TL;DR Toggled networks, lost connection. Mobile Networks options changed. Toggled again and things reverted back.
NEXUS 5 - 4.4.4 PA-HAMMERHEAD 4.5-BETA2
Toggled between mobile networks using the quick settings and suddenly my handset lost connection to the towers.
I updated via OTA to PA-HAMMERHEAD 4.6-BETA1 and then thought possibly it was an issue with the modem.
Then downgraded modem to M8974A-2.0.50.1.13.
No connections still.. then noticed on drive home from work - 1 small bar of LTE (typically I have full LTE in this area and full voice).
This morning, same situation, and I contacted T-Mobile and they attempt to reconnect my device to the network.
What was interesting was that the settings options for Mobile Networks changed. Initially when the tech asked me to navigate to Settings > More > Mobile Networks the options displayed were LTE, 3G, 1X, GLOBAL and he sounded very confused. The settings would not allow me to toggle from LTE - except for one moment where a 3G network connection went through and my radio came back to life. Then was instructed to toggle back to LTE and it went dead again. At this point the options changed to LTE, 3G, 2G and once I toggled from 2G to LTE, things appear to be back to normal.
I've read that there have been some issues with the Nexus 5 in relation to this toggle and just wanted to share.
Same issue here, i tested every modem and few kernels so it's ROM related.

Hello folks!
okay, the facts are: Im in very good 3g reception zone, MIUI 1.6.6 with default kernel, .08 radio, data on, wifi off.
Problem is poor battery life when 3G is enabled. Also, when using mobile data the H icon appears and data moves in and out, but sometimes the H icon just disappears and i get network error? I've tried numerous radio/kernel/rom combinations.
When i put airplanemode on, the battery consumption is constant 2mA (currentwidget). With 2G networks only, its 3-6mA. When 3G enabled, mostly the consumption is 20-40mA and sometimes like 10 times in day with minute interval of refreshing i get 8mA readigs. Any app to check if there is some syncing going on? I use only beautyful widgets weather widget, which updates itself hourly. And the normal contacts and calendar sync on. Fellow MIUI users have much lower consumption, a mate of mine gets 2-4mA when 3g enabled.
3g mobile network is one the battery killers. The h icon stands for hsdpa. This the fastest network but the network coverage is not that good yet (except for big cities). Switch network to 2g network (mobile off). If you really need mobile network, switch on 3g. Otherwise stay with 2g. There's imho no sense in using 3g without needing/using mobile network.

I tried using BatteryFu and APNdroid to get rid of my 3G while screen off. But that combination didnt work so well, sometimes it didnt disable my 3g and sometimes it wouldnt reconnect to 3G when unlocked. Any good programs to manage this?
I also wonder, I never cant download anything when 3G icon is appearing in statusbar. Its normally 3G but when I want to use the internet, it changes to H. Why cant I use the 3G network then? Im also having problems when the H goes to 3G the internet connection is lost. For example in market i get network error. The H wont stay there if there is no traffic for few secs.
Configured apn correctly? If you are not sure, do it again. Furthermore, you could try these settings for mobile network:
Uncheck data enabled and set network to 2g/gsm (depending on what you have). When you need mobile network, switch to "wcmda + gsm (automatically)" (name could be a litte different, translated it from germany) and check data enabled. I do it so and it's working fine.

Okay didnt understand very well what u ment by the last part of ur message
APN configured correctly? I have carrier default APN settings which have been working just fine for a year. If u ment APNdroid i didnt do much configuring with it. Gotta give it another try.
Last idea: flash latest radio.
No warranty for any damage.
I recently switched from AT&T to T-Mobile, and like the rest of us was suffering without 3G due to our lack of compatibility with the 1700MHz WCDMA that T-Mobile uses. One of my friends (a T-Mobile employee), however, informed me that it is indeed possible to get 3G by using the 1900MHz band, which T-Mobile is currently re-farming to support WCDMA. This trick is simple and easy, and I've had success with it thus far, albeit only in one location as of yet. There is a downside, however... as long as the trick is in place (as long as your phone is set to "WCDMA only" below), you cannot connect to EDGE. In other words, in an area where there is no 1900MHz 3G coverage, this process must be reversed to fall back to EDGE. As such, you may lose connection randomly and be completely unaware of it for hours, and I will mock you openly for attempting to blame me if you lose your job because you missed a call from your boss, lose your girlfriend because you stopped texting her, or lose your bacon because your remote bacon-protection app couldn't connect.
Remember, this is in the testing phase. It WILL get better over time and hopefully one day we won't even have to consider whether a phone supports 1700MHz... for now, though, report your findings below, preferably with location, signal strength/type, and down/up speed.
==PROCEDURE==
Go to dialer and enter *#*#4636#*#*
In the menu that pops up, tap "Phone Information"
Scroll down to the menu labelled "Set preferred network type" (it should be the first one) - this will likely be set to WCDMA preferred
Change it to WCDMA only
Switch to your main Settings app, then navigate to "Mobile Networks" (under "More..." by your Wi-Fi and Bluetooth)
Tap "Network Operators" and wait for the search to complete
Tap T-Mobile if it appears in the list
Once the phone has acquired a signal, you can return the Network Mode setting to WCDMA Preferred. Your phone should now switch back and forth between EDGE and HSPA+ fairly reliably.
===My Results===
At my home (approx. Colfax and Yosemite in Aurora, CO) I get 0-2 bars, mostly 3G but some H+ if I'm holding my phone and moving around, and 2-3 bars H+ if I set my phone down. Speedtest results range between 4 and 10 Mbps, with around 90ms ping. I've been keeping my phone set down with wireless tethering enabled, and it's been 100% usable thus far.
--Update--
Having used it daily for a few weeks, I'm pleased to report that there is moderate to good connectivity to at least 3G in most places. I still find myself on EDGE regularly, but I usually can get a WCDMA connection. Now, however, I'm annoyed because I exceeded 5GB data usage and am being throttled to below-EDGE speeds, which defeats the purpose of having 3G. >_<
what about AWS band ????/ its work

Almost certainly not; see here.
If you have it working for some reason, go over there to tell everyone.
I'll test this later tonight. I'd be cool with 3G or H+ if it works. I have a T-Mob pay-by-the-day sim card that I'd like to use to tether my Nexus 7 to when I'm traveling (which is fairly rare).
I'm new to all this but how is this different from changing the APN settings?
Is this method better than changing APN settings?
This didn't work for me, Portsmouth, NH. It picked up the T-Mobile network in Network Operators but when I tried to select it it took forever and then said unable to connect, failed to register. Attempted a few times on a ucdlk3 stock based custom rom (Intergalactic II) and also on stock rooted.
Probably just not in a good location for this to work.
Sent from my Nexus 7 using xda premium
I have a galaxy nexus
ROM : XenonHD 4.2.2 (tried Stock 4.2.2 for 2 weeks)
Baseband : 19250XXLJ1 (was on earlier ones as well)
Kernel : Stock
Location : Bangalore(India)
Connection : TataDoCoMo
My internet (primarily using 2g, sometimes 3g) and it drops very often.
To enable it, the below steps does NOT word:
1. Toggling flightmode
2. Restart mobile
Only one step works (75% success)
Manually search for network and select network automatically and sometimes to manually select the network.
Please help.
Update: (Strict 2g mode enabled)
I've been sitting in my seat since posting the previous post. Checked my internet and i do not have data connection. Gonna enable it now.
Even manual selection of network dint give me data connection after waiting for 5 mins.
Enabled and disabled flight mode - waited for 5 mins - no go.
Gonna restart and check - last option - no go.
Now i disabled data - strangely, i lost signal for a few second.
Enabled data again - waited for 2 mins - and walah it came.
I dont know on what basis the internet comes and goes like this. It is not humanely possible to do all these steps, just to get the internet enabled. Can anyone help me from this plight.
Can anyone please offer some advice?
You can change rom, and check if it will be fixed.
What kind of network strength do you see in “Status“ page in settings? Post a screenie.
Try a different ROM to be sure it isn‘t a network fault.
Final solution to my data drop issues

Tried stock as well as PA. So i guess its not a ROM issue

I tried a lot of methods and this worked finally. Am on latest radio release I9250XXLJ1. Browse and install it if you are not on it.
Dialed *#*#4636#*#*
selected "Testing"
Selected "Phone Information"
Scrolled down and set the option of "Set preferred network type" as GSM auto (PRL)
Noticed change in GSM Service, GPRS service.
Next time, this dint work tried the below method and finally worked.
At the bottom right corner, the properties option indicated by 3 perpendicular dots took me to change Radio Band.
I tried with the first 5 option with no network coverage and finally AUS Band started giving me uninterrupted data signal.
Success...
Is there a method to switch to 3G when I'm in certain area? My work has fairly weak LTE signal and my phone is constantly switching between 3G and LTE. I would like to set it so that when I'm at work, the phone will use 3G only and LTE everywhere else. I tried checking tasked but I just can't figure out how.
Thanks
Settings -> connections -> more networks >- mobile networks -> network mode... select what you want there.
When I leave my wifi range, network doesn't switch over to LTE automatically. Toggling airplane mode doesn't seem to help. I need to reboot phone for lte to show up.
I googled around and found others with similar issue but no solutions. I'm wondering if there's a solution now since the issues posted on google seems to be around 1 year old.
I'm running CM12
I've been having this same issue on cm13.. What I have worked out. If you use GSM/ CDMA I don't have an issue connecting to data. It's when I use LTE is when it doesn't connect.
Sent from my LG-D851 using XDA-Developers mobile app
I had this same problem. It only happened in CM13 not CM12. I noticed a difference in the APN Protocol settings in CM12 and made the same change in CM13. I solved this by going to Settings > Cellular Networks > Access Point Names > T-Mobile US LTE and changed APN protocol from IPv4/IPv6 to only IPv4.
