Hi,
I have a Samsung Nexus S on Orange UK. I have noticed recently that I am not connecting on 3G and only GPRS.
I thought it may have been down to the ROM so I restored the stock firmware but that still doesn't work. Going to the testing menu (*#*#3646#*#*) confirms its on GPRS and if I set it to WCDMA Only, it attempts to connect and then says disconnected.
I have checked the SIM in a USB Dongle and it works fine so I don't think its reception or sim card related.
Is there any way to debug this on the phone? Could it be hardware (does GPRS use the same hardware or are they seperate radio chips).

Did you try to use a different radio? Sometime it is radio problem.

I bought mine on contract through cpw in December on a vodafone contract but not branded and it's unlocked and have no issues regarding this. All gsm phones are compatible with the UK networks (I think) so probably not a hardware problem. U should try another network Sim in your phone and see how that behaves.
If u don't get 3g then contact orange maybe it's their fault. Or could be you're not in a 3g area.

Thanks for the replies.
The phone used to work on 3G - The SIM has not changed and putting the SIM in a Data dongle confirms its working so not a network issue or reception.
I have tried various radios just in case it was that, but again still no 3G.
I have tried everything I can think of which is why I was thinking it was possibly a hardware fault with the phone?
Mine was through CPW unlocked, which radio are you using leerobson99?
Xxkf1 just updated to 2.3.6 today, stock unrooted.

Try a hard reset this may work for you.

still could be your service provider though rather than the actual phone.

bought a nexus s with a properly smashed screen off ebay and replaced it with a new one. when i insert sim card and search for a network it says cannot connect to network please try later. does this mean its been imie blocked?? bit pissed off to be fair but hey ho always a gamble when you get off ebay
I believe that you would still have to activate that with carrier and if it's blocked they can tell you

it just registered on network then it cut off again,could it be the antenna? anyone know the location of the antenna on the nexus s?
when connected to network calls and texts dont work but 3g internet does. help appriciated
This sounds like a job for Odin. Get the newest factory image from here and be sure you flash everything....rom, kernel and radio, especially! This is the best way to see if it's a firmware or hardware issue. If it still happens after a factory flash you'll know it's hardware related.
My Nexus 5 frequently loses mobile data connectivity. Its been happening since I purchased it, but the frequency with which it happens has increased since I flashed the M1 snapshot of CM. I've since flashed the second snapshot from early January, but it has not made any difference.
This is the same sim card that ive used with my nexus 4 and my htc one without any problems, and I've made no changes in my wireless carrier.
Does anyone have any thoughts as to why this happens?
Try a different,maybe older, radio. If that doesn't help go back to stock and see if it persists.

Flash the Nexus factory image. If that fixes it, its a problem on CM's side

hi.
i was this problem too, not exaactly the same, but somehow similar. I have 3g connection, the signal bar shows H and somtimes 3G, but the speed is freaking slow, worse than 2g. Initially I thought its something wrong with my phone, been changing ROMS to see if it is the issue, but no. Then I flash the latest baseband / radio, and still doesnt help.
Be reminded I am on 4G plan, but never had any 4g network ( it is not because i'm not in an area with no 4g network )
I was very frustrated and emo at the same time, thinking of RMA the phone, thought it is the radio chip problem.
but then... I called my telco, asking why I'm experiencing slow connection and bla bla, and I don't have 4g network. They keep saying my network is working perfectly, and running normally, I requested them to reset my network connection. They agreed and asked me to turn off the phone for a few minutes then they reset the network for me.
After that, everything is running perfectly.
This was 2 days ago. And guess what, I don't have any 4g connections now again. Stupid telco, I'm going to call them later when i'm free. grrr.
but please make a call to your telco and ask them.
Hope that helps
I've been happily using an HTC MT4G Slide/Doubleshot I got on Ebay since December (I'm in Canada, using it with Wind Mobile, AWG 3G bands). Last Sunday my phone suddenly started showing "No Signal" for the cellular connection (wifi still works just fine), even though I had full signal bars, and I was unable to complete calls, even the *611 carrier service calls. With the Wifi turned off, I noticed I was still receiving emails, oddly enough, even though I could not register on my network. My SIM was working fine in other phones, and a SIM from another carrier (GSM 2G only) worked just fine. I tried a new SIM from my carrier, no luck, same thing.
I know AWS splits its up/downlinks between the 2 sets of bands it uses (1700MHz for up, 2100MHz for down), so I'm guessing something strange happened to selectively knock out the up bands only. But what? My phone is on EmmanuelU's KitKatDS 1.3, but the only unusual thing I could think of software wise was that I had recently updated Xposed framework to the latest version. I though maybe that did something weird to the baseband firmware, so I restored the original stock Gingerbread ROM via ClockworkMod - no change. I applied the available OTA updates from T-Mo - nothing. Re-flashed KitKatDS & restored by current set-up - nothing.
I'm completely stumped and seriously starting to worry it's some freak hardware thing. Anyone here ever experience something like this?
Thanks for any of your thoughts!
Never seen this myself before, check your apns would be my next step. Maybe try *#*#4636#*#* from the dialer and see if what it says there too. But mostly I'm stumped

(well, everything short of new SIM card)
The situation:
-bought a 32GB N5 from a guy
-I'm on Rogers in Canada
-on Lollipop
-cannot get LTE, only 3G and 4G (H)
-APN is correct
-checked everything in *#*#4636#*#*
-cleared cache
-reflashed facotry image
-tried Cataclysm
SOMETIMES, I'll get "LTE", but it's a phantom - there actually isn't a connection at all.
I've swapped phones many times before; never had an issue. I read in threads someone saying that on AT&T that you need to register IMEI with them to get new device working with LTE. I never had to before, but called Rogers to check if this is something they've started doing.....no.
Under device model, it doesn't say either 820 or 821. It says "Nexus 5"
I started thinking that I stupidly bought the international model off the guy, but then when i was in fastboot mode I saw that it did say 820.
So.............I'm stumped, puzzled and pissed.
Does anyone, ANYONE have suggestions or ideas? Many thanks!
Sanity check but worth investigating:
- Definitely have LTE coverage in your area? I assume other phones around you connect to same LTE network no problem
- Does the SIM connect to LTE in another known working phone?

Yep, coming from my old phone. Have always had coverage in all the areas I've been with this new phone. LTE SIM, LTE area...it SHOULD work, but is not.
Try a new sim at the store, if it doesn't work return it on the spot. No harm, worth a try
Does 3g work? What bands does your carrier run in your area? You might try the diag LTE screen (requires root, there's an app from the Play Store) and see what band it sees. Also have you tried doing a scan of which carriers are available?

3G and 4G work.
I went to Rogers store and got a new SIM. No change.
Same thing...
I'm just posting to let you know I've had EXACTLY the same problem..
Mine occurred after I smashed the screen and sent it away to a company to be repaired. My N5 came back with a new screen, so immediately I upgraded to lollipop...
Then the LTE stopped working. Occasionally the device would say it was connected to 4G but, like you, it didn't work when it showed this. I tried everything, flashing, checking access points, flashing different radios...but nothing worked.
Now I can't work out if the repair company had somehow damaged the 4G antenna when they were fixing the screen. So I sent it back to be repaired (again)
Now i've got it back. 4G works but it has lost a lot of speed. Where I was getting 25mb/sec on average, I now get 10 max.
I've e-mailed the repair centre to find out what they did, but honestly, I've given up a bit now...
Wait, you upgraded to Lollipop? You realize that they included a new radio right? Try reverting modems.

Hello everybody,
I am using a Nexus 5 for a full year now and I noticed from the beginning that I never can get 3G signal, but when I am in the nearest city I van get 4G/LTE. Last week I wanted tot know more about it so I inserted my sim into another phone and immediately I had full 3G connection. So I updated to 5.1.0 with the new radio for 5.1.0 and I still couldn't get 3G. When I googled for 3g coverance I noticed I shoud've get full 3G. however only 2G and 4G works but the problem is that there is no 4G coverance in my hometown so I am stuck at the slow 2G. I'm in the netherlands and I already tried all options in *#*#4636*#*# but I still dont get 3G. also my apn settings are correct. so my last hope is to ask here if anyone knows what to do. I'll include a picture of my baseband version etc.

If it doesn't work after clean flashing factory images and trying different radio versions, it might be a hardware problem.
It's sad because I don't have any warranty anymore because I've opened the device up to replace the screen myself. Do I need to change the whole motherboard?
