it. A customer service rep also did a software reset of my phone, which didn't help either. So if its not network or hardware, then it has to be the software.
It very well could be that the HTC sense s/w has a faulty wake call for the data radio. Apparently, the 3G radio will be shut off after some time to save battery. The sleep or wake functionality in the HTC Sense for the 3G radio seems faulty.
Is there a workaround for this issue?
Install Mobile Signal Widget Pro.
I have it on mine and my device will show 3G but its stuck on 1x or the widget will show an exclimation point. Which is a data connection error.
I am in Dallas, an active LTE area. But LTE is spotty where i am at. I have noticed that if my device tries to connect to LTE it has problems going back to 3G.
Right now i am stuck with CDMA ONLY due to this bug. But i have still seen it happen a time or two, but less then when i had CDMA/LTE..
Also the only way to fix the data issue is by powering off my phone and turning it back on.
Hope this helps. I believe its a HTC / Sprint LTE bug that does need to get fixed.
Im jumping ship shortly to the GS3 if they dont resolve this.
I'm in Overland park as well. I had 4g on the 15th, although very slow and only outside. And now that isn't available. And the 3g is spotty. Always turning on and off.
It's the towers regardless of what they say.
I frequent an area that gets horrible 3g coverage despite what the spring map says. Sprint reps have given me every possible amount of BS as far as explanations. Yesterday, I turned on data roaming and after about 3 minutes, tapatalk finally loaded. Then another 3 min for a thread ro load, etc. After about 10, I had almost a 20% battery drain and my phone was about to overheat. I heard that while roaming on Verizon towers, we're only getting 1X. Is this true?

Its this phone for sure. I came from the Evo 3D and never had issues. The first day heading to work on this phone i noticed my 3g which always worked the entire ride and while at work, was spotty with this phone. I barely get 3g in work now. Pretty annoying. I'm using the new radios that came in the update and no change.
I had the same issue until I flashed xHausx's deodexed ROM, which includes the latest OTA fixes. That mitigated my issues, and the free Sprint AIRAVE they sent when I complained enough helped out considerably.

Happens to me!
If I turn on airplane mode and turn it back off the problem clears and goes back to 4g or 3g speeds.
I started experiencing this problem last night and I've yet to iron it out. I've tried several things. Looking forward to a fix. Going back to the OG or the 3VO in the meantime.
Edit: For those of you still experiencing this issue (FOLLOW THE LINK IN THE POST BELOW); as well as, those of you that encounter this ... I was able to get things back to normal w/resetting the device back to factory through ##72786#. After going through the activation process (or manually reprogramming your device) you should be back on track. Hopefully someone finds this helpful.

Something similar to this worked when I was having issues with data not turning on at all when on lte/cdma. But the issue we're seeing in kansas city here is just due to the work they're doing. It's just on n off all the time on 3g. And places where I had 4g, no longer do. The 4g I had was only pulling 1.5 down, so I think that's getting bumped up to what it should be.
I'm getting these data drops as well. I'm in Gaithersburg, MD. It was just announced that lte will be in Baltimore next month, maybe they are working on the network? I might swap this one for another but it might just happen again?
I had to reset my phone 7 times today to get data back.
Phone would drop from 4g to slooooow 3g, I turn on airplane mode and turn it right back off and BAM, 4g is back.
This is definitely a phone issue!
It's not a phone issue.. Notice how all of us seeing this are all in first run LTE areas. KC, Baltimore, Texas. We're all supposed to have 4g but don't, and the network is kicking on and off. swapping out for a new phone will not help.
It's the network, not your phone.
Curious issue with my Titan II. Cellular data connection just fails at random intervals. Cycling airplane mode or rebooting the phone is the only way to get it back. HTC blames it on AT&T and AT&T blames it on HTC. I've spent hours on the phone with each. Even got a new Titan II from AT&T, but it went into this constant reboot loop, so I went back to the first unit.
Now comes the interesting part: I live in Detroit and have been traveling to FL quite a bit, this year.. and the issue DOES NOT HAPPEN IN TAMPA. Phone runs perfectly well, there. Here in Detroit, cellular data "up" time ranges from 5 minutes to 14 hours when static. 2 minutes to 20 minutes when driving around town. Drops are less frequent when streaming something.
HTC Titan II stock (FW: 2180.0400.118011.502)
Windows Phone 7.5 (7.10.8112.7)
4G SIM card (3rd one)
Appropriate data plan
Serious thanks for any ideas anyone has. Do I add an APN, throw the phone against the wall, or what? Please do not suggest I change to a different phone as that is not an option.

It seems something related to wifi sleeping when the phone goes stand by and the solution could be keeping it alive in some way....like streaming..

Are you sure you aren't hitting "black spots" on your network? If you have random connection drops in only particular area it is likely the masts and AT&T issue. I've swapped my provider from the one which did 2G/3G signals to 3G only provider. 3G only has better coverage and lesser black spots on the network and hence I hardly see any drops in connectivity. Don't hard reset or anything, it will only make you re-do the whole phone, won't help the cause.
Have you checked if two golden pins on the back cover are making good contact with phone?

Have to rule all of that out as it doesn't happen at all in Tampa. I can drive from Ybor City to Clearwater and back and never need to reset the phone. Here at home, I have four bars and will lose cellular data with the phone in a static location. Driving around in Detroit is guaranteed to make it drop cellular data even with the phone lit up and active. I can have Navigator running and it'll just quit loading maps and giving directions until I cycle Airplane Mode. In Tampa, this doesn't happen.
In Tampa, I've gone the whole week without any need to reset the phone. I can't walk from the gate to baggage claim in Detroit before it loses its data connection.

UPDATE: Cellular data connection is a little better with WiFi turned off. It won't lose it as quickly in a static location, but still loses it as I move between towers. Also had to reinstall a couple of apps that had stopped launching.
Is forcing Tango an option?
I have the same problem,
I live north of detroit.
my phone has been in to htc repair 3 times, i think they have replaced every part in it, the last time i got it back it held connectivity for 11 minutes.
this is on my home tower as well as several towers around me.
Normally all testing was done with wifi off, on towers where the lumia 900 and my wifes iphone have never lost data.
i have been waiting a week for a htc level 2 rep to call me.
we shall see
Keep me posted. Last time I spent time with HTC, they decided that - since the issue only happens in Detroit - that it was AT&T's problem. AT&T, naturally, claims that the problem doesn't appear on any other device, so it must be the device.
Can't wait for Windows 8 phones. I'm getting one.. ANY one.. the first day they go on sale.
Well I just got off of the phone with a level 2 rep from HTC, who seemed pretty confident that the problem is the rear cover. He is sending one out, and says if that doesn't fix it then it will be a phone replacement.

So, I'm in Florida for the week and noticed something.
In Detroit, the status bar says "4G"
In Tampa, the status bar says "LTE"
As before, I have not lost cellular data connection since I landed in FL. Kind of rules out the battery cover as the issue is gone, here. It appears the issue goes away in LTE areas while it's present in areas yet to get LTE. Detroit's LTE rollout hasn't happened, yet. So, it appears I've got another month of suffering before the problem is rectified.
One other note. With Internet Sharing set to ON...
In Detroit, my wife's laptop connects to the phone and can get internet.
In Tampa, my wife's laptop connects to the phone, but cannot get internet. It gets the error msg: "your computer is trying to use a dns server that is incorrect or doesn't exist"
My laptop works flawlessly connecting to the phone's Internet Sharing both in Detroit and Tampa. For the life of me, I can't find anything different in her settings over mine. Both are Win7. Hers upgraded from Vista, mine x64 and new this fall. Also, two internet-capable televisions connect to the phone and get to the internet flawlessly. But something with LTE doesn't like my wife's computer. Odd.
Honestly, I adore everything about this phone except for the data connection issue in Detroit (and a few other areas, it seems).
There HAS to be a setting or SOMEthing I can tweak to get this thing to work in Detroit.
Check battery cover, radio negotiation, firmware of radio

Hum.. that's curious. I had the original titan with similar issues.
I disabled wifi when not connected. I replaced battery cover also. The titan2 supposedly fixed that issue with the battery cover because it was a design flaw.
The radio supports 2G, 3G/4G/H and LTE. You may want to check it. You can set the radio it uses and not let the firmware decide which radio to use. You can check the service menu, I forgot the code. Just search for it.
If you use 2G, data and voice are not supported simultaneously. Check and make sure the contacts on the battery cover and on the phone are clear of debris. Use a solution to clean the contacts on the phone.
In the past I manually set the radio to 3G (HSPA and HSPA+) [HTC Pure, HTC HD2 on at&t]. The 3G radio is mature and should have less issues with the radio negotiation.
BTW, there is a keep alive wifi app also.
Thanks. I'll have to look for the codes. It's pretty obvious after going back and forth so much that the Titan II has a flaw with the way it handles AT&T's 4G. Scanning the maps from others who have had problems all show that they're in areas with 4G but without LTE.
Yeah, if I could force this thing to do LTE or 3G I think we'd be fine. It's the Best Phone Ever so long as it gets LTE, 3G or Edge. Anything else and it's crap.
Yes, back connector is okay and I've done this every way one can think of and kept notes. WiFi doesn't matter. On or off, the T2 will lose cellular data connection randomly in 4G areas. NOT in LTE areas. I'm only unable to test it on other carriers.
Similar problem with data
So I have had a similar problem -
I had a Samsung Focus, great phone, but I wore out the USB port - wouldn't charge consistently or sync. I figured I might as well use the insurance I had been paying. They sent me a Titan I - it had the bad microphone issue. So after some messing around they sent me a Titan II.
It has never had consistent data connection. I am in an area where I get the 4G icon (not LTE).
My experience tells me that if I move around and change cell, or lose signal in the cell I am in for any reason, then the phone will NOT connect back to data. It can (almost always) still get phone calls and send/receive texts and so on, but no data. Toggle airplane mode always fixes the problem, until the next time.
Originally HTC wanted to send me a new back cover - AT&T have been completely useless, they have no idea. Eventually after messing around with factory resets, powering on and off continuously, another new SIM card, HTC decided they want the phone repaired or replaced (level 2).
It is still inside the 30 day limit for exchanges from Assurion (AT&Ts insurance carrier) so it's getting replaced. I'll let you know if it fixes the issue, but I haven't been in an LTE area so I can't check that.
Personally I think it is a problem with handing off/reconnecting to 4G tower service - we'll see......
Anyone have the radio codes?
I've had the same problem since I got the device as well; but have noticed that it doesn't happen in all areas around me. My house is one of those areas though that I always lose connections. I've tried every APN / idea I've found on the internet with no luck. It's clearly something to do with AT&T towers. The only think I've not been able to try is a different SIM card in the same phone since it requires a '4G' sim card to even work at all. However the same SIM does work fine in '3G' only phones.
Going with the radio idea, does anyone have the codes to turn off the LTE radio? I just saw the list saying this phone will be long gone before AT&T ever gets LTE in Colorado so maybe just turning it off would help. Every code i found was for the T1 though and it didn't work on my phone.

I'm more skeptical than you, trust me, but it would explain how so many people get the same problem with replacement handsets, as that piece is often not replaced

UPDATE: HTC insisted on sending me a new SIM card cover (since it contains the radio's antenna). Despite my argument that the fact it works in Florida negates antenna as a suspect, they sent it along, anyhow. Naturally, there is no change. It still randomly drops cellular data. And now, I've picked up another spot on the freeway where my calls get dropped. Granted, it happened ONCE, so that could be any number of things. Long story short, it's not the antenna.
Next idea?
Well, I'm in Florida and found a spot where the phone fell back to 4G from LTE. Data issue returned. So, that takes geography out of the equation. The phone can't hold a data connection when using 4G. So, should I go for a fourth unit?
My addition:
AT&T recently rolled out LTE to my area in CT. I never had the problem before on straight 4G. Now, when I go from LTE to 4G (my drive every morning) data just stops working. I push it in to airplane mode and back out again and it works.
BTW - I am running Tango, so that is not likely to be a fix unless a radio update is released with it.

AT&T just switched on LTE metro-wide, last night. Now, the Titan 2 performs just as it does when I'm in Florida. It's nice having a data connection that'll stay good all over town, again.
I have spent some time discussing this with HTC and AT&T. Actually just got off the phone with HTC level 2.
I too have gone through all the options - new phone, new cover, new SIM card (you can just go into AT&T and ask for one, no charge), hard reset, everything.
From the information in this thread, and elsewhere I can say that the phone drops data on one of two things happening:-
- connection to tower is interrupted in current cell, but is re-acquired
- connection is handed off to adjacent tower as you travel to a new cell
Both these things will drop data IN 4G AREAS ONLY. If you are lucky enough to have consistent LTE in your area, you shouldn't have any problems.
Right now I'm working on getting the service menu codes so we can play with the radio settings. It sounds like HTC support reps have been forbidden to give these to end users on windows phone devices (I wonder why??!!).
If I get this information and it provides a fix for this issue, I will (obviously) post it, and I imagine HTC will as well. Here's hoping.....

Hi I used to have the S3, obviously I have the Note2, I notice that the location of work in nyc area had constant 4G all day. Now it bounces 3G most of the time. So what I did it checked mobile networks from global to LTE..
Is that right or should I leave it to global. When on global it searches for a better signal all the time. Maybe my sim card is bad??
Are there any issues with the radio, baseband, software issues?
Maybe my phone has an issue with the antenna?
I actually in fact live in NYC as well (downtown manhattan to be specific) and in my area, when i start to drive out, I bounce to 3G then eventually to 4G. Its everytime I drive out. Not sure if its the path or something .Doesn't really bother me because I shouldn't be using this beast while driving but just noticed if that helps.
Great to hear from you, neighbor! Yes some odd reason the phone bounces in & out 3G then 4G. Its annoying....But I thought it was just me.

I live in Florida and I was noticing my phone jump from 4g to 3g and back yesterday while at home where I normally have solid 4g.
I found the opposite. Cincinnati Ohio tho but my 4G is rock solid on my note II and was ehhhhh on my GSIII

Glad to hear I'm not alone...I was ready to bring the phone back.
I guess the Samsung phones don't have a great antennas. My partner has a Motorola Bionic, his phone is 4G, all day. Other partner has a Rezound his is 3G but full signal strength.
We have the same signal bars strength wise. But his is 4G mine is 3G.

Outside of Philly and my phone was randomly going into 3G the other night. I think it's network related as I restarted and had 4G back.

Yes I too had to restart the phone and I would get 4G.
Wouldn't that be an issue with the sim card at that point? I wouldnt think its the phone because the sim is what recognizes Verizon LTE networks?
Cirrect me if I'm wrong, I want to figure this out.

Restarting causes the phone to re-authenticate with the network. Picking up 4G again is likely just luck of the draw. If a local tower (or towers) are having problems, you may keep 4G until there is an issue, then it'll disappear again until you swap towers, toggle airplane mode, or restart the phone. Without talking to VZW though, there is no telling if it is a network issue, or a device issue. Given the number of people that have seen problems recently though, I'm going to go with network issue.
I have 4G issues as well, seems just a day or so after rooting. I haven't seen 4G since; I've restarted several times, pulled sim card, put in airplane mode. I think I need the "get a new sim card" fix. I am rooted but no roms installed; does anyone know should I go full stock before walking into the store and asking for a new card? Or will I be ok since it's only rooted?
I had 4g issues this morning and this evening (in boston); reboots restored but i have no doubt this is verizon crap; my razr periodically had the same issue. At work i had no 4g issues. Drives me batty - I think the only fix is for at&t to record these issues and start using them in advertisements

Ok..I just replaced my sim from Verizon. They told me there was a bad batch of sims. So they gave me the 2nd batch. Please don't quote me, because that guy was a sales person who tries to sell me everything in the store...lol
I will let everybody know within a day or two.

when i have lte issues I'll throw my phone in airplane mode for a couple seconds, then take it off. works most of the time for me.

I'm no longer having issues, in fact I'm now seeing 4g in areas that were only 3g before. I think it was just network related.
EDIT: See you got it sorted out. Sorry for the bump.
I've noticed over the past few days that I've really been bouncing around a lot. Seems to go through phases.
