Hey folks, any ideas why my APN will auto-switch to non LTE - Verizon Internet every fourth or fifth time I unlock the screen? It's been doing this for about two weeks since I flashed CM10.1 and Devil Kernel. I've since tried going back to TW as well as wiping everything on the phone including system prior to flashing different ROMs. Right now I'm running CM10.1 08-13 nightly with Plasma 1.67 kernel and it's doing the same thing.
At first I thought it could be signal strength causing it to not connect to LTE, but it's completely switching APN to non-LTE. At wit's end right now because no combination of stock TW or CM10.1 will let it stick.
Guess I should ask my question:
Is there a way to make the APN stick to LTE - Verizon Internet instead of letting it arbitrarily switch to EHRPD - Verizon Internet, which drops my LTE connection? Anyone have any ideas as to why it's switching on its own in the first place? When I'm on the EHRPD - Verizon Internet the phone doesn't seem to ever switch back to LTE, even though what I read on the 'net says it should be switching back and forth depending on signal. I have to go into the *#*#4636#*#* menu and switch it back to LTE/GSM/CDMA auto (PRL) as it has switched to CDMA auto (PRL) when on EHRPD - Verizon Internet.

I am having the same issue, but if I force it into LTE through the test menu I can get data at 4g speed. But it shows no signal.
I thnk it is suppose to be on the VZWINTERNET. I just had this issue with carbon, and I figured out the network options I were using was wrong. I kept choosing LTE/CDMA, but it should've been LTE/CDMA/EvoD and once I did that i got snapepd back into 4g.

On the advanced data menu that is what mine is showing, when ever I select the LTE apn it bounces back to a 3g one.
Got a new sim card and the issue is fixed.

When you flashed the ROM originally and started having this problem were you asked to activate your phone. I am having the same issue after flashing a 4.3 ecliptic one ROM on my HTC One. I was running the same ROM but 4.2.2 before flashing. The first thing I was required to do was *228 for activation. I used option 2 to update the roaming capabilities and after that I could no longer stay on LTE. I was pushed over to ehrpd. Even when I tried LTE only using the method listed above I could not get a connection to the internet (even though it showed APN= LTE).
I will probably just go to VZW and get another SIM card for LTE.
Any thoughts would appreciated.

You will need a new sim. You don't have to activate and especially not update via *228 with a 4G sim card.

Although, I am afraid that I might still need to go to VZW.

Ever since Verizon network went down a few days ago I can't get a solid connection whenever I download anything. Browser seems to load fine. I try downloading several apps from the market but cannot complete the download due to lost connectioime. It will just stop at any time during The download. Same with files. I dont think is the rom. I'm on cm7 pre-release. Flash back to Tesla but still have the issue. Is anyone else have this issue?
Are you close to a 4G area? Try locking your radio to 3G and see if it improves.

No I don't get 4g in my area. How do I lock 3g? I have it set on cdma / edvo auto.

You go into the phone dialer and input *#*#4636#*#*, choose phone information. LTE mode for only 4G, CDMA auto (PRL) for only 3G. You can change it back to normal by using CDMA + LTE/EvDo auto.
I've been having the same exact problem.

Just installed the latest radio and is still having the same issue. I hope is the network then since you're having the same problem too.
I have das bamf remix 1.5 on my phone and I've been having very slow downloads lately when it says I have a full signal.... Tried both modes as mentioned above and problem persists. Can't even load a whole you tube vid. WTF
New radio problems
I had similair issues, and I went back to stock 605.6 radio and a simple debloat rom and it fixed my issues, I am also set to CDMA(PRL) as I'm in a 3G only area
on the new radio my 3G connection was unstable and my GPS wouldn't lock
all of this only occurred after the verizon network went down and came back up.
before that I was having my problem with the new radio. I'm waiting on 605.6 until Verizon officially updates the radio, because I think they changed something that is currently only working with the old radio, the only one they have to support at this time, just my conjecture of course, but I've tried it a few times going between an old radio/old rom and new radio/new rom and it's consistant
Having the same issues. Tried all the radios, but downloading from the market place still goes at a snails place. Like everyone else this started after the lte network went down and came back up.
Update:
Found this on Android Central: Created Cheeta186

Alright, I just got off the phone with them and they fixed my problem in less then 5 minutes. The problem was caused when the network went down, and when it came back up, some of the thunderbolts would not connect correctly causing the connection issues. When I called customer service the woman brought a tech guy on the phone and he had me take the battery out of the phone WHILE IT WAS POWERED UP and then take the SIM card out and he did some kind of "network reset" to my SIM card and now all the issues are gone. Worth giving them a call and seeing if this fixes your problem. IMO VZW has the best customer service hands down, they are always so helpful and will make conversation with you during the luls while on the phone (IE when your phone is booting up).

Can't check this myself yet, because verizon customer service isn't open as of now.
Interesting. I'll give Verizon a call. Thanks.
I was out of town this past weekend. Wisconsin Dells if anyone is interested. While I was there I was experiencing some bad signal, so I read multiple times that you could force a PRL update for your phone to allow it to possibly roam on newer towers. I dialed the *228, then pressed 2. After the update my phone will now only connect to 3g. Even back home now, which I know for sure is a 4g area, I am still stuck on 3g. I spent quite a while messing with settings. The one that controls what network to use. I tried them all really. But its set to LTE/CDMA only right now.
I was running CM10.1 from 8/3. So I formatted system/data/cache/dalvik, everything basically, reflashed the latest build of CM 10.1, and it is still doing it.
Any other ideas before I reflash back to stock and call Verizon?
So I flashed back to stock. Still stuck in 3g. But in the touchwiz interface now it's a bit odd. In Mobile Networks, the list item says Preferred network mode: CDMA/LTE/EVDO. When I touch it, it presents 3 options, Global, LTE / CDMA, and GSM / UMTS. The LTE / CDMA item is selected. The odd part is that even though LTE is listed first on the option when it is selected from the pop up menu, it still says CDMA is first in the preferred network mode, the gray text. That is even more odd is that if I select the GSM one, it doesn't connect to anything, which is expected. But then if I go back into the option and select LTE / CDMA, the status bar icon will say 4g for a half second and then say 3g.
Any ideas?
I found this. Is my sim card really toasted?
https://community.verizonwireless.com/thread/786562
"I was recently browsing a different message board to see what was being said about the GS3's poor reception and data, and I came across a discussion on "updating towers" using *228. From what I read, it seems that dialing this number from a 4G phone not only does nothing to update your towers, but it also destroys your SIM card, and prevents you from accessing 4g. Consequently, you will need to get a replacement SIM card. I find it hard to believe that Verizon would allow something like this to happen. It seems that they would notify their customers when upgrading.
Has this happened to anyone???"
Update: I called Verizon. They confirmed the sim can get toasted if you dial *228 on a 4g phone. So I'll have to go into the store tomorrow morning to get a new sim. The support guy was cool about it. It said he did this exact same thing himself before he started working for Verizon.
Yeah I have heard that dialing *228 from a 4G phone is a big no-no but I didnt know that it actually fries your sim. At least you can get another one for free.

This could be a handy sticky. Just in case more people try/do this.

I wish I had seen this thread sooner and I have been spending days trying to figure out why my phone would no longer connect to the LTE network after traveling to a 3G only area. Whoops!
I definitely think this should be a sticky - or at least warning not to use *228.
Here is my story.
Last night I decided to jump from cm10.1.3. to the latest AOKP nightly. Something went wrong with the flash, probably a download corruption due to the fact that I downloaded over lte. In the install I also overwrote my recovery image with the dual boot devil kernel one. On boot I had problems and couldn't restore my backup. I assembled a flashable package CWM 6.0.4.1 IIRC. I was able to restore and was back in business.
I downloaded aokp on my pc instead of my phone, flashed that, and it was working fine for a couple hours. At some point I saw 2 bars of 3g. I was like wtf, whatever and connected to wifi. I am on an unlimited plan, so this was an inconvenience. I flashed back to cm to get some files I wanted, and went to sleep. still having 3g.
Woke up, 3g. The network must be broken, right?
I meet up with my sister, she has 4g lte full service.
I reboot, see full service, see the 4g icon, then see the 4g icon go away, service drop to 2 bars and the 3g icon come up.
I reflash my radio, 3g
I wipe /system/,/data/,/cache/, restore, 3g
reslash kernel, 3g
Why is my phone dumping lte in favor of 3g. Did I piss off verizon?
EDIT: I just installed stock rooted and still have 3g only
I just got 4g for a minute after cycling airplane mode. it switched to 3g during a speed test.
Edit, I seem to have resolved this by toggling my network mode. I find it odd that this would have an impact across backups.
Edit2 sometimes it doesnt stick on reboot. Also goes back to 3g after a call. This is very wacky.
Now 3g stayed connected in a call.
What is the code to reprovision the sim card? Some people have seen results with this. however the code for the s3 that I found wont work.
verizon is sending me a new sim. I am glad I flashed to stock because even over the phone they asked for my build number.
After setting up, did you by chance change any of the settings in PA to turn on 2g when the screen is off? I was doing this and it would change my network settings to GSM instead of LTE+Evo

nope, in fact I even restored with odin. On a dead stock unrooted rom with a locked bootloader. lte didn't work.
I doubt it is the sim though, because I popped it into my rezound with an adapter and had a really good connection. I suppose we shall see.
These are my current available apns. When I try to create a new one it has a MNC value of 005. 4gtricks.com says it should be 012. If I change the MNC to 012 the system automatically deletes my new APN. Anyone have settings to offer me? Or maybe suggestions. /system/etc/apns-conf.XML is there and full of info.

I just popped my sisters sim into my phone. I instantly had 4g. So yeah, that leaves my sim, or an account problem. But like I said my sim provided me with 4g when I tried it in my rezound.

I set it to LTE/CDMA/EVDO. but still the same no working 3g or late. And idk if this has anything to do with it but when I got the phone they told me that the radio was flashed to work better on at&t so idk if that affects my Verizon network

Not sure what they meant by that, there's no AT&T specific radio. You may want to wipe the phone clean and start over on it.

I had an issue a year or two back and it turned out to be the battery door that went south. replaced the door and was back in business. may or may not be your problem but just an idea.
its not my towers i switched to my gs3 and it connected to 4g fine. i am currently rooted and running the meanbean rom

This isn't in the right section, but the first things to check would be if the data connection settings are correct. I don't have an Evo in front of me, but check in Settings / More... and there should be some stuff there to make sure that CDMA/LTE is enabled or if you just want 3g, do CDMA/EVDO (I'd switch between the 2 to see if it makes any difference). Seems like this is not a totally uncommon issue with these phones. Some people just had issues with the towers updating (even though your other phones work ok, every phone is different and use different radios so not exactly apples to apples), sometimes it was just needing reset (either via factory data or ##72786# which will reset network stuff and redo the Hands Free Activation and update the PRL). That's usually the other thing to check : Make sure the Profile and PRL updates are done. Unfortunately, some users report doing all of that and still never resolving. Good luck!

In the dialer, press *#*#4636#*#*, and choose Phone information, and choose any network type you want, turn the radio off and on again. This may help. Good luck. :victory:
