[Q] Signalstrength and mobile internet connection issues - HTC One SV

I often have issues with my signal being at 1 or 2 bars where friends of mine (Galaxy S3 and iPhone 4, but same operator) have like 4 or 5 bars. Sometimes people cant even call me even though my phone shows 1 bar of signal.
Buts thats not the worst thing. My mobile internet connection seems to not work EVERYTIME I'm in some kind of tunnel, sometimes even in normal houses. It shows that it tries to get information (arrow up and down) but it doesn't (it even switches from H to 3G, which doesnt even make sense). In the end it tells me the networks not working.
Does anybody have similar issues?

Some boost mobile user reported similar behaviour.

I've flashed the ICS radio and signal is much stronger. While running the jb update I would have full bars and still get 'bad connection please turn on WiFi to connect to the internet' 4g full signal would do the same thing. Until I flashed ICS radio of course.

Edit. Probably the network, looks like jb radio is the same one, weird though my signal is much stronger now. Must have been a placebo, + the network being 'optimized'
Edit. Can any one verify the boost mobile jb radio? 'its the number under settings next to baseband'
Mine is 1.12.50.0516

I just got my replacement phone. Let's see if this One SV has the same problems. If so, I'll tell them to give me a different phone, I can't use it like that. I'll tell you guys.

I got a new one. It's a non LTE though. But it works way better now. Driving through tunnels makes my mobile Internet disconnect for a second now, but I guess that's pretty normal. Before it didn't work at all in tunnels. Maybe it had to do something with the LTE variant.
Gotta check if the phone signal got stronger too.
By the way I'm writing this while being in the subway station.

My LTE SV has roughly the same reception as my old phone, the Desire, which has always had great reception for me. So in your case it must have been either a defective terminal or maybe some weird software issue.
It's a shame, though, that they've replaced your SV with a non-LTE one. You did pay for the LTE version, that's what they should've replaced it with.

Well, something is still not right with this phone. Even though my mobile internet is working as intended now, I still have big connection issues. Sometimes (at least 5-10 per week) I lose my signal completely, which shouldn't be too much of a problem if it lasted for like 10 seconds or so, but it doesn't reconnect on its own. I have to restart my phone every time. People often can't call me for hours because I don't notice that it lost its signal once again.
I will call them and tell them I want a different phone as I'm still paying for it. I can't use this one anymore or at least not for my job.

Well, now that's weird. I mean OK, you might get one bad terminal, but to have it replaced and still have the same issues...?
It might be that your radio/ROM isn't compatible with the network, or maybe you have a bad SIM card. Try and replace the SIM, see what happens.
I live in a bad signal area. I usually get 1-2/5 bars on WCDMA and 3-4/5 GSM bars. Sometimes when the phone switches connections it'll take 2-5 seconds to do so, but i've never had it remain offline etc.
Could you please tell us where you're from/what operator you're subscribed to?

I'm from germany and my operator is o2. I contacted them again. They told me they can only send me another replacement phone, which wont change anything for sure.
My problem really isnt that it doesnt have signal for a short time period. My problem is that it stays like that for hours!

Please stop quoting the post you're answering to if said post is right above yours. It clutters up the forum.
Right then. So ask for a LTE replacement - that's what you've paid for, that's what they should give you, and see if the problem persists. If it does, use the phone without an SD card for a few days, try not to install any „toggle” software (like 2g/3g toggle widgets etc.) and replace your SIM card (it should either be free or cost you some 2 EUR - that's what Vodafone charges here in RO). If the problem still persists, it must be a network issue.
If you have a few minutes, try this: Settings -> Mobile Data -> Network Operators -> Search Networks, give the phone a few minutes to look for networks, then when it displays the network list, tap on yours and allow it to register. See if this changes anything.

Sorry sir. I'm just pressing that reply button. Didn't know about the one under it.
I just found out something pretty retarded. I went for the network settings and chose the network mode "GSM/WCDMA" instead of "GSM/WCDMA/LTE" and it instantly jumped to 5 bars from 1. It's the fricking LTE network.
By the way i made a mistake. it was a LTE version replacement from the beginning.

Yupp, thats what i always do: let the phone always work in the best available network (set by me to GSM Only).
This Network is pretty stable at my place and its also battery saving because it don't search/switch for another net.

Well that's quite crappy though. I didn't buy a LTE phone and a contract that allows me to use it, just to find out that it doesnt work as intended.
God I hate it.
I told them that this is the problem and they're just sending me a new sim card. Don't really expect this to help, but let' try out and afterwards I'll just contact them again.
At least the phones stable now...

Well, it's not the phone's fault. It's the operator's fault. Their LTE network is not developed enough. You should be happy, though. Vodafone Romania does advertise LTE, but the coverage is somewhere near 0.01% of the country (mostly near Vodafone shops or by the seaside). So where i live i don't even get LTE. And i live in the capitol. :laugh:

Thats what i think. LTE is far away from stable and everywhere available.
Near to me is a village, where you can't use a mobile phone, because there is NO network at all, lol.

What?! In DE? I thought that only happened in the East!

Yupp, in the middle of "DE"...
Lol, don't wanna live in this village. Many jokes and so, you can imagine

My connection is crazy good. Better than WiFi..... I'm loving it.

russellvone, you're lucky.
In the area I'm in a bunch of Boost customers had serious signal strength issues starting last week, and data feels like it's been throttled to 2g/EDGE while we all get "4G" on our status bars.
Service feels like it's been declining, and I've only been with them since June of this year.
PRL updates did nothing.
I used Tmobile prepaid for my personal phone since the Nexus S launched, then a Galaxy Nexus.
The only reason why I didn't get a Nexus 4 was that I thought I was missing out on something without LTE.
I got the SV for free, so I didn't exactly choose Boost.
I just needed something to hold me over a few months.
Now, I won't care if the Nexus 5 has LTE or not, I'm buying one and going back to Tmo.
The SV is fine, the service.....that makes it or breaks it for me.

[Q] Desire s stuck on gsm only

Hi there,
Hopefully someone can help because my brain is melting here. Basically I spoke to orange customer services the other day because of totally poor signal. He told me to switch to GSM only, which was fine and I know it can improve your phone signal. The thing is, it's now stuck on there, whenever I try to change it to WCDMA it automatically switches back to GSM?
Any body got any ideas?
Cheers

I feel your pain. I am also a long-suffering Orange customer. Everything was fine until they climb into bed with T-Mobile. Since then my signal has been so erratic I simply can't trust things like Google Maps to work as navigation. Orange have left me stranded twice bombing out the 3G just as I need it to get home.
Anyway, how exactly did you switch to GSM only? There are a couple of ways of doing it.
Menu> Settings> Wireless & Networks> Mobile Networks> Network Mode = GSM/WCDMA auto.
I suspect it was this one. If this is the method that is changing back to GSM, then try this one;
Open you dialer, and dial *#*#4636#*#*
This will open a hidden testing menu, from this select 'Phone Information'
Scroll to the bottom and see what the 'Set Preferred network type:' is set to.
Mine works well with both GSM auto (PRL) and GSM/CDMA auto (PRL)
See if selecting one of these helps.
Let me know how this goes.
Hiya mate,
Yeah I gave that a try earlier. It seems I have to either have a good phone signal or crap data and vice versa? Pain in the ass. Orange told me that it was because of a faulty telephone mast in my area that has been off since last week. Can't see that being right to be honest, since my signal has been ****e since I first got it in April. Thing is, my sister was having the same problem with poor signal, and she wrote to some higher up person at orange to tell them about it. It ended up with her getting out her 2 year contract, bonus! I'm just going to ring and keep complaining and then write to this person my self, and hopefully I can get out of it my self. Orange is the worst network I have been on!
Cheers for your reply
I might give that a try. I still have a year left, but would love to jump ship and move back to Vodafone. I only went with Orange as my girlfriend was on Orange and magic numbers meant free calls. She then went and screwed things up by moving in! Now I don't need to ring her so much! (facepalm)
My housing estate has a dirty great big cell tower mast at the top of it. My fillings could receive a text message. But even with max strength signal still the 3G is off and on so erratically it's not worth using. They keep telling me that "the cell tower in my area is being worked on" too. That's been their excuse since February.
I have no idea I'm afraid why your phone wont stay on a WCDMA setting however. How are your APN settings? Mine once roamed to T-Mobile without me noticing and would only do 2G.
Yeah my girlfriend is my magic number too, and I live with her as well.. Doesn't make a great deal of sense really does it?
I think you may be on to something with that tmobile thing. Does tmobile allow wcdma?

When I used to do a manual scan for other Networks the following would show up;
Orange
Orange 3G
T-Mobile
T-Mobile 3G
If I try to connect to T-Mobile 3G it wont let me. The one that is just 'T-Mobile' doesn't have anything more than 2G. What happened was my Orange signal dropped out, so it jumped onto the 'T-Mobile' one without me noticing. It then didn't go back to the Orange 3G when I got home.
I just tried it again and got;
Orange
T-Mobile UK
The 2G/3G variants seem to have been dropped and merged into a single provider for each network. I can connect to T-Mobile but still only seem to get 2G.
See which one your connected to. It might be that although we are allowed to use T-Mobile for calls/texts the deal doesn't include 3G.

Yip, that's exactly it mate. I go on tmobile and I can get only 2g, I connect to orange and it let's me have 3G. It jumps between the two networks, and as I have poor orange signal all the time it auto jumps to tmobile! So basically it looks like I'm stuck to 2g if I want to actually speak to anyone! At least now I know what the problem is, but it still doesn't make me feel any better about having to make the choice, and having to constantly check which network I'm on before knowing why I'm getting either poor 2g or poor phone signal. What a headache!
Cheers for your help, much appreciated!

Lately, I've noticed some **** with o2 as well which as I previously recall always had good service, since I been with them for as far as I can remember. I'll have full 2G signal, and randomly the data will shut off. Sometimes for a few minutes, sometimes for hours. But the phone signal remains on full... it's weird. And 3G coverage seems to be getting worse instead of better. None of this makes sense either since in March o2 apparently rolled out 900 Mhz 3G across most major UK cities, meaning 3G service on a 2G band, meaning much better 3G service in areas where only 2G service was previously good. I ain't seen **** all of an improvement, like I said it seems to be going the opposite way.
UK used to be ahead of the game when it came to cell networks, it seems most other countries have not only caught up, but jumped miles ahead. 4G is pretty standard in the US now, and they were so far behind in cell networks only a few years ago.

[Q] Signal drop/No service

Just wondering if any one else gets this, sometimes my signal just drops out and I get no service.
Then it comes back it does not happen all the time, I live in a big city Leeds infact so signal is quite strong.
Just wondering if it could be a fault with the phone?
Thanks
I've noticed it happens to me too.

It is definitely possible.
I'm on AT&T and have the correct APN settings and have called AT&T with my IMEI. I have significantly worse signal than with my HTC One X. I am not comparing bars to bars, but rather where the signal drops completely. In places where I had low signal but still connected I now have nothing.
Straight talk using at&t Sim and notice radio drops..

T-Mobile on stock ROM i had my first signal drops.
I was fine (or at least never noticed them) from the time i got my phone (day one) without any drops here in orlando.
Drove over to Tampa/Venice Beach area this past weekend and noticed some drops. Had about 6 drops according to my battery stats in 2 days. i had good to excellent coverage the entire time except when it would drop comlpetely (outline of signal bars)
would connect in a couple seconds, but i noticed over night, it would drop for a pretty large amount of time (like 10-15 minutes at a time.)
Mmm defo seems like were all having the same issues, wonder what it could be
Sent from my Nexus 5 using Tapatalk
I had this issue too, and here's how I fixed it:
By default LTE is enabled, meaning the phone will periodically scan for a LTE network. If you're in a big city, you're likely to find one. Your phone will attempt to connect. However, it fails, meaning it will have to rescan the HSPA bands to connect back. That results in a few seconds of no service. Why can't it connect to LTE? Because by default, the APN is not the LTE APN, for Rogers at least. I'd assume AT&T would be the same. You can test this by dialing *#*#4636#*#*, selecting phone info, and selecting LTE only. You'll see that there is no service. I tested this in an area I knew had great LTE coverage, and that led me to the conclusion that it's LTE causing the signal drops.
So how to fix? Simple, just change your APN to the LTE APN for your carried. To do that go to Settings -> More -> Mobile Networks -> Access Point Names. If you're experiencing this issue on Rogers, change the APN field to ltemobile.apn. If you're on another carrier, you'll have to search for their LTE APN configuration.
After doing this your phone should start connecting to LTE again, and you won't get those annoying signal drops.

So yeah the next update will probably fix the issue. It's not so bad in the meantime, Lightflow sill notify you that your nexus has lost signal, and you still get the internet and incoming calls.
We're not alone. Supposedly Google is "aware" of the issue.
i've hcanged my setting from '4g' to '3g' to see if i notice a difference (hopefully will) then when 4g is released or i get a 4g sim, can move it back up
Yes, I'm having issues too. The real problem is the fact that I have a Wilson cell booster in my home (supposed to have up to 5000 square foot range) and my n4 had full bars most everywhere inside. With my n5 It shows 1 to 2 bars if I'm lucky and quite often drops to none! The only way to get full bars Is to stand right under the indoor antenna. Not impressed, and I sure hope this is fixable!

I hate to revive a dead thread, but I was wondering if people were still having problems. Once or twice during the day that I can see I will lose signal for a few seconds only to have it reconnect. Running 4.4.2 so the latest update did nothing to help the problem as far as I can see and I have messed with my APN settings. On AT&T. The Google thread seems to have a lot of different problems on the same thread, and it is a bit unclear if people are still having this problem. This is very annoying for such an otherwise spectacular phone. Thanks and sorry again for reviving the thread... :fingers-crossed:

Appreciate the speedy reply. Hope Google gets on this fast. I also have LTE connection issues which has plagued both this and my original device so I am pretty sure its a radio issue. The phone loves to stay on HSPA+ even when there is a decent LTE connection: it's last in the pack to connect to LTE and first to disconnect when compared to others on AT&T.

My N4 with a combo radio sticks to LTE a tad better than my N5 with stock radio. Sadly, morrislee hasn't fiddled and combo'd N5 radios, and I'm not sure they've been tested and sussed out like the N4 radios. Citing the fact some with issues have flashed all the radios so far with minimal success means we wait for Qualcomm, after Google kicks them in the you know where.

[Q] Stuck on EDGE or GPRS

When I'm on data, my phone is stuck on EDGE or GPRS when it should go up to 3G or H+. I've tried restarting my phone, turning wifi on and off, turning data on and off and made sure my settings looked okay. Any help is appreciated!
Cataclysm 11/26, Franco r14, dalvik patch. And if it's relevant, I'm on Rogers wireless.
I'm not sure but doesn't Rogers use global frequency in which case you need the 821 model?
I've definitely had 3G and H+ on my N5 (abbreviations much?), but it just seems very inconsistent. It'll go from H+ to 3G, back to H+, then cut out completely, then sit on E or G for a while. Just trying to pinpoint the issue because it's getting annoying haha. Perhaps it's the frequency that's screwing it up but that's definitely not my area of expertise. I do have the D820 model if that's helpful.
I'm having exactly the same problem with Fido right now, I tried pretty much everything including
- flashing back the factory image
- tried every modems from the xda thread in the Nexus 5 Android Development section (currently my phone is on the D821 modem but it didn't change anything)
- changing my apn (but it was obvious that this was not the problem since the phone had a edge connection.
I'm really about to call Fido...
Still, I'm kinda glad to see that i'm not alone.
maybe that the data service in your personal area?
Well going back and forth between 3G and H is normal. It picks up H/H+ when receiving/transmitting and goes to 3G when idle to save power.

I called Fido, the technical support told me that they had something that was blocking me from 3G (but he didn't tell me what it was, he just told me that something was blocking me...) I had my beloved H+ back for maybe a whole minute and then it just switched back to Edge network.
All I wanted to know was if many customers have reported the problem or if I were alone...
Maybe if I'm lucky my phone will get back its 3G soon just like you.
I'm still having the issue today.
I called back Fido and they tried different things like desactiving/activing back my line, "updating my line" and more without any success.
Then I called google and told them the problem. They will change my Nexus 5 for a brand new but at the same time I feel like it is a software issue and not an hardward one... Well, we'll see, I never had a problem like that with any other phone before and the Nexus 5 never had any problem with 3G before yesterday.
I haven't tried everything yet, maybe you could try :
If you are in a LTE area, can the Nexus 5 connect itself to this network? Nearest LTE area from where I live is like 40 minutes away, bit too far just for a test.
Try with a sim card from another company like Telus or Bell, is the phone connecting to the 3G network? (I though about this while calling Google..)
Well, hope that the next phone will be ok.
Here are the few pictures just to show you a proof that even when I request a webpage, the phone will stays on 2g only.

Thanks for the update mark1s. Definitely let me know if a new phone fixes anything, although I'm also thinking it's a software problem.
The problem could just be that there happens to be patches of low coverage in the areas we're testing this out, which seems unlikely in big cities. But testing at work seems to have this problem, but testing this at home I pick up 3G and H+ just fine. Odd..

Shield LTE on T-Mobile issue.

Just got my Shield LTE today. This is my first tablet ever as well as my first unlocked device ever so I've never really had to mess with APN settings before. Long story short, I can connect and get HSPA+ ok but the speeds suck and no LTE at all. My Galaxy S5 can pick up LTE fine and get around 50Mbps down, but the Shield gets only about 5 down on HSPA+. When I search for network operators, my only choices are T-Mobile (2G/3G) and AT&T (2G/3G/4G). Any ideas as to why it can't find T-Mobile LTE network?
Does your phone work with LTE in the same spot? I got my tablet yesterday and moved the TMO SIM from by iPad to the Shield. Got LTE right away without doing anything with APNs. Depending on where you are, TMO LTE coverage is spotty.
Yes. My Galaxy S5 gets about 3 bars on LTE while sitting right next to my tablet that only has 2 bars on 3G. Just got off the phone with T-Mobile and they said they could see me connect to the LTE network and I did see LTE come up on the Shield for a moment but then it almost immediately dropped back HSPA+. I think its an issue with the tablet itself. I'm on hold with Nvidia now.
I'm still trying to get my Shield LTE activated on T-Mobile for the 200 MB free data for life deal. T-Mobile told me that their system saw the Shield's IMEI as a phone, not a tablet, and to bring it into a store so they can see that it is indeed a tablet.
The APN Settings came down by default for me and appeared correct with what I've searched online, but I'm having the same issue where I'm not getting LTE here in the PHX market, in all the places my phone gets full healthy LTE.
I don't want to complain about my H+ signal, but it's just not cutting the mustard if you will.
You find/hear anything useful here Hoju?
I'm seeing the same issue With LTE/Tmobile alsnly HSPA+
I've been in contact with Nvidia support since last week and they have had me send them numorous diagnostic files and bug reports. From what I can tell, the Shield is using NVIDIA
's Icera i500 modem which can be thoroughly tweaked through software updates. I'm hoping this issue can be resolved with such an update. Nvidia level 2 support told me that I was the first case of this reported, so I urge everyone suffering from this issue to contact support so they can see that the problem is not an isolated incident. I'm hoping to hear back from them today regarding this. I will update the thread when I do.
T-Mobile setup my imei number as an iPad to activate sim and didn't give me the pin, called T-Mobile and got it fixed, the pin turned out to be 1234, once he fixed the imei and changed pin, internet started working well and LTE is working as well. Also logged into T-Mobile.com/connectme I'm not sure if that's required but that's where you can buy more data. Hope that helps someone
Hi there, T-Mobile retail dealer here. I've tried 4 different T-Mobile sim cards (2 $50 simple choice plans, 2 $70 simple choice plans) along with 4 of their MVNO's sim cards (Univision Mobile, Straight Talk, Ultra Mobile, Lyca Mobile) and they all had LTE.
With all of the T-Mobile sim cards, the standard APN that's loaded in (fast.t-mobile.com) works perfectly for me.
For the MVNOs, using their respective APNs allowed for LTE, while using "fast.t-mobile.com" on those services only gave me HSPA+
I'm also located right outside of Philadelphia. Not really a populous area but we have good coverage with T-Mobile around here.
Hope this helped.
I also just added ro.ril.fast.dormancy.rule=0 to my build.prop, result so far is stable connection on h+. Without that it was flipping between 3g and h+ constantly and connection was unstable. ive been streaming music and it did change back to 3g, but not back and fourth like before, ill keep an eye on it.
maybe i spoke to soon, i still see it switching. Ill update after some more testing if this did anything or not for me.

Just out of curiosity have you noticed a difference in the last three days overall?

Not really, guess it was a placebo effect at first and just happened to stay on h+ for a while. from what i have read over the last few days is that on t-mobile's network it switches to 3g to save battery. I just removed the line i added, streaming music right now and just got a drop out. If someone knows or comes up with a way to force it on h+ I would happy, i could care less about battery savings if i just have this thing on my desk plugged in all day.
I got some time today, going to try staying off of wifi all day and see how it acts, might try a couple things if i can find some other options to test. if i find something ill let ya know.

Thanks for the response. I ended up exchanging mine with a new one that I just received last night. Right now I'm still testing and hopeful it will shape up, mine would drop from H+ to Edge, I do get LTE from time to time but it's very sparse. So far the replacement is doing well but i'm more and more convinced this is a radio issue as the tablet was really certified on AT&T. I've filed a ticket on my old one with Nvidia, no eta on a fix. Anyone that's seeing this go through nvidia support and file a ticket. Hopefully they can get it fixed in the next OTA.
I, too, only get H+ signal from TMO on my Shield. While it's normally fast, it sometimes drops and goes to E(DGE) or none at all.
EDIT: TMO could find nothing on their end via online chat. I'm going to test the SIM in another LTE device, and see if its a SIM issue. Waiting to hear back from NVIDIA. Really hoping our coming-soon 5.0 update fixes this!
EDIT 2: I just heard back from them that the TMO issue is an open bug "and will be fixed in a future update".
shield vs lte?
Yours at least connects, mine wont even do that I probably go to local branch again tomorrow if things wont change by the morning. I hope it works, but i cant activate the sim. Shield recognizes the card, under connections it says T-mobile but every time i turn off WiFi and try to activate the sim via cellular data, it keep telling me theres no connection yet i have 2 bars of their signal
So this means that I could but the 30 dollar a month plan? 5GB data, 100 minutes and unlimited texts?
Did anyone that was having a problem with LTE ever get it resolved? I just picked up the LTE version of the Shield tablet and have yet to see LTE and my phone is getting it fine. I hope a solution was found.

Yep, I'd be interested as well. I got that tablet since a few months and have problems with the radio too. I'm running LingeageOS 14.1. The latest few builds didn't even find the sim card anymore. Today I got back to stock rom for testing. Sim card is there, but it loses the radio connection every few seconds.

I just tried T-Mobile: works like a charm. It seems like Vodafone is causing the trouble. I've tried two different SIM cards and have the problem with both. Country: Germany.

What LTE band is your phone connecting to? I'm assuming you are T-Mobile? If you're in a band 12 area you might be out of luch as the North American version supports bands 2, 4, 5, 17, 7.

Dropped calls when going from lte to hspa/hspa+

Just recently I've noticed that I drop calls when I'm on a LTE signal. It is very annoying. Is anyone else having this problem. Does anybody have any idea what is going on here. I notice if I have a HSPA/HSPA+ signal I don't drop calls.
Actually I noticed if I turn LTE off I don't drop calls at all. I am on the AT&T network if that matters.

Same network, similar but different issue. Within the last couple of days my phone now hangs up the call after a few seconds. Sitting at my desk, signal strength is in the -70's, a call comes in and the LTE symbol drops to HSPA or HSPA+, (good so far) then no icon shows then the signal indicator goes completely blank, the call hangs up then after a brief pause the phone reconnects to LTE. I'm completely stock, running the latest CM 11S and I've tried everything I can think of to figure out the problem. I've wiped the phone, stopped using Google Voice, I have not added new apps lately, swapped out my SIM card into my OPPO Find 7A and it works flawlessly...I'm at a loss. At this point pre-ordering the N6 can't come soon enough for me.
That is actually what happens to me but I couldn't explain it as well. I'm on a cm11 rom.
I'm wondering if it has something to do with AT&T.
Have you updated to 38r?

Yup, updated as soon as it came out so it's been a few week now for me. Had the phone since early June, this has been my real first issue I can't overcome....pissed
Have you tried to turn off lte and just run it on 3g?

No and at this point I kind of don't care since I'm getting the N6 as soon as it launches. I can make due with my Find 7A for a few more weeks. In some regards it's actually better as a phone than my OPO. Probably going up on Swappa soon!
I was just wondering if yours is acting the same way with the lte deactivated.
Yep had this since i got the phone, sometimes on lte it just wont let me call and say " mobile network unavailable ", been on 3g for a long time and haven't had any problems.
probably because lte coverage where i live is meh.
Yeah but WTF, this is bull**** to have an LTE phone and force it on 3G. I'll put the SIM card back in and try on 3G for a bit but if I get frustrated and throw the thing out the window its on you : -)

So far so good when selecting 3G the phone holds the HSPA or HSPA+ signal.
Looks like on the 1 + forums there's a lot of people having the same problem. Someone said it's going to get fixed in the next ota. Looks like the last update 38r boogered something up.
I just want to say that for those who are not aware if your phone shows low LTE signal, that has absolutely nothing to do with voice services and the quality of voice services you might get. As soon as you type in a number and hit call the phone automatically hands off connection from LTE to HSPA or 3g to make the call. This is 100% normal. VoLTE is not available on our phone nor is it activated on Tmobile yet I dont think but likely soon.
I expect that once we get official Lollipop and tmobile works out their nexus wifi calling dealio they got going on then we will also be getting the same wifi calling and texting magic. No need to get freaked out people.

I was aware that there was no Volte. I know that it is normal to go to 3g but it never dropped a call doing that before. I must disable lte so the call doesn't drop. I know this only because I have an att microcell and it forces my phone to 3g for full 5 bar voice service.
Yea microcells do weird things, the hand offs are messed up in general in android I think with them. Sorry thought you were on tmobile. Still not use to being in a forum with an unlocked phone

Birdsfan or others,
By chance did you have wifi off? I just been doing some testing and noticed this:
wifi on/lte on = no dropped calls
wifi off/lte on = dropped calls
wifi off/lte off(3g only) = no dropped calls
If you want lte activated and make phone calls without it dropping calls then turn on wifi?
Check it out, see if it works.
I found the exact same results as tdamocles
Left the house and learned that there needs to be wifi in connected state for calls not to drop.
I just started having the same issue, exactly as described.
WiFi + LTE, no prob.
H/H+, no prob.
LTE without WiFi, phone switches to H/H+ and connects for about 2 seconds then hangs up while the signal icon goes blank, then back to LTE.
I tried reflashing stock 11S with a clean wipe, 38R.
I tried the latest nightly with a clean wipe.
Really at a loss here.
I really like the phone and CM but I need my phone to work as a phone....I'm done I'm pre-ordering the Nexus 6 Wednesday.
I dunno, I just tried reverting, via clean install, to 33r and the issue persists (did NOT go away).
Makes me worried it's a hardware thing.
