some time ago i set the phone to LTE in the testing menu to see what LTE networks it could see. it saw them fine but not for the network i use yet.
the thing is ever since then everytime the phone reboots it seems to default back to LTE only. soi have to ga back in to the test menue and set it back to LTE/ GSM to get the signal back.
Help! why is it still doing this and how can i fix it?
Go to Settings, More... under Data usage, Mobile networks, Preferred network type. Make sure the radio button for 3G is selected.
so i cant leave it on 4g preferred? 4g should be coming to my location in the next coulpe weeks so id not want that to be perminant.
or will setting it to 3g reset things?
ooooooh, did as you said rebooted, 3g locked on. sat back to 4g preferred and rebooted, 3g locked on.
yey! thanks, i dont get why it worked but much appreciated.

After doing a manual root, the Thunderbolt connects to LTE fine but when there is no LTE, the 3G won't connect and the phone doesn't receive data.
Advice?
Try checking to make sure you are not in LTE only mode. Dial *#*#4636#*#*, select phone information, scroll down and go down and make sure you are on the CDMA + LTE/EvDo auto option and not LTE mode.
If that doesn't work, try downloading "reset connections" from the android market and running that app when you enter a 3g area out of 4g range. It may be a handoff issue from 4g to 3g towers.
##778# hit dial, edit mode, password is 000000, modem settings, Rev. A, change to enabled, instead of eHRPD, hit menu, commit changes.
try 3G again.
I assume like me, you are in a section where Verizon's Hybrid Network isn't working, and so you must tell your phone to revert back to their regular 3G network.
We have 4G in Pittsburgh, but there's a spot in Squirrel Hill that I go through on the bus in the morning where I drop to 1x, and I'm fairly certain that there is 3G there. However, there are other areas I've definitely seen 3G. So, it seems a little mixed. We're definitely early adopters of this new network
The fix
Phone ##778, edit mode, 000000, modem parms, REV-A change from ePHRD to enabled, menu, commit, reboot, problem fixed.
seems to have worked for me. I was having a problem with syncing too, hopefully this fixes that as well. Thank you!

Not to familiar with TB verizon, but friend bought his TB and I saw there was 4GLTE on it, and now nothing, no icon not in wireless networks, nada!
What is this "fix" for?
I was just exploring my phone and I went onto the hidden menu:
*#*#4636#*#*
From here, I changed the network thingy from GSM/CDMA auto (PRL) to GSM only just to see what it was about. All of a sudden my data connection went from 3G to edge. So then I changed it back to GSM/CDMA auto (PRL) and there isn't a change. I have turned off my phone and restarted but still only get Edge connection. The area I live in has a very strong 3G signal all the time. Is there any solution on how to get my 3G back? Im on stock rom 2.3.4 rooted. I also have the I9020A version from Rogers. Any help would be much appreciated.
*PS I really don't want to do a factory reset
Have you tried mark and unmark "2g only" in network settings?

I'm on bamf soab 1.03 and I dont think anyone else is habing this problem but I'm wondering if anyone knows how to fix this issue. When I get 4g signal the phone will use it but won't use 3g. It drops out of 4g and then just stays without data. So basically its only using 4g or else its just not connecting to 3g. There is no data problem in my area because people I live with are getting 3g just fine....any ideas?
Menu > Settings > Wireless & Networks > Radio Info > Change LTE only to CDMA/LTE mode
if you don't have the radio info option there, download LTE toggle from the market and do the last step.
heh. i tried out the new 1.03 and market just kept crashing on me(even after force stopping/clearing data) and uninstalling updates. so i just thought "to hell with it" and switched back over to shiftao3p
No such setting as LTE only. And my phone has always been on LTE/cdma so its not that I already checked that. I'm not a noob user.
do you have EHRPD on under modem settings in ##778? It should be. Past that I sometimes reset if it has issues locking on to one and that will resolve. That's all for my ideas, though I'm still on SOAB 1.02

This is what i was going to suggest. Here's some information that might be helpful. I've found that with the network testing and stuff the past few weeks in my area, sometimes revision a enabled is better, sometimes eHRDP works better. Try switching revision A and see what it does.
Try dialing ##778# on your phone, hit call if you need to.
Choose edit mode
Password is 000000 (six zeros)
Choose modem settings, go down to revision A, and change from e HRDP to "enabled"
Press menu and commit modifications, phone will reboot.
After it settles you may need to go to *#*#4636#*#* and choose phone info then change your preferred network settings to get a solid signal.

I was messing with it last night and seems that the issue is fixed if it happens again ill follow those steps. I'm a pretty advanced user but I'm not so familiar with those settings so thanks for the help

I'm running a version of 2.11.605.3, de-bloated and rooted.
I lost 3G on October 21st. I would either get 4G, or nothing. On occassion, I would get 1x. Selecting CDMA only gives me NO data
If I change the REV-A option under the ##778# menu from EHRPD to enabled, the 3G comes back and the toggling between 3G and 4G works fine.
Switch back to EHRPD and 3G goes away. Seems like the problem is with EHRPD. I don't know why all of a sudden it stopped working correctly and I don't have enough tech skills to identify the possible cause.
VZW has had trouble with their Data network the last two weeks, could be a VZW problem. I have not had any 3G problems on my phone and I am running SoaB v1.03 on my phone.

Just got my Nexus 5 today.
However, in Wireless&networks / Mobile networks / Network Mode, I can only set it as 2G or LTE but not 3G.
I am currently on b-mobile in Japan and my Nexus 4 works fine on the network.
Wondering is it some sort of bug of KitKat or is it somewhat related to the SIM card I am using...

Probably the sim card. Mine gives me the option, but another n5 on a different network (o2/UK) doesn't.

hmm, in my case, I can see the 3G option, just that whenever I select the 3G option, the system would automatically reset it when I navigate to other page.
Is that also the case on your N5 with O2/UK sim card?
On the other hand, I will test my N5 on different sim card tomorrow.
I have the same issue. If I select 4g, the dot stays when I go back, but I only get a full bar 2g connection. If I select 3g and go back, no dot is there but I only get a 2g connection.
Sometimes this was solved in previous handsets by going into the service menu and selecting 3g/2g from there.

I also tried forcing the N5 to use 3G only (by going into the test menu with "*#*#4636#*#*" code) but it still does not work...
OK, so I tried the SIM cards from my colleges, and my N5 can connect to 3G without problem.
It's weird that my SIM card works perfectly well on N4 but NOT N5...
Did not experience such SIM card computability issue before...

Works for me now. Went into that test menu and selected GSM/CDMA auto PRL and I now have 3g. Didn't have to reboot.
3G cannot set for Virgin UK Sim

I am also having the same problem, purchased the Nexus 5 from carphonewarehouse, can set on 4G or 2G, but when i set to 3G and comeback, it resets. Is that a SIM card problem? I tried to go on testing mode and apply GSM/CDMA auto PRL, that also not working. Is that a KitKat bug?
Same problem on Orange/EE in the UK. I can see the 3G option but phone won't let me change to 3G. Option never sticks. Just stays on 2G. Any ideas? Is this a known bug?
Thanks 101

i think it's not a bug.i think it's a hardware problem. i'm having it with vodafone italy.
Same here on T-Mobile Austria :/
Already changed SIM card, without success. Maybe provider related issues?

I'm on straight talk TT&T with a new SIM card, but sometimes the network mode doesn't stick. No idea why...
replaced a new 3G SIM, no luck
Just replaced a new 3G SIM Card didn't work the 3G option for me - Chunghwa Telecom Taiwan.
But I can select 2G, and dial number to make a phone call, so the SIM slot seem works fine, maybe just configuration issue?!
And, also I find a very annoying defect of my Nexus 5 32G(White), when hard-reset or flash to Factory Image, my Nexus 5 32G white goes crazy!! it just keep stuck and loop at Google Logo (not even show the 4 circle animation), and won't boot at all!
And I finally find a way to make it boot, by keep trying repeat flash factory, erasing userdata, erasing cache etc. is every had this issue?
EE/T-Mobile (uk) and I can't select 3g either, well I can but it doesn't stick.
I have a similar problem, except I can only select 3G / 4G, and not 2G because the 2G option isn't even displayed!! So infuriating. It still works through the *#*#4636#*#* menu, if I select GSM only then it does indeed go to 2G.
Is it possible that the SIM is somehow telling the phone OS it can't do 2G only? This didn't happen with my old carrier (same phone, only just switched). I have a feeling it's caused by the same thing that makes my phone number show up as 'unknown' now, too.
I have the same issue, I tried two different SIM, on is a Straight Talk sim that is set up to use the ATT network and used a T-Mobile sim card, both were unable to keep 3G as a setting.
My Nexus 5 seems that reluctant to drop from 3g to 2g when 4g is selected i have given up and now just manually select 2g to make sure i have a signal (im out in the sticks a bit). Sat at the PC with 4g selected i get no signal whatsoever, with 2g selected i get an indicated full signal strength.
Why on earth the N5 is so reluctant to dip its toe in the 2g territory when no data is on is beyond me.
I really need help with my device, I searched all over XDA and no-one seems to have the same issue as me.
Here is some information:
1) Nexus 6P (H1511)
2) 6.0.1 Absolute stock, no rom, no root, no custom recovery. Build number MMB29P.
Recently got a new Nexus 6P and imported to Russia. All of the major bands here are supported. And the phone worked excellent for a few weeks, but then it lost all 3G or GSM connectivity. Just randomly,didn't do anything with it, the only thing I did is move to another city but than I got back, the issue didn't resolve. LTE works perfectly but can't call or receive calls, can receive sms though. Reseting network settings and factory reset changed nothing. Tried manualy set network to WCDMA or GSM with *#*#4636#*#* command, the moment I switch to anything besides LTE the connection is lost. Contacted the provider, no problem on their side, my SIM works good in other phones, my phone with other SIMs - no.
I don't think it is a hardware issue because a few times I managed to get everything working after an hour of switching networks and bands with no particular order in the *#*#4636#*#* testing mode.
After a while I figured that if I set phone to "GSM only" on USA bands in testing mode, but at the same time set it to "LTE prefered" in the normal network settings menu. I am able to set phone to Band mode 7 and set the network back to 2G in network settings keeping it on " GSM only" the whole time and only after this compicated algorithm and after a reboot 2G and 3G starts working. But any reboot after that revertes everything back to only LTE stage. Also if I get everything working but than reset network settings everything stops working again.
I have no idea what caused such an issue, I really hope someone can help.
