Is this the infamous Nexus 3G problem?

before I got my phone I read about all the 3G problems people were having.
when I first got my nexus, there were no issues at all. no dropped service or connection.
I'm in a 3G area (looked at tmobile coverage map) and I see no reason for this to be happening.
my phone will show that I have 3G connection (UMTS) but when trying to use anything that requires a connection, it fails.
on the other hand, HSDPA network works fine and so does EDGE.
I got my phone over a month ago and this hasn't started happening until recently.
I'm always on EDGE network now and if I'm not on EDGE, I have to be on HSDPA in order for me a to send messages or use data connection.
UMTS is broken and does not give connection. I want to call HTC and see if they can replace it but I don't think they'd do it.
anyone else have the 3G problem? I'm sure a lot do, but is it only with UMTS?

This is not the "3g issue" everyone talks about. This sounds like you are either having network issues in your area, or did you flash a new ROM to your phone recently?

I had been on a CM test build and hadn't flashed a rom in a long time.
network issues isn't the problem because my friends G1 yesterday had 3G and I had EDGE.
I don't think it's my SIM card either, not even two years old.
I'm tempted to call HTC because this happened out of nowhere after a good month of no problems.

99% of the time it's a carrier issue.
When the number of users on a carrier grows or jumps on the carrier, the tower signal shrinks it's radius. And if you're in two competing tower areas, then your signal might drop/fluctuate because the phone is swapping between them.
Nothing the phone can do about it. It's probably your carrier issue.

how can that be when my friends right next to me have full bars and 3G while I'm on edge?

Change your settings to WCDMA only then.

I've tried and all I get is no connection or occasionally hsdpa.

I have experienced something like this. I am unrooted and few weeks after having the phone I would see a 3g symbol but be unable to access any data. It has been very frustrating once but generally it kicks in again with a reboot.
A similar issue since installing froyo is that the stock browser wouldn't connect. Other browsers and applications could access data but the stock browser couldn't. It started again later but I now use xscope.
I love android but I hope that the continue to work on its stability because it could be improved

so is your 3G working now? I'm just going to call HTC and see what happens.
I've tried WCDMA only, flashing a radio, and anything I can find on the web but no luck.

Have you tried modifying your build.prop? If not, do a quick search and see if modifying it helps...

Enabling HSDPA on Jelly Bean

Hello guys
I have been performing various rom installation on my Samsung Galaxy S GT i9000 but everytime it was only GingerBread Based roms.
The second i switched from to ICS and to CM10 JB now, the problem i have been facing is network mode option which is not present in GT i9000 when i was on ICS and also in the present CM10 JB.
I tried many thing but none worked
NOT WORKING
again tried to enter the code *#301279# but that also dint worked.
And my network is 3G enabled since i have tested the same sim on my another phone which is a SGS II running on stock ICS and 3G is working perfectly fine on it.
So basically to enable 3G on my I9000 i would need to change my network mode which at present is not available in my mobile network settings.
HELP ME OUT.........!!!!!!!!!!!!

I must say that you din't even helped me with your statement as i feel you haven't read my problem properly. We have the best network signal availability in my area at present and as i said 3G is working perfectly fine on my sgs II which i already mentioned because i'm able to select the network mode manually from the mobile network in wireless & networks settings.
And not to forget the sim i used for testing 3G on my SGS II in actual belongs to my secondary phone - SGS GT i9000 which is currently running rooted and Running on CynogenMod 10 which is in alpha stage,
And for the data usage on - dude i'm no noob to post this question without me knowing how to use a phone properly.
And hey i did have my data usage on but in that attachment the data usage was off and it was just to show that there is no network mode selection available in the mobile networks settings.
I HOPE YOU GET IT

Hi there,

Thank you for youre help

Try to switch your mobile network mode to "GSM only" and then back to "GSM/CDMA auto". Try rebooting your phone, clearing cache/dalvik or fixing permissions.
Also, as far as I know, some ROMs do not support auto switch between 3G and HSPA (3G icon is displayed all the time). Usually custom ROMs switch between H and 3G to save power (H is used only when bigger network traffic occurs, in order to speed up your download speed), but many ROMs do not have this feature.

Forcing 2g, rebooting, etc., doesnt worked. I know that H is used for big traffic, but ICS dont even want to enter it when i download 10mb+ files..

hey there
as u might have seen im on eplus too and i faced such an issue several times with different phones
what i figured out was that in some cm9 roms the mobile hotspot (dein zugangspunkt ist ja normalerweise glaub ich internet.eplus.de ) is not available or there are mistakes in it so just get to the eplus providers homepage and check if ure zugangspunktname and all the other options dealing with it are set right
hauste rein

Everything was ok, now i changed back to gigabread+ from texten...
HSDPA works fine, seems so that ics is blocking connection like divibyzero said.

ICS doesn't block it you probably need to set up your APN correctly which is what I think the guy before me was saying too

Can't switch from GSM (Prl) in diagnostic menu

Hey everyone, possibly an easy fix but its alluding me right now. For the life of my phone I cannot switch off GSM in the hidden menu to LTE. Currently running the latest PAC ROM on AT&T. I've done several clean flashes if this and multiple other ROMs with no luck. Factory reset when switching from Sense to non-sense based. Tried previous backups that I know had LTE working. My APN is correct, I've checked it several times and even got my tech support team to help out ( I work for AT&T) and we're kinda stumped. Again this may be such an easy fix I'm just not thinking about, so I apologize in advance. PS I did attempt to change APNs and preferred network, but none stick.
Thanks again for any help and all the awesome work being done for our phone

Same Problem Here
I am also having the same trouble.
I am using the Unofficial ParanoidAndroid 3.00 and had previously tried Touchwiz UX Nature Jelly bean ROMs. In both I was unable to change to change the preferred network from GSM/WCDMA in both settings and using *#*#INFO#*#*.
I on Virgin Mobile in Australia though. I've had 4G activated on my network account, have the correct APNs, and can confirm that I get a 4G signal when using the Borked ROM 3.7. That ROM works perfectly for me, but it isn't Jellybean and so there are too many features missing, and it looks ugly.
I've also checked the build.prop file and find all the settings are correct.
Code:
ro.config.lte=1
telephony.lteOnGsmDevice=1
ro.telephony.default_network=9
ro.ril.def.preferred.network=9
I have noticed in *#*#INFO#*#* when I set it to LTE Only and the reception goes to zero the Current Network says Telstra Mobile instead of Optus Mobile as it should for 4G Virgin Mobile Customers.
Could be something to do with the APN not being recognised as LTE capable somewhere?
Could it be something to do with the radio? The ROM that worked used a .19L, whereas the PA ROMs use .22L.
I have tried reflashing the ROM (wipe cache/dalvik, flash). I have tried using 4G from a clean flash.
I have run out of ideas @[email protected] And now starting to wish I saved that money for the One X or stayed with my super reliable Incredible S which even has a super fantasmagorical and stable JB 4.2.2! @_____@*

no lte. tmobile note 5

I've only been getting 4G since I rooted my phone and flashed the unlimited tether hack. No LTE at all, the sim status says hspca or whatever 4G is called. Any suggestions?

When you dial *#0011# what does it show you connected as?

Attached a screens hot hopefully it works

I am pretty sure I read that VoLTE and WiFi calling both do not work after flashing the custom kernels. I am not sure if they all break VoLTE but start doing some checking on the kernels and see if you find one that works better for you.

Flash Arter97. Wifi calling and Volte works. You will also need to install xposed. That fixed the issue for a lot of people.

Tried other roms and kernels and still nothing. My girlfriend is sitting next to me and she gets full 4g lte on her tmobile note5 (which is what mine is) yet my signal jumps from full to 2 bars and I'm still only getting 4g. Checked my apn settings used Odin and went back to stock completely and even tried the new baseband.....still nothing.
