Network connectivity issues - Sprint HTC EVO 4G LTE

Hey guys, i have no idea what has happened, but i no longer have 4g on my phone.
First, it takes forever to actually connect to Mobile data. It shows that mobile data is on, but it says "disconnected" for at least a minute or two. Second it only connects to 3g when i know im in a 4g area, and have always gotten 4g.
I have it set to LTE/CDMA mode and have sprint connnections optimizer turned off. I have also updated prl/profile to no avail. Please help
Thanks

It's been around the posts lately about the growing problem. Try ##3282#, profile, change to 1, hit menu, commit modifications... Maybe that will help.

Thanks, it was already set on 1.

Well... I'm in the same boat man. But I'm actually going on a couple hours of constant lte. Man, I did everything in the book. ##786# reset, hundreds of profile and prl updates...
I flashed back to an old nandroid of superlte and its been working.

I'm basically having the same issue. The other thing on my end is I can't update prl or profile. This sucks.

This happened to me the other day. What i did was turn off my mobile data and put my phone on airplane mode for a few minutes. Then i turned everything back on and my LTE worked.

Woke up this morning and my 4g was back! Guess its a tower or software issue. It seems to be randomly disappearing for no reason. Hope you guys get it solved cuz if not then the phone should've been called EVO 3G if its gonna act like this. I'm sure I haven't seen the last of this problem

Been having similar issues for the last day or so as well. It sometimes requires me to restart the phone entirely before I get LTE back. Where are you guys around? Chicagoland area here.

4G still having problems in NY?

Good morning community,
Anyone else still experiencing 4G problems in NYC? It will stay on 4G for about ten seconds,then I will lose connection all together, before it reconnects to 3G.
My radio settings are correctly selected at CDMA+LTE/EVDO auto and I am on the MR2.0 radio.
This has been happening for me since yesterday.
Thanks!
I'm having the same problem and it's been like that for about 3 days now. I'm on CM7 so it can't be the radio.

Have not tried going back yet. Switched to 3G only and that has had a steady signal, albeit very slow......LOL
Verizon had 4G issues about a week ago, maybe there are still residual lingering issues?
not sure what is going on. the first 3 days with my bolt were great. i was on the OTA update (MR1 i am guessing) and had 4G singal at work and everywhere else i went, pulling about 20mp/s downloads all day long. but, for the last 5 days i have had spotty 4G, zero 4G at work. when i can connect to 4G i am getting like 5mp/s downloads. and that is IF 4G doesnt hang and not load anything. starting to get frustrated....not to mention, my buddy who sits right next to me at work has a droid Charge witth 4G and pulling just under 20mb/s here.
wondering if it is a LTE/ thunderbolt issue. the TB and LTE are not playing nicely together. not sure why that would be, but i dont have any other explanation.
having slow/non exhistant 4G with MR1, MR2 and MR2.5 radios.
im in queens. College point. Today 4g has been fine for me.

Sprint mobile data keeps dropping

This just started happening a few days ago. Mobile data drops out..no 3g or 1x. Seems to happen on multiple roms, think its a sprint issue. Anyone else?

Try calling sprint and have them reset your signal.

Welcome to Sprint's 3g lol
Yea sprint is whack in some areas.. some areas it's decent. T-mobile 3g is always consistent and heck even faster than sprint 4g sometimes. They need to improve service because it's not reliable.
Its been like that for me since my release day OG...

soo sloow
will drop pick up in a couple days or get another carrier like Verison, flash Evo 3d to Straight Talk
yeah... sprint 3G has sucked for me for like the last 6 months. I think they are intentionally throttling down and degrading 3G quality in towers where 4G is available. that seems to be the trend I am noticing. This way, it encourages us to move off of those channels and free up traffic for others who dont have 4G. Just a theory. But my worst 3G speed / signal is in areas where 4g is available.
I broke my 3d and had to reactivate my old Hero but i cant get any data cuz the area where my account is active (Dallas 469 area code) is having issues so even all the way down here in houston i cannot get my phone to provision on the network because its pulling from Dallas where the problem is. So i have no data at all!!!! Rep said it would be next friday b4 its fixed but they will credit for the time im without data. WTF?
Sprint offered
received READY NOW service today hard reset, wipe and slate test. I'testing

Try RUU'ing and then doing a factory reset in bootloader. That worked for me.

There's been a lot of problems with people staying connected to 4g in the past two months. There are already a few threads on it. I called up Verizon and they said they are working on a solution. Some people said they got a new red sim card that worked. I have heard its new so I haven't check to see if my sim switch was to the red one or not. I would reset the phone and try the sim switch if it isn't working call Verizon to add to those who have an issue. IRA not just rezounds its all 4g phones accross the country. Right now I am on 3g most the time in a 4g area (it was already 4g when I got the phone in novemeber no probs till June). Anyhow hope I helped.

changing my preferred network choice in the radio settings from "CDMA+LTE/EvDo" auto to "LTE,CDMA" makes a big difference when I'm having that problem in my area.
I woke up this morning to 4g. Mojave desert so cal. Never thought it would get here.

No mobile data/gps

Anybody ever have a problem were their mobile data stops working? WiFi and voice works just fine.My phone shows a 3G signal and good signal strength but when I turn off wifi I get no data. I don't think its the ROM cause I've flashed 3 different ROM and I have the same problem with each. I updated my profile and PRL but it didn't change anything. I got this phone(EVO LTE) on day one and data has always working fine but his just started yesterday.
Any advice is greatly appreciated.
mine just started this today around 2pm. getting ready to call sprint now that im home.
Im about to do the same. If I find a fix ill post it here.

I'm located in Dallas. So I just got off the phone with sprint tech support and they had me dial some code on my phone to bring up a menu I never seen before to reset some setting and my data and gps is now working. They only bad part is that my mobile data only works now when my phone is set go CDMA only and not LTE/CDMA. That sucks cause they do have LTE in my area.

I am having the same problem in Ft Worth. Started this afternoon. I can get 3g data if I set the data to eVdo only. If I set it to cdma I can only get 1x. If I set it to cdma/evdo/lte auto I get no data. I am hoping this means Sprint is working on the towers.

The sprint tech I talked to said that this happens if they are working on the towers. I hope so too. Ever since LTE went live a few weeks ago I've had a 4g signal for about 10 total minutes and I go to downtown Dallas often.

My data started working again this morning. Still the same crappy 3g. It is funny, if I select evdo only my speeds double. On auto mode is get between 50 & 100 kbps, if I select evdo I get between 200 & 300 kbps. I still don't have lte at home, Haltom City. I have seen lte for a few minutes at a time at work, Meacham & Blue Mound Rd.

The sprint tech has to dial: ##3282# and select Edit mode(i can't remember the password he gave me) From there we went to advanced to verifty my MSID. That was corect so we didn't change anything. He said he reset the data on my phone and asked me restart it. After that he had me go into my mobile network settings and disable domestic data and select CDMA mode only and restart again. It's worked fine ever since.

Unreliable LTE connection

Hey everyone,
For some reason my GN3 isn't getting a 4G connection in my home or office, my GN2 gets a flawless connection.
I did all standard trouble shooting procedures with Sprint but no go.
I made sure the cdma/lte option was selected, turned off the connection optimization, reset the profiles and prl.
Sometimes the 4G will turn on, but it will disconnect quickly. Is my phone defective?
Thanks

I know in my area, theyre constantly turning on and off the towers as theyre making the transition to bigger and better speeds.
Hmm.

Sounds defective to me. This phone has a stellar LTE radio, definitely up there with the Note 2.

Yeah a combination of both might really be giving you a horrible experience. This phone is amazing when getting a signal. I switched from the HTC One, which for me was a horrible phone for 4G or just signal in general. This phone grabs and keeps 4g anytime.

Actually it seems better than the note 2, I am getting 4g where my wife note 2 is only getting 3g in some spots. Yes we are side by side when it happens. Yes we traded phones to see if it was just the distance of a foot or two in the truck made the difference. It did not.

The 4g on my note 3 goes in and out. I can wake the phone and as soon as I do the 4glte icon disappears and the 3g icon pops up. No stable 4g connection at. Haven't been able to test the speeds because of this. Now my gs4 is sitting right by my note 3 and it has full 4g getting speeds up to 24mbps. Yet the note 3 is still only showing 3g. Both on the same prl. Both have lte enabled.

I get some issues from time to time; In Seattle, Sprint has yet to officially announce 4G LTE coverage.
I'm lucky to get it where I live and frequent but from time to time it just doesn't seem to work, it will say I'm connected but has DNS errors, perhaps because the connection dropped or they're upgrading a tower... When my connection drops I try cycling Airplane Mode a few times and that usually lets me connect.

I have to cycle airplane mode to connect a lot of times as well. Does anyone know why LTE seems to be so much tougher to connect to than WiMax? On my S2 that I just upgraded from you could set the specific db that Wimax connected and disconnected at as well as the specifc interval that it would check for 4g. It connected to and stayed connected much more reliably than LTE does. I live in a well covered area, but there are certain points along my driving route where the 4g will drop to 3g. After that I notice that it is very hit and miss as far as deciding to reconnect to LTE, even though the coverage is superb. If I cycle airplane mode, it connects with a strong LTE signal. This is after setting the LTE timer and the buffer timer to 1. Does anyone have settings that make the phone try to connect more often?
Did anybody ever figure out why this is happening, i just picked up my n3 while i was in denver where there is no sprint 4g, but i noticed as soon as i got back to my house where my n2 always got 4g and my wifes icrap 5s gets 4g but not my n3?
Here are the settings I use. 4G almost always. connection optimizer is removed on my phone too. If you use something to create shortcuts to activities you can access the hidden menus without using the dialer. Easy prl change is nice but since 4G is new in my area I stay on the newest the phone grabs from network.

Yeah, I'm getting general LTE flakiness lately, when previously it was fine. I don't know if it's the phone or the network. I seemed to have better speeds with my kyocera torque and s4. I'm guessing it's network congestion. In some places with decent signal, it has slow connection to no. Pisses me off when it drops down to 3g. I'm thinking more people are upgrading old phones and hogging bandwidth. Ten months ago LTE was much faster.
You guys think this would work??
