I'm a smartphone noob [though slightly above-average with technology in general] - the Nexus 4 is my first smartphone, and I've been lurking here for a week looking for all possible solutions for my problem and none have worked, so please bear with the longish post:
Nexus 4 16GB, bought from the US Play store - using it since Monday, Dec 10. I'm using it with a Straight Talk AT&T SIM, and I have *no cellular data* whatsoever. I have been using the phone for a week now, and I haven't been able to use the internet except on wifi. No 3G/EDGE/HSPA+ logos next to the signal bars - in fact the signal bars always grey when wifi is off. I have only seen the signal bars turn blue when the wifi is on, never on a cellular network.
APN settings have been verified, and tens (yes, TENS) of Straight Talk reps have said my account seems to be provisioned correctly and good to go. I have tried all the alternative APN settings suggested for Straight Talk on various forums, including the two-APN configuration for MMS and data, deleting the data proxy from the APN settings, reverting to the default APN settings on the SIM and even using the Straight Talk T-Mobile APN [though I know for sure mine is an AT&T SIM because T-Mo doesn't cover my workplace, where I have good signal strength].
My old device was an AT&T locked dumbphone, so I couldn't change the APN settings on it to use the data on StraightTalk, but when I put my Straight Talk SIM in, it shows the 3G logo next to the signal bars suggesting that my StraightTalk account is probably provisioned correctly for data.
Hard reset, repeated reboots and repeated toggling of data and airplane modes have all been tried, and nothing has changed the situation. I have perfect voice and text messaging connectivity and zero data.
As a smartphone noob - is there a separate radio in the phone for data connections, and is it possible that this radio alone is a lemon on my phone? I *do not* have access to another micro-SIM, unfortunately - CDMA is popular in my town and the only two of my friends who have phones with removable SIMs probably won't appreciate having their regular SIMs cut down to micro for me to test. Without being able to test it, I don't know if I should just RMA it either.
***UPDATE*** : FIXED
I got a T-Mobile SIM to test the phone, and data worked perfectly well on that, so I concluded it probably wasn't the phone. T-Mobile wasn't an option for me though, because they have crappy reception in most of my town.
Happened to travel to Boston, tried my StraightTalk SIM in a friend's phone there - data worked fine then. So now I didn't know if it was the phone or the SIM.
After three weeks of grief and fighting, I got StraightTalk to send me a replacement SIM, which fixed the issue immediately - I had full HSPA data connectivity within five minutes of dialing their number to have my SIM activated.
Turn on Mobile data?
Have you enabled the 3G/mobile data switch built into android? Settings > Wireless & data > More > Mobile Networks > data Enabled Tick that if its unchecked, Im still waiting for mine but my HTC explorer running a vanila flavour of ICS has a similar settings menu, its somewhere along those lines bud, post back with results. As i said might be in a different location due to the differing OS versions
Good luck mate, Blewk
EDIT: Nevermind ive just opened my eyes and noticed you've tried it xD
so try calling this number *#*#4636#*#* and going through each of those settings (apart from LTE of course) see if any of them give you a Data connection. constantly checking the data switch on the phone at all times though making sure its enabled If this offers no luck im out of ideas for you mate

Thank you, but I have done that too. That isn't restoring connectivity.

So what are your APN setting? Can't really trust CSRs since they aren't using a Nexus 4 to test themselves.

I've attached screenshots with the current settings, which are the ones the CSRs recommended.
I have also tried
deleting the proxy+port
changing both proxies to addressort format
changing the APN type to "default,supl,mms".
editing the SIM's default APN values to these, instead of creating a new APN.
and various combinations of these. None of these have helped. (I reboot and wait 30-45 minutes after every change in these settings).
EDIT: addressort is address(colon)port. Forgot to disable smilies.
Try changing your MMS Proxy to 66.209.11.33 see if that helps. Its the only difference I can see.

Thank you, I've tried that too. Since my other phone (without the correct APN) still shows the 3G logo next to the signal bars and the Nexus 4 doesn't show any data speed indications, is it safe to assume the issue is with the device and not the network?

Thanks. I was trying just that (saw the *#*#4636#*#* code on another forum), and none of the options work. I'm wondering if that means my radio is dead. I don't want that to be the case, but I can't think of another explanation
You appear to not have an APN type set up.

Edit: use these settings. Except in the first APN remove the first proxy line.

I think I have the same problem as the OP. In my case, the HSPA radio connects about 50% of the time after a reboot. In my case, I'm convinced that the loss of signal is attributed to failure to communicate with the SIM card.
For the OP: Are your signal bars grey? or is it just an outline of a triangle on its side? If it's just an outline, the phone sees the SIM card, but cant retrieve the necessary data. To confirm, install a SIM info app from the Play store and see if the app see all details of the sim card.
I have already replaced the sim card, assuming I had a defective SIM, but the new card has not resolved the issue.
At this point, I think I need to RMA my phone.

It looks like the SIM details are being seen - I have voice and texting capabilities, and my signal bars are present but grey. Sorry to hear about your phone - my data connection is out 100% of the time though.
I've ordered a T-Mobile SIM to check this out - this way I should be able to figure out whether it's the network or the SIM.
Update: I've tried a T-Mo SIM and it works perfectly. So it's not the device.
However T-Mo isn't actually a viable option for me because they have very limited coverage where I live. Straight Talk keep telling me their provisioning is okay - any way to check on this? What other issues could I possible have that might be causing this?

Are you sure you have AT&T 3G coverage near you? I looked on AT&T's map for my work place and it shows 3G coverage but the entire county only gets 2G EDGE. And EDGE is horribly slow, I can't download anything. Went to Wal-Mart there and went to the wireless store and they confirmed that there is no 3G coverage in the area except for Verizon (which I had before this phone). I have an app called Network Signal Info, it will tell you what type of data network you are connecting too even when on wifi. It tells me EDGE2 at work HSPA at home.

Edit: just wanted to add that I read somewhere in a thread here that the colors blue and gray only signify if you are connected to google services or not. Blue you're connected, gray you're not.

Dead sure - as I said in my original post, I put my SIM back in my old (locked) dumbphone and it shows the 3G logo - though I can't use data on that phone because I'm locked out of the APN settings. And colleagues at work with have HSPA+ on AT&T. I can't try their SIMs though, because they don't use micro-SIM.
As for signal bar colours - even if there is no Google connectivity, it should at least show me a 3G or H/H+ next to the signal bars, which doesn't happen - and I cannot access anything on the internet anyway. I tried actually accessing the internet via the browser and various apps, I'm not deciding my connectivity based on the bar colours.
ALSO: When I use *#*#4636#*#* to turn the radio off and then on again, "GPRS service" goes to "connecting" but eventually stops at "disconnected". And the "network type" in that menu says "HSPA", so it looks like the network is kicking me off though I can't for the life of me say why that's happening.

I'm constantly get this issue where the signal bar becomes just an outline every minute or so and I lose connection. When this is happening sms becomes erratic (I receive texts multiple times sometimes 20-30 minutes after it was first sent, texts are received in the wrong order, cannot send texts until i restart phone).
Possibly hardware issue?
I had the same problem... could connect to the wireless network only if wireless data was disabled or WIFI was on.
Ordered a replacement which came today, and all is good Seems to be a hardware issue.

I to am having the same problem connecting to data networks. I have had the nexus 4 for about 2 weeks and its been an amazing phone until this morning when I had no data connection in town and around town. My iPhone 4 has 3G connection in the same area, with the same sim card. Ive already looked around the net and found the post to reset the radio but nothing happened. After not having radio or data for about 2 hours my phone finally fixed its self. I have no clue why I lost data connection or how it fixed its self. I will stay posted to see what happens but maybe there is some bad hardware in the device that is just now starting to surface.???
Hi I appear to have the same problem. My phone is able to make calls/text and etc with data off but when data is turned back on it screws around, doesnt connect to the internet, grey outline on service and etc. I'm thinking this is an hardware issue but how would I go and exchange this. One more thing, I bought this brand new from someone, does that matter?

If you want to RMA your phone, you can transfer the ownership by calling Google Play support. You will need the device IMEI and the email address of the original purchaser. Just tell them the phone was gifted to you. After the ownership is transferred, you can begin the RMA process.

When I try to connect to a T-Mo tower for data al I get is an icon in the notification area saying "Sign in to Network" =. When I hit that I am sent to a T-Mo page asking me to sign in. I give it my credentials and press login but nothing happens.
I've talked to T-Mobile and they cannot find anything. They've sent me to Google. Waiting for them to get back to me. In the meantime I figured I'd ask XDA. So, any ideas?
Relevant parameters:
LG Nexus 4
The phone is bone stock Android 4.3
The SIM is new (about 2 months)
I can make calls and text on T-Mobile.
The SIM works in my old Nokia N97 phone and talks to T-Mobile Edge data fine.
The phone connects to ATT HSPA data fine when I put an ATT SIM in it.
The phone connects to data abroad.
Airplane mode is not on.
Data is on.
Roaming is on.
WiFi is off
Airplane mode is off.
I have wiped the phone and started from scratch, no luck.
I have tried in Safe Mode, no luck. (So it's not some odd App interaction)
I have told T-Mobile to kick me off the network and then wiped and restarted, no luck.
I have been through all the APN setting with T-Mobile, all is well.
I have wiped caches, no luck.
TIA
I'd look up the APN details on here for tmobile. Cant find a link at the moment but i know there are a few out there. T-mobile people usually have no idea...
It sounds like something on the carrier's end though. quick search brought up several topics on xda but no real solution.
It has happened to me as well, but my data still works. Sometimes I just reboot it, or put it in airplane mode and it will go away.
Unless u never get data.

this happened toe last night as well, lasted about 3 hours or so. it connected to the towers jist fine, sometimes the signal bars turned blue, sometimes not. but no data flowed through, neither via lte or hspa+. i called tmobile to check if they had an outage, they said no. i had them reset my data connection, but that didnt help. eventually data started flowing via hspa+, then via lte an hour later. i did all the troubleshooting, it wasnt an issue with the phone nor sim card. it was a tmobile issue for sure.
