I have had my SGS4 since June running CM with no issues connecting to LTE, but I recently tried PA android and could only connect to H+ as the fastest network connection and Network Mode defaulted to WCDMA preferred and could get no network connection at all if I changed from that. I tried going back to CM and still had the same issue. Reflashed stock using Odin and have since tried Shostock and CM again, but still cannot connect to LTE. I also tried my sim in my Nokia Lumia and get LTE on that so there doesn't seem to be an issue with my plan or sim card.
Does anyone have any ideas on how to fix this?
Sorry if this is a silly question, but in the interests of ruling out all possibilities: Are you sure that it's the actual connection, and not just the icons? Maybe you're used to seeing a 4G/LTE icon that isn't used in another ROM.
It wouldn't really make sense if you went back to CM and that issue persists, unless an icon setting is preventing you from seeing the icon. It might be worth checking the settings, because as I recall there are plenty of ways to customise your icon area.

I am sure it is LTE and not an icon issue, Before flashing PA I was getting 30-40mbps and now the highest data speed I can get it 3-6mbps. If I set the network mode to GSM/WCDMA/LTE (which is what it has always defaulted to before) I cannot connect to a the AT&T network until I set it back to WCDMA preferred. As I mentioned in my previous post it is only this phone, with the Windows Phone I tested using the sim worked fine on LTE. Also as I mentioned this happens on several roms, and has continued after a complete reset to the factory rom using Odin.

Good evening all,
Hopefully someone can answer my question.
Sunday I took a road trip. I noticed that my phone had no service. In the past when I left the t-mobile area my g1 would automatically connect to whatever network was available and the roam indicator would show up.
I tried to manually connect to at&t through the network operators menu. My phone said "Your sim card does not allow a connection to this network.".
I have a rooted g1 running the official t-mobile 1.6 rom. Is this a problem with my rom or my phone or the network. I've tried searching and I haven't found much of a solution yet.
I am in the usa. A lot of the google search results I got were from Europe.
might not have been a ROM issue; just a bug...
Did you reboot or force radio off then back on?
I have the same problem and yet no luck to resolve this.

I did reboot and enable/disable airplane mode.
Today I switched to the Cyanogen Rom. I'll see if that fixes the problem. I tried to manually switch to at&t, but it still says that the sim card does not allow that. I am in the t-mobile coverage area; t-mobile probably does not allow the use of a different network when their network is available. I'd like to test it out to see if roaming works now, but I'm not taking a drive out to the countryside just to see how my phone works.
I guess this one might be hard for me to test because I am rarely out the the t-mobile coverage area.
Hey. I have an HTC Magic (32A) from Rogers. I followed the guide on the CM wiki for rooting my phone and installing CM 6.1.0. The installation and such went without a hitch; it's working fine, except my data connection no longer works. WiFi works perfectly fine, though. It's just a shame because I'm now paying for a data plan that I can't use.
I read around here that it's usually an issue with the APN info, but I triple-checked it and it seems all fine and dandy. The "Data connection" option is also checked, as it should be.
The only thing I can think of at this point is the ridiculous 911 debacle, but the Rogers waiver form for reactivating data says my IMEI is invalid -- this seems like a very common issue, but I'm a bit weary of calling tech support since I have a rooted phone.
If it's even possible at this point, I wouldn't mind even reverting back to my stock 2.1 state, except I didn't make any backups with nandroid first. Any help would be appreciated. Here's my version stuff:
HBOOT-1.33.2010
RADIO-3.22.20.17
Have you tried popping your sim card into another 3G capable phone, and see if it can manage any 3G traffic?
If so, then it is not a provider / data enable issue, but rather a phone issue.
If you installed CM, then your APN should have been set automatically (CM comes with a big list). If you messed with the APN and saved it, you might wanna check it a 4th time
Have you tried the 2g/3g toggle button in the power widget that comes with CM?
Have you tried the settings of the power widget that comes with CM, where you can configure the toggle options for 2g/3g?
Do you even have normal "g" (GPRS)?
Do you live in a concrete underground bunker? Have you got good enough signal for data traffic?
Data service enable from your network provider is usually to the SIM, and not to the phone (where you IMEI resides).
I think if they block the phone based on IMEI (or don't recognize your IMEI), then you will have no connectivity (both data and voice/txt).
Thanks for the reply!
I tried putting the SIM card into another phone just now (a Nexus One, unrooted, stock ROM), and it's the same thing: voice/text works but no data.
I've had no luck with the APN list from CM. I tried another list I found on the internet somewhere but that didn't work either. I've since reset it back to the CM default.
Tried the 2G/3G toggling, didn't work.
I've never even seen the data icon that shows 3G or regular G. Is there a better way to check if I have a GPRS connection?
I've tried it at multiple altitudes. Right now I'm sitting in an office and I've got all four bars on my signal.
My uncle happens to work for Rogers; I asked him about it and he said he'll send me a list of instructions on what to do, in case the problem is indeed on Rogers' end. If it works then I'll post it here for y'all.
Hi All,
Not quite sure what happened here.. Upgraded to latest nscollab yesterday, everything was working fine. Decided to try the "Antennas" app to see if it'd show where the towers are near me, switched to 2g mode, played around with it a bit, switched off 2g mode and now my phone does not see telus at all. When I go into search networks, telus simply doesn't show up and my phone stays in emergency mode.
It sees rogers fine and is able to connect to rogers with a friend's rogers sim. I've tried my telus im in other phones and it works fine, other people's telus sims in my phone don't work either.
I've tried reverting to an earlier backup as well as going back to a stock backup. I've also tried reflashing both the kb1 and kb3 radios, no luck.
Anyone know what might be the issue here?
both Telus / Bell do not have 2G
they only have 3G, as in the VOICE only works via 3G
it was the same using the SGS i9000
Did the rogers SIM work on 2G (Edge) only? I am guessing Rogers and Fido will work, but only on 2G
Same happened to me, on Fido, my phone could no longer connect to 3G...Only 2G after playing with settings. I returned the phone
The reason why Telus-Bell SIM would not work at all at this point is that they only support 3G...
That makes sense, but i don't have it set to 2g mode anymore. It should be seeing 3g just fine.

Just tried that, nothing. I think that's the same as a wipe data in recovery?
I've tried:
- Reverting back to a stock backup
- Reverting to an earlier working backup
- Doing a factory reset on both of the above
- Reflashing the radio on both

This just happened to me, I switched to 2G and got nothing but com.android.phone quit errors, now I can't get back on 3G. Flashed radios, data wipe, everything... wtf... it's back to stock now and still can't get on Telus... double wtf...
Christ... finally got it... my head hurts from all this reading
For some reason it was on the wrong band. Do this in dialer... *#*#4636#*#*, phone information, menu, select radio-band, USA, and should work make sure its on WCDMA preferred as well under phone information

I had the same issue when in Canada, and forgot I had the band set to Europe (my region).
I set it to Automatic detect, i know catching signal will take longer. But then I dont forget

i had the same problem since may 14th (sat), thanks for the fix!!!!!!!
Same thing happened here, same solution. Glad you stumbled on it too!
As the title says, had the same problem on my Nexus S (running on Bell), I believe manually switching the 2g/3g toggle in cyanogenmod rom accidentally is what set it off.
Glad you found the solution!! Was maddening for me; knew there must be a way to fix through the UI, but until I fond it, phone was a wifi mp3 player :/
I've not had a 3G/HSPA signal on my N4 for a while now. Trouble is I don't know exactly when it happened as I'm generally on either WiFi at home or at work, where I know I can only get Edge.
I've tried the usual check the APN, *#*#4636#*#* and nothing's jumping out at me (if I tell it to use WCDMA only I get no signal at all).
I'm wondering if it was the 4.2.2 udpate and wonder if I've got the wrong radio - so the question is does anyone know what radio I should have on my N4? I'm in the UK on Vodafone, but I got the phone from the Play Store.
I've tried searching but the N4 seems to have had so many signal issues it's difficult to sift out the relevant stuff
I'm not rooted but I'm happy to do it if needed. Already tried a factory reset so nothing to lose!
Cheers,
Dave
have you tried a different sim card? thete isnt a specific radio per region, so thats not a problem.

Yeah, sorry, forgot to say. I tried the wife's SIM (different operator) and same issue, only got a 2G signal.
I was thinking it might have been an issue when they updated it to remove the LTE "feature"
Even i have the same problem . I am from India and also have tried a couple of sim card . Im not able to get 3g signal at all . Anyone pls help....
i have the same issue solved whit RMA my first nexus 4 was defective, my new nexus 4 changed in warranty now works well
3G/HSPA networks
participles ipntsly
I started having the same issue today in Atlanta. Had another T-Mobile HSPA phone sitting next to mine with 4 bars while I was on Edge. My N4 is < 1 week old and seemed to be OK but now I can't get it on anything other than Edge.
I've checked my APN settings, reset the radio, turned data on/off and reset the phone with no luck.
Any advice?
Update: Just got mine working, here is what I did.
Wasted 20 mins talking to Google and T-Mobile. (I don't recommend this step.)
Type in *#*#4636#*#*
Scroll down and change 'WCDMA Preferred' to 'WCDMA Only'. At this point my bars switched from Edge to HSPA.
Now, undo the change and put it back on WCDMA Preferred. Make sure it still has a 3G or an H next to your bars.
Exit and enjoy the fast phone.

This worked for me.. thanks
I am having the exact same problem as Dave. My n4 has just stopped connecting to WCDMA (H).
I have tried re entering my APN's, Turning on/off mobile network, Airplane mode, rebooting and removing the SIM. From the test menu I have tried WCDMA only but I lose my signal completely and go to emergency calls only. If I use either GSM only or WCDMA preferred I can get a 2G connection but nothing more and when on WCDMA preferred it can lose connection completely as well.
I am also with Vodafone UK.
solution for this
Guys....even I had the same problem.....but was able to solve it.....
Go to settings >apps>all >Google framework services in this disable it and clear data and again enable it....
Enjoy 3g once again ....it worked for me

Thank you! A few seconds after doing this my N4 connected to 3G!
I have tried what solutions were posted here but everytime I switch from 2G to 3G in the menu I lose signal on my phone..

I tried this as soon as I put WCDMA preferred I lose signal, I have tried doing this in several locations as I live in the country, tried at my school where my friends get H+ and I still lose connection. tried going back to stock still the same issue
Can someone fixed this problem? "WCDMA only" mode make my N4 lost signal.

Getting bars on 'GSM only'
I have got the same issue on my Nexus 4, and I still don't understand how it happened in the first place. I updated a bunch of apps before going to bed and remember waking up to no signals on my phone.
Currently I only receive signal when I go *#*#4636#*#* and set it to 'GSM only'. Any other configuration (WCDMA preferred, WCDMA only, etc) results in loss of signal.
I have tried the following with no luck:
1) Restored Factory Settings
2) Installed an older version of android
3) Flashed multiple radios
4) Steps listed on this thread
Can anyone help me out with this?
Thanks
I have modded my phone a lot and I think one of my mods may have messed up the search for my carrier after I reboot.
#
The problem:
After I reboot my phone it tells me that I have no carrier selected in the system tray. I click on that notification in the system tray. It takes me to the Network operators screen under settings. Then after about a minute it shows all the operators in the area and I need to select mine.
Possible reason:
When I first got my nexus 4 I thought I could activate LTE. I did activate it but it didnt connect to LTE. After thinking that I didn't activate it properly I tried a series of hacks to try and get lte to work. I tried different radios that supported lte. I tried using *#*#info#*#* from the dialer and changed preferred network type to lte only. Since then I have switched it to GSM auto (prl) since that is the only one my carrier will support.
I think in one of the hacks that I did it screwed up the ability to remember the carrier that I had before the last reboot. I have tried different roms with no luck. Currently I use crDroid. I have updated to the newest version which is currently build16. Is there any thoughts on what I can do to fix this.
I don't reboot my phone often but it's annoying when I reboot to have to fiddle with the phone for over a minute just to get a signal. Even if there was some way to search for carrier quicker I would be happy.
Anyone know how I might be able to fix these issues?
