[Q] No 2g (GSM) reception - Nexus 5 Q&A, Help & Troubleshooting

i know, most of us care about 3g and 4g reception, but my problem is the opposite one.
my Nexus 5 has no reception of 2g (GSM) cells. Already reflashed Stock 4.4.2 image. Still no reception.
Has anyone any other idea what to try before starting RMA?
regards
Bernie

Does your network provide 2g coverage? Mine doesn't. Just thought I'd mention it

Yes it does. Here in the Mountains 2g is often a lifesaver.
Double checked with wifes N4, no Problem on 2g, just lousy download speeds...

Weak LTE pickup

My N5 is not great at picking up LTE service. My AT&T signal is weak at my house and I don't get LTE, although my Galaxy S2 used to connect that way. Not sure if the phone really doesn't see it or if it thinks it's too weak and HSPA would work better.

I have the same issue on T-Mobile. My phone sucks about picking up and using LTE whereas my Nexus 4, a phone that required hacking to get LTE enabled, was a champ. My N4 would remain on LTE all day while in the city regardless of signal strength with no real observable detriment to my battery.
With the Nexus 5, I'm lucky to have it switch to LTE in high signal areas. My Nexus 5 will stay on LTE if I force it to connect using LTE Only (you lose voice with this setting) under the secret dialer menu (*#*#4636#*#*), but if I let the phone decide, it sticks with 3G/HSPA+.
I'm paying for LTE and I want to use it, damn it! LTE at half signal strength is still faster than HSPA+ at full strength for me on T-Mobile.
Actually as I travel along the Ohio Turnpike it is not doing too badly, picking up LTE as we pass near metro areas (Toledo, Cleveland). It is also working great tethering my tablet with Wi-Fi as well.

I'm having the exact same issue here I'm in the Los Angeles area and I have experienced good speeds on LTE up to 23 down and 12 up but one thing I have noticed is my LTE drops a lot in to H. I'm coming from Verizon which always stayed on LTE locked in so I guess I was spoiled. I left verizon because I got sick of them hating on Nexus Phones but man right now I'm hating these LTE drops on AT&T. But I know for a fact that it's a phone problem because when the phones goes from LTE to H I can manually restore the LTE but I can't get it to stay locked. I called them and they're response was it's just the phone switching from tower to tower.

T-mobile LTE N4 vs N5

I just helped my son install the hybrid modem for his Nexus 4 and set up the T-mobile APN for it. I was about to tell him that he would have to go somewhere else to test it since I never get LTE at home, and then boom, the 4G icon shows up on his phone! I checked Network Signal Info and sure enough, it's got an LTE connection with about 6Mbps transfer rate. Sitting right next to him my N5 has only 3G with occasional switches up to HSPA and back, and a very low transfer rate. What gives? I am able to get LTE on the N5 in other areas of town and it works wonderfully, but around my home it is very weak and almost never runs in LTE mode.
Could it be that the N4 is connecting on a different LTE band? If so, why is the N5 not using that band as well? Is there something that can be done for the N5 to tweak it to improve its LTE reception or how it chooses how to connect to available LTE signals?
Both N4 and N5 have 1700 band so it should get perfect HSDPA.
It might be the towers in your area are busy or the signal is weak.
I use straight talk t-mobil and I get HSDPA around 15Mbps and my friend get a little more on LTE here in chicagoland.
Also for people on Straight talk if you want to get LTE att version you need to get a new simcard and change APN and for t-mobil
just get a new simcard and boom you get LTE.
Idk if I'd worry about it. In most places the HSDPA speeds for T-Mobile are the same or better than the LTE speeds you would get. I'm in the far north chicago suburbs and I get LTE and HSDPA downloads at 25mbps. The LTE coverage is still a bit spotty. Its probably only worth it if I you're in a developed urban area. However it is a bit strange that you guys have the same hardware, service and location but different connections. The only thing I can think of is that I've seen some people instruct to setup the apn as fast.tmobile.com. however mine only worked with fast.T-Mobile.com (with the dash). I would also check to confirm that your phone is set to lte preferred (LTE/gsm) and not gsm priority. Those are the only things I can think that I can think of. Hope it helps.

T-Mobile 4G LTE will properly works on fast.t-mobile.com, fast.tmobile.com is not the proper APN (the - matters)
There are just way too many variables. Maybe his modem has better reception, newer sim card, etc.

Fwiw there are other threads where people have reported that the N4 picks up LTE in the same place that an N5 does not. So you are not alone. N4 may have a stronger radio. That would be unfortunate... Never good to see a step backwards on something as important as that.

Good news everyone! I too has having this problem. My Nexus 4 was an LTE champ and then it was a huge let down that my Nexus 5 was treating LTE like it had cooties, but now my Nexus 5 works the way it should. What I did was go to my nearest T-Mobile store and told the representative what was happening. He called tech support and they ended up doing some sort of reset to my account. I also had questions about my SIM card and felt that it could have been at fault. He offered to switch it out to the new ISIS SIM and as soon as my phone booted up, it was on LTE. Since then, it has behaved like my Nexus 4. I am even in my office where the Nexus 5 wasn't picking up LTE, but my Nexus 4 was, and it is on LTE at the moment.
I am not sure if the reset that tech support did solved the problem or the new SIM, but I would definately give that a try--it didn't cost me anything and now I am happy with my Nexus 5. Good luck!
In my experience my N4 has slightly better signal pickup than my N5.
The real reason is probably differences in the radios' priority algorithms. Set your N5 to LTE-only and see what happens, I imagine you'll get LTE.

Did you not get LTE at all, or really poor LTE signal/speed?

I would get LTE eventually only to lose it when it reached 2 bars or lower. It was really weird. I would be in areas where one would get 5 bars of LTE and the phone would sit on HSPA until I would show the phone it was on LTE by switching to LTE Only under the secret dialer menu and then back to GSM/LTE (if you use LTE only, you will lose voice). Then it would hold LTE until it reached 1-2 bars and then go back to HSPA.
I hope this helps.
I am seeing strange readings of signal strength. I see a 10+ db difference between what is reported in the phone status and an app like rootmetrics.
I don't know which one is misrepresenting the signal strength but it seems the roometrics is more accurate because my nexus 4 the signal strength is roughly the same on lte.
Can anyone else confirm?

[Q] HSPA Fallback

Hi everyone,
I was looking around and I read that the Nexus is suppose to fallback to HSPA when the LTE signal is weak or non-existent.
I was curious as to when the phone actually considers the LTE signal weak. In my room, I only get 1 bar on LTE (~115 dBm), sometimes losing the signal completely, however I have never actually seen it fallback to HSPA.
So my question is, when does the phone automatically switch from LTE to HSPA?
Thanks in advance!
Current setting on my phone:
LTE (Recommended) is selected as the "Preferred network type"
[LTE/GSM auto (PRL) in the hidden menu]
Yes it will automatically switch when you not in a LTE area.. Its not based on signal strength.. Its based on your area and the area without Lte must have hspa to work or it will switch to 3g or Edge if hspa is unavailable...

As in previous reply, it only falls back if there is no signal. Sometimes signals are weak and connection drop. Your phone tries to connect back to LTE. Since LTE signals are still in the air, it wouldn't switch to HSPA. If you think you will benefit from HSPA compared to LTE, you can manually change it.

Hey, thanks for the quick reply.
I guess now my question is, how long will the phone wait before it gives up on looking for a LTE signal and switch to HSPA?
I initially thought that the phone would fall back to HSPA if the LTE signal is too weak.
Thanks in advance!

[Q] Is the cell reception in Canada okay?

Hey!
I have an invite and I'm close to buying this phone today to use on the Fido network in Canada (Toronto and Waterloo Ontario areas). I've been hearing that there are some reception issues with this phone. Does anyone have the OPO in these areas and can you comment on this? Should I buy something else instead?
I'm living nearby border of Ontario and Quebec, some of these places have poor network reception on my old Hercules S2x but don't with my OPO! In larger towns, everything is A1.. I'm on Telus network btw
I am on rogers in the GTA, no issues with cell reception on the OnePlus, LTE works.
With Rogers in Alberta. No reception issues whatsoever. Those who have reception issues probably live where reception isn't that great to begin with
Sent From Lollipopified Bacon Goodness!
Got 7 OPOs in the Toronto area. All running latest 44S modem and it's fine.
All 4 bars LTE and sometimes H+. No drop in signal.
Awesome. Thanks! I pulled the trigger on the purchase. Glad to know it should work without any problems.

nexus 5 cellular data problem

Dear XDA community
I have a D821 device and since I started using mobile data I noticed that I was having a very unusual issue. I was getting only 2G and 4G signals with greek carrier COSMOTE GR & VODAFONE GR. Max signal on cosmote was Edge and when on 4G coverage 4G. On Vodafone I'm getting GPRS only. Any member had any similar issue and any solution to Fix it? Can it be a software issue or hardware?

I think that this is just about coverage and signal strenght of your providers.

My carrier works just fine on my z1 compact with hsdpa+ and 3G so that's what concerning me
@VER5Uz
Xperia has better radio then our devices. My son use XperiaU and he get better signal then me in areas with low coverage. Also my wifes N4 is better in this.

So it's just phones antenna not receiving good. Damn I'm on that issue over 2 months and I'm getting so mad having so slow speeds. Is there a utility to confirm if the antenna is not malfunctioning
Buys an LG device, gets crappy LG antenna lol
Change modems and see if it helps.
