Yeahhhh... I'm at it again, tinkering with the EPST codes and hoping for a miracle. Not sure if I've found the miracle, but I'll share what I HAVE found and you all can help determine placebo or paradise.
My experience: Much like most first round city EVOLTErs, I'm not getting the lte signal as shown on sprints coverage map. Even when it connects, it drops connection pretty easily. So I changed a few things around and walked out of my office building and had a persistent 4G lock for the first time EVER in this location. So try out the below steps and see if your signal improves!
1. Press ##3282# and choose edit and enter your msl
2. Go to LTE record / 'lte available file'
3. You should see a 4 digit entry called SID. Take note of the number most frequently displayed.
4. Now go back to the "Advanced" tab and scroll down til you see the 'Home SID' entry
5. Put the 4 digit number in the corresponding box. DO NOT CHANGE THE NID!
6. Press menu / commit modifications and reboot.
7. Post your results here, cuz I sure hope this helps!
/standard disclaimer: unless I physically make these changes to your phone, I am not responsible for any damages.
..oh yeah, while I'm happy to report I'm picking up signal in a new area, it still drops and goes back to 3G if you don't have it on LTE,CDMA in *#*#4636#*#*. Use those settings to kinda kick start the 4G connection if you get disconnected after a consistent lock (one that remains connected for upwards of 30 seconds).
I dont get or too often, but when I work in boston its not too bad, in gonna have to give this a try though, thanks!

Ok...weird. I show 4139 as default in San Antonio. Perhaps this is a common default setting since it's in Houston too?? My Lte Records show 4181. Very little change when I changed to 4181, but another weird thing...changed back to 4139 from 4181 and saw nice improvement. Thoughts anyone on whats going on? Also tried profile update while on 4181 and it didn't change it back to 4139.

4139 is actually Kansas City, MO. It seems that's the default SID and since Sprint is headquartered in KC it stands to reason that the default would be for there..If I'm understanding correctly, the SID tells the phone what tower list to look for primarily. I'm NO expert, just tryna tinker and stumble upon greatness, ha
Looking at the PRL it appears the PRL http://www.batonrougebroadband.info/
must actually "set" the SID from default Kansas City (4139) to (4181) for San Antonio...somehow. Notice actual SID for a city is unique even though the PRL # is shared by all. Maybe your tweak is short cutting the need to "look at/for" the PRL SID for the city??? Interesting
Thanks for your efforts on this.

I have stated many times before in various threads and other places but I will say it again. That setting does absolutely nothing for Sprint phones. And surely does absolutely zero for LTE. It was originally designed to tell users when they went out of their home network. Not roaming, just outside of their home network where additional charges would be charged to the user.

No, your phone remembers the last SID it connected to and channel. Next time it is fired up it goes straight to it. Every notice your phone take a bit to pick up a signal after starting it up after an airplane trip? It tries the previous known Sid then fails, then starts down the list until it finds one it has listed.

Tried this didn't stick, I do have a 4g tower very close but only connect when I'm at best buy- next to the tower. But at the Cass after trying this I tried a 3g speed test again and was pleasantly surprised... I never get more than 200 down and 100 up in my area.

-I posted this in the Synergy thread, but thought it may help other folks...
After flashing to a 2.3.4 ROM, my 3G speeds completely took a nose dive. I tried flashing different radio combos, updating my PRL, reseting my data profile & updating everything all over again to no avail. I stuck with the latest radios, ruling them out as the problem. I tried flashing different ROMs, and I had the same 1x speeds. After poking around a little bit, I changed my EvDO preferred mode and it helped instantly:
1. In dialer, hit ##3282#
2. Edit mode
3. Enter MSL (if you have root, download MSL Reader from the market to get your MSL number
4. EVDO
5. Preferred Mode
6. Change to from CDMA only to Automatic
7. Hit Menu
8. commit changes
9. reboot
10. *hopefully* get better speeds - I went from 130kbs to 800kbs
I was stuck at 1x at one point and this fixed helped me get 3G back. However my 3G speeds are still garbage, I blame Sprint for that.
If you are having very low 3G speeds though flash a ROM or theme that will allow you to see if your phone is on 1x/3G. If you are stuck on 1x like I was this will definitely fix that.
Hmm. On viper ROM 1.3 its already set to automatic
sent from my DAMN EVO!!!
THANK YOU!!!!
Using the speedtest app (I know it's not perfectly accurate), I got the same thing you did: 130kbs on back-to-back tests. I changed it to "automatic", and hit an average of 1,200 kps!
I ##3282#'d again and put it back to "CDMA only" and I got 130 kbs again. So I changed it back to "automatic" and I hit 1,290 kps (peak was 1,400 kps the first time I did it). All test runs were done within minutes of each other, with the phone laying in the same spot.
MAJOR improvement for me!
Note to anyone trying this: After committing the modifications, my phone would say it was going to reboot but it never did. I had to reboot it manually after committing every change. After you commit the modifications, make sure the phone reboots to ensure the change takes effect. I'll try this tomorrow from work during peak hours where I've always had poor data speeds and see if it improves my data speeds then and there, too.
Thanks again, nol3n!

This may only apply to 2.3.4 ROMs. I think it may be the default setting on the latest update.

You know how people say to go change your proxy settings to 0.0.0.0? Well I've completed removed that and that has helped my browsing A LOT.
The EVO shift had this problem when it got 2.3.3. I think the 2.3.4 roms for the EVO 3d are having same affect. The stock ROM its based off is set to CDMA only or 1xrtt.

Funny,
We had the same issue on the Verizon Thunderbolt -- and had to reset a similar option to get 3G speeds back (phone stuck on 1x)
Note, some roms may say 3G, or have the 3G icon, but be getting slow as molasses speed.
CleanRom clearly shows the icons (1x vs 3G)
Changing from CDMA to Automatic fixed everything for me.
Thanks for posting this.
The default is automatic. If your phone is/was set to CDMA only, then it was hosed up for some reason. I had this happen once after a Sprint rep had me do a reset on all of the data settings. Not sure why it borked it.
You can tell if the phone is in 1x using one of the signal apps that show db readings. If you're on 1x, the EVDO signal strength will be -120db all the time.
I did this last week when I was having problems with my 3g and figured it out. Definitely helped me.

I tried it here at work, and I got improved speeds, as well; although not as significant as I did at home. However, considering I'm in downtown Miami during peak hours where 100,000 people around me have a Sprint phone pulling from the local tower and I'm inside a building on the 38th floor, the improvement is still pretty damn good:
CMDA only = 90 kbs (average of two tests)
Automatic = 480 kbs (average of two tests)
That's over 5 times faster, so I'm happy with the results. My phone seems to roam less while I'm at work, too.
also, if you go to advanced then RTSP/HTTP and change ports to 0 and servers to 0.0.0.0 you will get faster service as well. (4g and 3g) just goes direct instead of a proxy

Yea, I remembered this from my OG Evo and did it to this phone as soon as I got it, but I noticed no change at all. This, however, was night & day for me. I saw someone mention that the default setting is automatic, but I really can't say if my phone came with automatic as default and then it changed after flashing something or not because I never checked it before last night.
Weird, mine was already set to automatic. But i removed the 0.0.0.0 and blanked it out.
Rebooting now.
still works for me, but not everyone..please delete
I am admittedly not very well versed in cellular technologies, but I know a few things. When I click on "Select radio band" it gives me a menu with the heading "Set GSM/UTMS band". With the EVO LTE being a CDMA phone, what good would it do to change a GSM setting?
nice find....almost like a roam only hack. When I choose 800 I immediately start roaming, which at work gives me much better signal.
Hmmm...I did this, and I did get much better reception but it also immediately went to roaming. When I went into settings and forced it to use the Sprint network only...all signal was lost.
Not sure I want to force roaming all the time.
Sounds like Verizon's 800 MHz signal has better coverage in your location than Sprint's signal, and you're forcing it to roam (they have reciprocal agreements).
Definitely YMMV, but hey, it should work fine. Note that Sprint has the option of terminating you if your roaming minutes go too high.

To reverse the effects, just press the multi-task button (or redo the first steps) and choose Cellular 1900. That should put you back on Sprint's spectrum.
I'm not suggesting full-time roam, but it does help if you're ever in a low signal area on Sprint..
I immediately reversed it. It's a good trick to know if you're ever in a spotty area and need to force roaming though.

Don't do this! You can't get it to automatically switch between the two after you choose one.
As a part of sprints network vision they are slowly converting their iden network (push to talk) which is on the 800mhz band to a voice band which will soon result in stronger signal and better coverage for voice. So this will be a good tweak in a few months once that is fully carried out but for now it's just going to throw you on verizon if you select 800mhz

Before trying this; if you use Google Wallet, please go RESET it now, and sync all of your data because this will reset your phone back to stock.
Now try a Reverse Logistics
1. From your phone dial pad enter ##786#
2. Select Menu from the top right corner
3. Select Reset
4. Enter your MSL code (you can call sprint to get this or root your phone and use MSL Reader)
The Phone should reboot and clear all data and system. I know you can just do a factory reset but I did the same thing and for some reason the factory reset and stock RUU did not work for me I had to do the ##786# which got rid of the X, but the data would not come back on, but since I got the phone data has been spotty, but the new PRL has fixed that somewhat.. I've bricked about 3 phones since the launch date trying things I know I had no business, but my curiosity has allowed me to find fixes for a lot of problems except for the NFC bricking problem with Wallet (SO PLEASE RESET GOOGLE WALLET BEFORE DOING THIS RESET).........
Good luck and let me know it this gets rid of the No Signal problem from manually switching frequencies.

rockin my EVO 4G LTE
I found a tower in San Antonio that has 4G LTE broadcasting right now and played on it a bit yesterday. I was driving around trying to find the actual tower and would drive in and out of range. While testing 4G with speedtest or the browser it would freeze when losing 4G and reverting to 3G. I was using a not to be named dual-core awake mod/kernel at the time. Well, I remembered a reason we have dual-core and not quad-core is because of LTE so I went and flashed back to stock kernel. I didn't have the problem today when I went and played on the tower this time.
I may be completely wrong, but I wanted to bring it up to you devs who know more than I do.
This could also just be pure coincidence.
PS
We have some LTE here in San Antonio, now.

Its possibly nothing and really safe to say not to deduct anything from that experience until it is officially announced as "live" in your area...b/c right now they are still blocking from most sites so that alone could be causing issues and the hand off's...
Also without a log no dev is going to be able to troubleshoot the handoff your talking....though i honestly dont know what in the dual-core mod would cause that experience as all its supposed to effect is the cpu clock's which wouldn't touch data management connections in anyway...
Yeah, I know it is doesn't help to not have a log. I posted just in case someone out there wanted to know and if they want me to go and try to reproduce what I was describing and save a log then I would.
It is speculation.
And there are several cell towers in San Antonio now allowing 4G LTE connections.
To find them I have had to toggle airplane mode. Not just mobile data. When you have 4G in the area it will take a bit longer to connect data as it tries to negotiate which signal is best. Then it will connect to 3G or 4G accordingly. If you only have 3G in the area then after you toggle airplane it will go directly to 3G. That pause is the indicator you are close to a 4G tower.
Or if your data keeps dropping out. Your phone is trying to connect to lte but the tower is blocking it

I know the tower isn't blocking it. It's live and is meant to be. I called Sprint to confirm and they even shared with me that the towers by my house are going to be live in the next few days.
I wish I knew what value to change to make the phone sit and try/search 4G longer. Or a way to make 4G the only data connection.

mental note -- do not set phone to LTE only. it does not reference solely data.
Just curious. Where in San Antonio are you getting 4G?
Sent from my EVO using XDA
I really like this phone but want to make sure that the LTE connection issues are able to be fixed with a software update. I hope Sprint isn't BS'ing on this. I have a couple of days to return the phone and want to make sure this is fixable before deciding to keep it.
Anyone know if the Sprint rep who said it's a software issue is telling the truth or BS?
At heart it is a good radio. No reason it shouldn't work as it's supposed to. So, the majority of the issue is software. And it is fixable. Maybe just as good as S3 and iPhone 5 LTE reception?
The big question here is if Sprint will actually fix it this time. Know that there were fixes for LTE in 2 previous ota's. To what extent they worked on it before, idk. Thinking that this time is make or break it.
So, the answer is wait and see. U can get out of contract if LTE doesn't work for u though. It's apart of your service plan. Gonna require persistence on your part to get out after the 14 days is up, but u can do it.
If I were u and needed a good LTE capable phone, I'd go with the S3. Because at this point, it is up in the air if it will receive LTE like it should in the near future.
Correction first update was wifi, second was lte lol
Hope so. Has to be software related since both this and the s3 have the same radio. And, since the airplane mode on/off trick gets it working, I'm lead to believe its software.

Airplane mode trick???
I really hope they can fix this. I decided to keep the phone after looking at the S3 screen and build quality I just couldn't switch. I really love the screen on this!! It is just as good as my wife's iPhone 5 in color reproduction. The S3 is nice but don't like PenTile as I can notice it and I don't like it when whites have a blue color to it.
The Evo LTE has the same SoC as the S3. If the Evo was having hardware problems with LTE so would the S3, but that is not the case (according to what I have been able to look up). Therefore it can be concluded that the LTE issues are software and not hardware.

AKA Airplane Mode Dance
If you are in an LTE area and your phone is stuck on 3G, or if your phone is on LTE and it drops back down to 3G, then toggling Airplane Mode ON and back OFF will make the radio scan and re-latch to LTE.
That's the problem with our EVOs, it's an LTE threshold and handoff problem.
I live right on the edge of LTE coverage, so my phone will handoff to 3G because it decides the LTE signal is too weak. The problem is, in my area a "weak" LTE signal is MUCH faster than a strong 3G signal. If I go into my radio options and choose "LTE only" it will hold LTE signal all day long. So the signal is there, albeit weak.
What we need is a software fix that will change our radio's signal threshold so that it will prioritize a weaker LTE signal over 3G.
I'm tired of doing the airplane mode dance. If LTE is available, I want my EVO to latch on and stay on it even if it's weak.

Can you link it? I'm finding various apps named "network" something or another but none with just that solely as the title
The icon changed so I had a bit of trouble finding it but here you go Network app

Using a Sense ROM, open your phone dialer and type *#*#4636#*#*
Select "Phone Information" then scroll down to "Preferred Network Type" and that should give you the option you're looking for

Thanks guys! Installing app now and have the data code saved for a rainy day as well
Edit : after switching to lte only, I get no data (voice or sms) but im able to run a speed test using 4g. I live in L.A. but I connect to an Albuquerque, New Mexico server I'm not sure what else I'm to do to enable lte only and keep data
It's NOT true for me that switching it to LTE only will keep it connected. I still only keep the connection for about 10 seconds and then it goes back to 3G. My understanding is that option in both *#*#4634#*#* and ##DATA# is "preferred mode." It will drop back to 3G.
And I know for sure that Sprint and HTC have an open ticket on this issue of aquiring and keeping an LTE signal. They will eventually get a fix out for it.
I used the network tool post earlier and set mine to cdma/lte... So I get 4g and voice/text.. no evdo. Which is fine by me because evdo sucks anyway lol.
Works great I now can keep 4g in my house like my gfs gs3 and not switch back to crap-do

Someone try the 10/21 build of cm10 from deck.
I'm holding lte and seeing it places I couldn't get it before even when set to lte only.
This has completely corrected the issue for me.

Preface: About 3-4 months ago I had issues with the phone not locking to the airave for voice calls, but I could see the mobile light (on the airave) flash for data/3g transmissions. Spent a number of hours with airave tech support trying many different things include phone profile refresh, airave profile refresh, prl updates, factory reset, and some other things. None of these helped the situation. Then, about 2 or 3 weeks later everything worked properly all of a sudden. The 3 beeps returned to my inbound/outbound calls when within the airrave's proximity (indicating call is being routed through it rather than an actual tower).
Observations
After some testing on my end, I discovered several things when this issue was occurring.
From the ##debug#/field trail screen (you need sense for this). I was seeing the following:
http://db.tt/Ql4796Iu
When the phone used to work with the airrave for voice, my sid/nid was 4384/502.
When the issue is present, the phone locks onto sid 22439/120 . By all accounts, this sounded very much like a PRL issue more than anything else. The PRL of the airave had a lower priority than this new SID.
I made a post about this issue on s4gru.com. Shortly after, digiblur (our prl expert) joined the discussion and things made alot more sense. (See this thread for the discussion http://tinyurl.com/ayhk79j )
The solution was obvious, an entry to the prl had to be made that gave the airave greater priority than the 22439 sid, but only acted on one particular NID (502 ---- which appears to be consistent to all airaves, regardless of geographic region). So at this point, I knew what had to be done, but not quite how to do it. Digiblur made a very nice how to guide in the post above - see post #16.
Unfortunately, I never got a chance to actually try this out because sid 22439 was turned off and modifying the prl was no longer needed.... Until now!
About a week ago the issue resurfaced and no more airave for voice calls.
FIX:
*WARNING*: Use at your own risk, all typical and usual disclaimers of flashing anything/everything applies here. If you brick your phone, you can't hold me liable.
1) Pull existing PRL from phone
Unlike the old evo, we can't easily upload a prl to the new evo 4g lte by simply referencing a prl file from the dialer. The process is a bit more convoluted
A) Place phone into diag mode -- ##DIAG# in a sense dialer
B) You may need some new drivers http://db.tt/zc4HIsJK, use proper version for x86/x64. May have to manually force the driver.
C) Download the free version of DFS from http://www.cdmatool.com/
D) After installing and running the program (run as admin), select the proper port next to ports. It will say HTC DIAGNOSTIC INTERFACE COMx. Where x is some number.
E) Provide your 6 digit MSL code next to the box label SPC, then click on SPC to submit it to the phone. In the DFS LOG window, it will say "DEVICE UNLOCKED".
F) Just below where the MSL code was entered, click on PROGRAMMING, and just below that, NAM.
G) At the far right of the NAM window is the tool to manipulate the PRL.
Select READ to read it from the phone, then SAVE to save it to a file.
2) Modifying the PRL
You will need some tool to actually make the edits. I Used QPST's PRL editor.
Follow Digiblur's insturctions below - note, due to new prl's, the line numbers have changed, but the concept is the same.
ref: http://s4gru.com/index.php?/topic/2...-but-not-voice/page__view__findpost__p__60555
Ok... here's what you want to do. Scroll down to 465. This should be the 22439 SID record with the Geo set to New. This is the first record in your geographic area. Right Click on the 95(A,B)1x system type of this record. Don't change it, just right click on it and hit insert record. This should push 22439 down one record.
Now look at 4384, it should be on record 473 now. Let's use this as a model for our new record.
1.On the blank #465 record, change it to 95(A,B)/1x.
2.Change Neg/Pref to Pref (if you put Neg, this tells your phone not to use this)
3.Geography is going to be New (will change the one below it in a few)
4.Priority will be More (means this record has more priority than the next one)
5.Acq Index will be the same as 4384 (tells it which channels to scan), should be 14.
6.Roam Indicator should be a 1 (1 = Sprint, 160 = US roaming icon, 228 = international roaming)
7.Assn Incl Should be Yes since we want EVDO
8.Assn Tag will be 16 to use the value 16 flagged records in this Geo for EVDO.
9.Pn Assn should be No
10.Data Assn should be No
11.SID should be 4384
12.NID should be 502.
Now very important, don't forget this. On record 466 (22439 SID) you need to change the Geo to Same.
I would also change the Preferred Roaming List ID at the top to something like 25996 or something weird so you can check your settings/about screen from time to time as Sprint will automatically update your PRL sometimes.
So basically what happens now is when your phone does a network scan it looks for 4384/502 (your airave) first. If it can't find it, it looks for the 22439 on 800SMR, if it can't find that it will look for the 4384/65535.
I haven't tested this as I have no way of testing it in my area so please let me know if this works. In theory it should work though.

Here's what the finished product looks like on PRL 25010, line 460 was added.

3) Uploading the modified PRL
A) Referring back to step 1G above, simply load the modified prl into the DFS tool, then click write to submit to the phone.
B) Exit diag mode in the phone by pressing MENU, DISABLE
C) Reboot the phone
NOTE: If you don't have QPST or don't want to go through the hassle of modifying your own PRL, below is the modified one. It's based on PRL 25010; I call it 25011.
25011.PRL http://db.tt/wk9muM1j
So now, when at home, the phone locks to the airave for voice, and either LTE, wifi, or 3G (via airave) for data. Also, it transitions properly too. When the airave is unplugged, phone locks back onto SID 22439. When the airave is again available, phone locks back to it.
Although my particular signal level is acceptable when on the 22439 sid, the airave signal is obviously much stronger. A side benefit is better battery life.
So if I have an airave I can just change my PRL to 25011 using QPST or do I have to follow all the steps above?
BD, I wouldn't do anything unless you're having the issue I was.
Yea I have not had many problems with my Airave until last night the mobile light was flashing for hours it finally went green on it's own, may have just been a Sprint thing who knows and thanks for your reply
Flashing trying to establish a connection, or flashing because maybe someone else was locked on to it... Did you get the usual 3 beeps when making a call?
My issue came to be mainly after LTE was lit up around here. That's when I started noticing the phone connecting to that strange 22439 sid and handoffs to the airave were flaking out.
To be honest I was told when someone connected to the Airave there was a beep but... mine has never beeped even when I make a call. So maybe I have it hooked up wrong.My setup is modem to router to Airave. I had it modem to Airave to router before but I noticed my internet was slowing down could be all in my head but after I changed it my speeds went up
The three beeps I refer to are heard on the HANDSET's earpiece. Not from the airrave itself. The flashing top light (Mobile light) flashes during the device's init process and whenever there is a voice/data connection in use.
As for hooking up, modem - router - airave should be fine. Considering how much grief it's caused, I don't trust it to function as a router. In fact, I have a dedicated lan port on my wrt54g that separates the airave onto it's own subnet so it's completely isolated from the rest of my network.
Ok I was wondering why all of a sudden my phone would beep when I made a call hahaha thanks for clearing that up
I was having the same problem... So I called sprint and they sent me a new 2.5 airave. 2 days later perfect connection and faster 3g... Cost for me - $0.00
^^How did you describe your problem to them?
I told 'em mine would work for data but not voice.
They never offered to swap it out for me. Too late now.

I told them nothing worked.. then they had me trouble shoot over the phone... Only one light would come on before during and after. So the tech said that it was shot and they would send one out..

2.5 airrave?? I'm curious which one that is, i have a tall white one, my evo 3d would connect fine but the evo connects sometimes and usually it wont, also when my phone has lte (at home) it randomly drops to 3g or 1x and does a dance...
Sent from my EVO LTE 4G
Thanks!
I stumbled across this thread after a frustrating 3 days, and 8+ hours on the phone with Airave support. I don't have an Evo, but I do have a Galaxy S3 and was experiencing similar problems. My GS3 would not connect to the Airave 2.5 at all. They suggested replacing my handset (for a refurb, nonetheless), but I was convinced it had to be something else.
After installing your modified PRL, it works perfectly. I connect to the Airave with no problem for voice every time.
Thank you! :good:
The prl i linked in the OP is a bit outdated at this point, but the technique is still good. Grab a current prl from one of the prl threads and just apply the change.
Attached is a modified 16013 prl. I renamed it to 16913 .
After downloading just rename to 16913.prl, it's not an actual zip file.
You an also dial *99 it will now connected to air rave coverage

@gpz1100, two questions. First, I have done this yet my phone will still randomly prefer anything over my airave. Using the modded PRL used to work but about 2 weeks ago quit. When I say anything, Sprint PCS, Sprint 1xA or even Verizon. Been through all the support stuff, went back to stock PRL and activation. Thoughts??
Second, when I use DFS to read the PRL and then save it, the PRL file is 0 bytes. I can load up a saved PRL file and write it to the phone no problem so the basics have been covered. This would be a S3.
It seems you've left the big S though.
1) Need to where in the PRL you've added the airave sid/nid combo. Location makes a difference because entries at the top have greater priority than those at the bottom. Use a tool like cdma field test tool to determine where you're actually connecting. Then see where that SID is in the prl relative to your airrave sid.
2) Something is wrong, are you unlocking the device properly before reading the prl? Perhaps you need to use a 16 digit password to read the prl? I'm not familiar with the s3, so you'll get little help there. Maybe check in the s3 section to see what's required to successfully read a prl.
3) I am officially done with sprint. Good riddance. Going on over a month now on a big red mvno. Data much improved over sprint.

I actually went to the last entry in the previous Geo and over-wrote that with SID 4418 NID 501 which are what my Airave is transmitting on. I made that entry "new" for the Geo I'm in and changed the previous first Geo entry to same. Digiblur suggested I see what channel my Airave was transmitting on to make sure the channel was in the the acq record for me Geo. That channel was not so I added it. From then things were great until about 2 weeks ago. Since then it seems several people are having problems connecting to the Airave's.
The device gets unlocked, I get message indicating so in the DFS log.
I dunno. Frustrating.
Ok so I too had this issue with my evo4g lte not connecting to my new airave 2.5. I called airave customer support and after trouble shooting some things the tech finally pushed a new prl to my phone and all was taken care of. I am using prl 61096. He said if my phone tried to update the prl automatically I would loose the ability to connect to my airave so I just switched back to cm10.2 after I hung up the phone with them and I haven't had an issue with it yet.
If you don't have a need for huge data consumption, and verizon has good coverage in your area, come to the darkside - prepaid... Even save a few bucks!
@SleepyS40, you are very lucky you got a competent tech who understood why it wasn't connecting. Those are few and far between (competent techs that is). Had you remained on sense, sprint could potentially push a prl update automatically.
