I bought a Nexus 5 from the US and am using it in India on a vodafone carrier. 2g calls work fine.
3g data does not. When i turn data on, it turns to H - > 3g -> and no signal and the cycle continues. I have tried replacing the sim twice to no avail. Is this a modem problem ? Should I flash to a different one ?

Hmm. Sounds strange. You running any custom software? Have Preferred Network Type on the best selection for your network? Have the correct APNs? Those are usually the main culprits of issues like this.
My nexus kept changing between H and 3g and I couldn't figure out why. Eventually the reason behind it was my preferred network type got changed to 3g instead of LTE. So I would check that first.

So the radio is crashing?
How about doing a *#*#4636#*#* and then selecting menu (3 dots) and do radio selection and then choose EURO frequencies and see if that helps?
Looks like I might have a solution for this, which I will try later in the day. This is definitely an issue with the carrier and not with the phone itself. The carriers themselves do not support the phone, hence you would need to get your sim card activated on a known good phone and then once its activated, use it on the nexus 5. I will confirm this tonight.

The US version has different radio bands than the international version. That could be why you are having issues.
North America (D820) model:
GSM: 850/900/1800/1900 MHz
CDMA: Band Class: 0/1/10
WCDMA: Bands: 1/2/4/5/6/8/19
LTE: Bands: 1/2/4/5/17/19/25/26/41
Rest of World (D821) model:
GSM: 850/900/1800/1900 MHz
WCDMA: Bands: 1/2/4/5/6/8

That switching is intended. The phone idles on UMTS and when data is called it switches to HSPA as indicated by the icons. It's not supported in all T-Mobile markets, but it is on mine and presumably yours.

Hello guys
Any one knows why I get this message not registered on network if I try to make any call whenever I switch to WCDMA only even though I have a signal.
I'm not using AT&T sim card, but I can use it just fine with GSM band.
Thanks
Sounds like network registration failure. Chances are your service doesn't support AT&T 3G/WCDMA bands and when you're trying to force it to WCDMA it won't allow you to register on AT&T's 3G because you don't have their service.
If you're using T-Mobile, for example - you can only register via GSM/EDGE connections as they don't share compatible 3G connections

Sounds not good at all. So because the device is from AT&T I can't use any 3G connection with different carrier other than AT&T
P.s. why do I have a good signal in wcdma connection?
Thanks anyway
Only certain carriers have the WCDMA bands that AT&T uses. AT&T uses 850Mhz and 1900Mhz for WCDMA, so does Rogers in Canada - therefore, if you use Rogers as a service, you can utilize WCDMA no problem.
Now, if you're using T-Mobile here in the U.S. - who uses AWS 1700/2100Mhz for their WCDMA connection - it won't work as it's an entirely different band. There's no fix as this is a hardware limitation until at least AT&T buys T-Mobile officially.
What service are you using anyway? When you say WCDMA signal, what do you mean? Do you have an 'E' by your signal bars or H+?

Hello,
So i've got this nicely unlocked, shiny, G2x. (Running MIUI right now, please don't judge me) Anyways, I'm in Morocco, and am trying to use Maroc Telecom (IAM) which has 3g data (their site even claims HSPA+) and these are the frequencys they use:
GSM 900 / GSM 1800 / UMTS 2100
And copy pasted from the T-Mobile website, the G2x uses:
Quad band GSM (850/900/1800/1900 MHz), Dual band UMTS (1700/2100 MHZ Bands 1 & 4)
To me that looks compatible. Trouble is, i'm getting no data whatsoever, not even 2g, in an area that I know should have at least 3g. I've signed up for the plan correctly, I'm sure of that. And my G2x automatically picked up the APN settings when I first turned it on (and I verified that they are correct) but still not a hint of internet access. This is driving me crazy!! any hints would be greatly appreciated.
Just guessing, but does it think you're roaming. Maybe try enabling data roaming to see if it recognizes the data then.

It wouldn't be roaming if he bought a sim for that system as he says. Probably APN has a typo or not selected. Have to push radio button so it has a green dot to enable the APN. If that doesn't work then contact carrier to reset data on the account. I have had to do that in the past here in Thailand. Have you also tried turning the phone off and on, or doing airplane mode. Sometimes that is needed once.
Thanks for the responses!
Unfortunately, i've tried and double tried all those things, except getting the carrier to reset the data plan. I'll do that next. Now I just have to get through a bunch of menus in French & Arabic
Are you running Market Enabler. It can screw you up royally if you change sim and it was set to fake at boot. I had that on a Nexus One and had to factory reset the phone to get data working again when I changed sim.
Thanks for the advice. I don't think i'm faking my sim - unless that's something that comes with CM07 and I just don't know about it. Also I tried it on stock before flashing with no different result, so i'm pretty sure that's not it. Went to the office of Maroc Telecom, who replaced my sim (but still no luck) and an INWI sim which i'd previously been able to get 2g coverage on now gives me nothing. It is the weirdest thing and I feel stuck. Has anyone actually gotten a g2x to work on any other network?? is there some sort of Tmobile lock which is preventing me because i'm not using a tmobile sim? (And i'm not talking about the phone being 'locked', obviously i've gotten it unlocked, and can make calls just fine, and did have that short spell of 2g data on INWI) Anyways, i'm about ready to throw this very expensive phone out the window, because what is a smartphone without data?? Thanks anyways for your advice.
same, problem.
How can I solve it?
Maybe try to use other broadband?
I use my G2X in Thailand on TOT3G with no problems. They run 3G on Band 1 (2100/1900). Figure out what band it is. There about fifteen different 3G bands in use. Most people don't realize it but 3G radios use two frequency spectrums at the same time. There is an uplink and downlink. For example 2100 Band 1 uses 2100Mhz downlink and a 1900Mhz uplink. Band 4 is 1700Mhz uplink and 2100Mhz downlink. So the 3G radio in the G2X also transmits on 1900Mhz. But the 1900 Band 2 uses 1800Mhz as an uplink, which the 3G radio in the G2X doesn't support. Most companies that say they are on 2100Mhz are referring to Band 1. If they are running Band 1 the G2X definitely supports it. If you have sim unlocked the phone there is nothing preventing you from getting 3G reception on any carrier in the world.
Download "Network" (https://market.android.com/details?id=de.mangelow.network&feature=search_result) from the Android Market and run it. Scroll down to where it says what type of connection you want and make sure "WCDMA preferred" is selected. If the phone somehow got set to "2G only" you will never get 3G reception until you change it. That happened to me once on a Nexus One and took me a while to figure it out.
CM7 and some other custom roms are known to be having connectivity issues. I suggest you flash back to stock and make sure your apn is correct. If your apn is wrong in any way, the connection will be refused by the cell system.

For the what?
Just wanted to give some info I found using QPST(qualcomm software) to see what cell bands are configured for our HTC One M8. I even looked at the Rezound bands as well. As most of you know, verizon didn't carrier lock our phones, so if we switch to global or even GSM network, we can use other carriers GSM SIM cards. Just need to properly configure the APN's of course. Below are the bands that the phone will search for when Global Network is selected. I pulled this configuration from my actual device. The Rezound only was missing Bit 19 & 49 selection, but everything else was selected:
[Bit_00] Band Class 0, A-System
[Bit_01] Band Class 0, B-System
[Bit_02] Band Class 1, all blocks
[Bit_07] GSM DCS 1800 band
[Bit_08] GSM Extended GSM (E-GSM) band
[Bit_09] GSM Primary GSM (P-GSM) band
[Bit_19] GSM 850 band
[Bit_21] GSM PCS 1900 band
[Bit_22] WCDMA Band I - EUROPE JAPAN & CHINA IMT 2100 band
[Bit_23] WCDMA Band II - US PCS 1900 band
[Bit_26] WCDMA Band V - US 850 band
[Bit_49] WCDMA Band VIII - EUROPE & JAPAN 900 band
I'm guessing the reason some of us are having issues on Tmobile is that the AWS bands are missing? Can we enable them somehow?

It could possibly be activated using QPST, but there are other steps to do it. The only issue is that since QPST is the QualComm radio programing, there is potential to lose signal quality or lose all radio functionality. That said, it could also be possible to recover by flashing the original firmware or RUU to recover. I now T-mobile uses 1900 GSM PCS band and AWS 1700 mHZ. There is another program I use to actually enable more bands. The program basically converts the selection of bands to a hexidecimal number to use in QPST software to program the added bands. Again, not sure if the Qualcom chip can use it. There is a WCDMA band selection for Bit (25) IV- US 1700 than could be programed to enable. I used a thread from the Sony Xperia forum to help me use the two programs.

There's a solution for this problem, if you are s-off-ed. I also did the same thing - i selected USA bands and my phone radio died. Just make a nandroid, flash ARHD , go to the same 4636 menu and it will give you another option in band selection - Auto!! Choose auto, then reboot and make sure you have connection with the network. Then restore from nandroid and you're good to go! I will try to find the link to the original thread!

Thanks that was helpful! Somehow I also had recently loaded a Xposed app to show CPU speed on the top bar. I uninstalled that then after two reboots things came back. So odd, but I'm not complaining at this point.
after a google search it seems people have gotten into problems with chaning bands on verizon devices, the above solutions brings the radio back to life. But it certainly doesn't unlock LTE on europe bands.
So i guess its a lost cause, as it must be a hardware limitation
Yeah disappointing that we can't add those

Original thread for unlocking all bands
wow!
good job
was it hard? im afraid...
Hello! I bought recently a SM-G925P Sprint though craiglist. It was google locked and sim locked. I was able to google unlock it and also sim unlock it. Its rooted with unikernel. Sim unlocked using this guide: http://forum.xda-developers.com/spri...sung-t3130294/. Im located in Uruguay.
I thought i was not able to get LTE but thats was not the problem. I realised it gets LTE but it takes A LOT to take LTE signal. Every time i reboot it takes like 20min or more to change from 3G to LTE.
I got the SPC or MSL from the idone app and followed the steps this user said: http://forum.xda-developers.com/show...07&postcount=4. Just disabled the Band26 and Band41 bands and set bands priority to 4 and 2. It seem to get LTE faster
Do you think there is something i can do to get LTE faster? My nexus 5 take signal immediatly. I think it has to be something about the Mobile networks>Network mode option. I must select Automatic to get LTE. If i select GSM / UMTS it only takes 3G. And if select LTE/CDMA i get no signal. Maybe it takes a lot because it searchs for CDMA networks and then LTE ?
Any help would be appreciated. Thanks

Also im getting "Update messages" everytime it boot up:
-Update finilizing
-Update profile The network is preparing your services.
-Error the profile update could not be completed.... Error 6600
Edit: everytime i reboot, disconnect from a wifi network or make a call i get the 3G network and take like 5-30 min to get the LTE.

Hey guys,
So my Nexus 5 stopped working the other day, and I sent it for repairs. It's come back now and I got a new SIM. Airtel 4G here in New Delhi, India. The problem is, it will only show me a 2G connection/no signal at times. I don't know what to do. The SIM works in other phones perfectly well. I've tried going to *#*#4636#*#* and changing to WCDMA only. Doesn't work. What is the alternative solution guys?
The phone was bough in the USA but before it got repaired, 3G worked flawlessly. So at least that should work, if not 4G.
Thanks,
Crazysah
No one has had this problem? Or no one knows a solution?
Hi, Airtel as I see operate in 2G (GSM, EDGE), 3G (HSPA+) and 4G (TD-LTE band 40). But Nexus 5 (USA model) D820 doesn't support TD-LTE (band 40), so for sure you can't connect to 4G. But 2G and 3G should be ok. You can reset network settings and check again.

Yes. 3G should work at least. But it isn't and that's the problem. Before repairing it, it used to work with my mom's Vodafone 3G connection. What's the solution here?
Can you try to restart and after that change to "GSM auto (PRL)" from *#*#4636#*#* menu? Are you tested other device with this SIM in the same location ?
