Sprint 4G/LTE but still calling issue, - G2 Q&A, Help & Troubleshooting

In my area now we have Sprint LTE. very happy finally.
I am guessing LTE is for the DATA. But can't that be used for calls. Still have calling issue. Hardly any bars. I have so many drop calls and very poor reception. Vendors (Phone makers and service providers) are making phone big, slick, faster and more and more features but forgetting that it is stll a Phone and main function should be making phone calls. Pretty soon I will be able to microwave my food with it but wouldn't be able to make a decent call. Is there a hope to get good connection?

Yes, as of now LTE is for data. If you're having dropped calls and reception issues, then have C.S look into it more technically.

Thanks, I did. They went thru few routines. Update PRL, PROFILE and then they are sending something. I am not sure what? After all that they will notify engineers and someone will call me. Other thing I hear; may be we are still working on towers and updating and tweaking. That was more then 10 days ago. May be I will call again.

So I hear Sprint is going to start VOIP (WIFI phone calls) for two phones.Why not LG G2? OR Why not VoLTE?

Just happened to come by this thread, I have tmo. Not sprint
+ /Note 3 \/ nexus 5\/ nexus 7 LTE-and on ALL, no matter were I travel, as soon as LTE kicks in my signal drops to no bars and my calls drop, it seems to ping pong/ best response from tmo. Is Im between towers of cell and LTE towers, While there upgrading....
So that brings me to think that while Every cell phone company is upgrading there towers to FULL LTE,
"Well be stuck in PINg PonG LiMb0"

Signal Problems: is it Sprint or the EVO?

I switched over from Verizon and I have had my EVO since the 4th of June. I like the phone, however I get very poor reception. At my house inside, I get 1 bar, sometimes it will be no bars or 2 bars. I used to get excellent reception in my house with Verizon (usually full bars). My wife is on T-Mobile and even she gets 3-4 bars (out of 5 bars) and never has dropped calls. I always get dropped calls.
I used to be able to ride in the elevator in my office and talk on the phone. Quality would drop and i would lose bars (down to 1 or 2) but I would almost never actually drop a call (this is on Verizon). Today, in two elevator rides on the phone, they both dropped.
Now my question is.... is this Sprint or is it the phone?
If it's the phone are there certain ROMs I should try that improve the reception?
Thanks!
You should try to do the little hack to get on verizon towers without being classified as roaming. Check it out, if its sprint then you will see once you try it.

Different radios might work. For the last 4 years I've been an AT&T customer. I understand that CDMA apparently isn't as good at signal building penetration compared to GSM, so that might be a limitation.
However, both Verizon and Sprint utilize CDMA, so I find it odd that someone with Verizon could have a better signal than Sprint, since I'm also told that (assuming your phone has the "roaming towers" option or whatever it's called enabled, and it is by default, at least on my phone) they use the same towers, so why on earth would there be a disparity?
I'm guessing it's the EVO, or something to do with its casing, because some places I get excellent reception indoors, and others, like Sam's Club, is a complete dead zone except for the front third of the store closest to the exit.
That being said, my wifi reception (or at least indicator) totally blows. I hope a firmware update address that and the 30 fps cap, as well as reception (if it's the phone).
Try the *techknowfile's* - Hack the HTC EVO - 3G w/o Sprint EVDO coverage!
It worked for me. From having no bars went to full at home because of Sprint coverage. And the EVO does not have the option of roaming, just the automatic roaming and never worked for me.
About Verizon and Sprint they are both CDMA but they have their own towers. Is not the phone. And at Walmart almost every phone loose signal. I have friends w all carriers and they all get poor signal.

Obtain your MSL (aka Master Subsidy Lock / Password. SIX DIGIT NUMBER)
Dial ##775#, a password prompt should appear. Enter your MSL into this box->hit OK->tap on the "Update PRL" button. Make sure "All Folders" and "Type: prl files" are selected. You should see the downloaded PRL (00001.prl) on the list; Select the PRL->Press Menu->Commit.
Search the forum for Hack the HTC EVO - 3G w/o Sprint EVDO coverage! under "EVO 4G Android Development"
the tutorial is on the first post by Techknowfile.
try a different radio, or maybe its just the area u are in? on ATT, my friend has an iphone, and i had the fuze, and he always got signals where i didnt, so it could be the phone...
You can't go by bars on CDMA... You can have ZERO bars and still be able to make crystal clear calls and send and receive data on CDMA whereas on GSM you hit 3 bars and your calls start cutting out.
Anyway, I've noticed that the EVO is really crappy with data speeds - but voice quality it is bar none the highest quality cell phone I have ever used.
Well, if the Evo simply has poor reception the Verizon hack shouldn't make a difference.
I like you have poor service in my home, always have. I got an Airave to solve that problem, it works well so long as I also am connected to Wifi otherwise it tends to hop between 1 bar of 3G and full bars of 1xRTT.
I tried the Verizon PRL hack. The signal was a little stronger, inline with what my roommates on Verizon got, but it wouldn't connect to the Airave at all. Did seem to have a hard time maintaining a 3G connection. I wasn't losing the signal, it just seemed to drop the data connection, but I still had a voice connection. Because of that and the airave issue I switched back.
The funny thing is, the EVO has better signal reception than my TP2... it just has crappy data speeds.
really? i get amazing data speeds on 3g, also i found out today that wifi speeds and signals are being fixed via software update from HTC, just got an e-mail from there. something like 700 down and 700 or so up.

If it helps, everybody in NYC knows that Verizon is the best in signal. You can get signal with them where ATT and Sprint can't. ATT has the worst signal in the city of the 3 of them. So it might be the carrier. I don't know if this is true somewhere else.

I have a simular issue, so I called sprint today and the tech found that the tower nearest me (about 1 mile away) was "out" so that was my problem so he generated a ticket to fix the tower. The funny thing is that he indicated that in general thier system can not tell them when a tower is out, customers generally call and indicate a service issue then they can remotely check the towers in question for issues . Man that is not the best way to check towers . Oh well the tower I need should be fixed in about 24 hours based on the tech I talked to.......he also said good thing I called Man they have a nutty system
Verizon's method of checking towers isn't much better if all they have is one guy walking around asking "can you hear me now?"

i've found it to be the opposite in my city. verizon is terrible and sprint is awesome. maybe in your area, sprint just isn't as good as verizon? don't think it's the evo.
This is easy to check.
Go to a different area and see if the signal gets better.
My own evo is better than my old TP2, much better reception (I don't roam at work, on the basement floor, whereas TP2 used to constantly) and 2-2.2 down / 0.6 up Mbps.

I just switched from a TP2 to the Evo and I found things to be quite the opposite. Constantly 1 - 2 bars less of service with the evo dropping to 'no service' where the TP2 at least had 1 or 2 bars. After many years with HTC products, Fuze, Tilt2 on ATT and the TP2 and EVO with Sprint I have found that its really hit or miss with their products. Some phones of even the same make and model are just better then others. The first Fuze I got had horrible horrible service. Went to the ATT store and they agreed, warranty replacement phone worked beautiful. Now with that said the EVO does seem to have consistently faster data speeds then the TP2 did. Between 600 - 900 with the TP2 and up wards of 1480 on a test I did yesterday with the evo. Still no where near the 2000 - 2500 the ATT network provided but they ticked me off with their two week tower outage in this area... what good is speed if the phone doesn't work?

Reception

I have horrible reception in the house i live in. I was wondering if theres any tricks that i can use to get better reception inside the house. I have to step out just to make phone calls half the time so any help would be appreciated. Thanks
Do you actually have no signal, or are you going by the bars. I don't have great reception at home either, but make calls all the time here with the phone showing no bars. I leave my phone in 2G only mode as 3G at my house is spotty at best. That way the phone isn't trying to switch between 2G and 3G. I find this phone has better reception than my previous Sony TM506 and Nokia E73 at my house.
There are rumors that T-mobile will launch a WiFi calling app for android. Who knows when, but I've heard it mentioned by t-mobile sales reps. (specifically with regards to the vibrant)

That would be a thing of beauty not that my reception is terrible
I should also mention that I'm talking corporate sales reps not retail sales reps.
Tha would be awesome. I have good reception, but in my brother's house I get no service, but I remember when I had the Blackberry, I could use the wifi signal and had perfect reception in his house

In my house i have no service in the house, i have to go outside to make calls. If only they come out with the app to make phone calls over wifi, that would make this phone all the more better.

[Q] Is it possible to use data on the phone while on a voice call?

Long time AT&T customer probably switching to Sprint, been eyeing the Epic..
If I get a voice call, is it possible (if I'm using a BT headset or speakerphone) to fire up a web browser on it and use that while I'm in-call? To look things up, or whatever?
If it can't do that, are there any other Sprint phones that can (EVO, for example?)
Thanks!
if i remember right, you can use data and voice only when you are connected onto 4G and WIFI, but not 3G. i have not tested this out yet to confirm but i remember reading that somewhere if i read it right. i also came from att (iphone) and being able to use data (3G) and voice at the same time was a major plus. ill have to try it out though later on my epic.
Yes u can use data while on a call only if you are on WiFi or 4g. Tested and verified.

Some might say it is a "limitation", however is it the reason why cdma networks do not suffer from dropped calls like gsm networks do.
For more information, you can check out this rather lengthy post about why cdma is better than gsm.
yeah, i experience the same thing. it's becoming pretty much a deal breaker for me, as often i am on the phone for an hour or more and am trying to look things up at the same time. no joy. plus the abysmal battery life has me glad that i am still in the 30 day window ?; i like the phone a lot otherwise. wish i could get it for ATT. i have never had problems with their service, and would love to be able to talk and surf at the same time.
On 3g only voice.

Most likely VoLTE...
Longer battery?!
It's VoLTE. Or, simultaneous Voice and Data as was missing from the device at launch with the promise to be fixed with an update by the end of the year.
I'm curious, though, if it counts towards your data allowance to use VoLTE. Does anyone know?
It doesn't count against your data plan according to the Verizon FAQ

Voice no, video yes.
It's disappointing that the update is (apparently) only/mainly VoLTE, and not Android 5.0. Since carrier certification is a relatively slow, painful process, I think this is a sign that the Lollipop update is more than a couple months away.
I was initially excited about VoLTE, but I wasn't impressed with it when I used it briefly on my Droid Maxx. First, it wasn't reliable- I had dropped calls, and calls that never even rang my phone. Second, it killed my battery. It was rough- really rough- on it. I think both are related to the relatively weak LTE signal I have at home. To deal with the signal problems I have a Verizon network extender, but it looked like my phone was preferring the weak LTE signal over the strong signal from the network extender.
I wish Verizon would have just sucked it up and supported Wifi calling with Advanced Calling 1.0. I don't understand why they dislike Wifi calling so much. They're going to eventually support it, but the company's statements suggest they aren't happy about it. Who knows how much support there will be for it, though. Verizon apparently plans to release a LTE network extender at some point, which is only useful in certain niche situations if Wifi calling is broadly supported on VZW devices.

Wifi calling is for carriers that need someone else's network to supplement their own shortcomings.
That is why they don't implement it.

So is it just a messaging problem? Verizon doesn't want to support wifi calling because it's an implicit admission that they don't have great coverage everywhere?
Generally, I agree VZW coverage is pretty good. But, it's not great at my house, and its terrible at my workplace. VZW already implicitly acknowledges that they don't have great coverage everywhere by selling network extenders. They're continuing that by coming out with LTE network extenders (someday).
It just seems like its a cheaper, better option to support wifi calling, rather than forcing people (with coverage problems) to shell out $200-300 for a network extender.

I still think every carrier should support this. I'm in IT, and constantly find myself in data centers, or even meeting rooms deep into a building that you couldn't even make an E-911 call from... It really wouldn't be that difficult. When TMob had UMA back in '08 and I had a BB, I used it extensively. It was never because TMobile didn't have enough coverage.. Carriers basically make money when you use their network. Yes, most people have unlimited plans these days, but they build their network around the use it has. So why wouldn't they want you to be using your phone, minutes, texts, etc? On the other hand, why wouldn't they want to offload congestion to networks they don't have to maintain or pay for? There just aren't any down sides to have WiFi calling/text/mms.

HTC U11 AT&T support and collection

this is going to be an AT&T specific collection thread for this carrier specific stuff like VVM and try to make wifi calling work, also users can ask any questions related to AT&T and I will try to answer them and hopefully other users can help to.
HTC lying about AT&T "compatibility"
U11 does not support VoLTE on AT&T
U11 does not support WiFi-Calling on AT&T
U11 does not support Video Call on AT&T
U11 does not support Integrated Visual Voicemail on messages app like it use to on HTC One M7, M8 & M9, you need the stand alone app which is crap...
the phone works for calls data LTE works MMS haven't test yet I don't use them....

Argh... This sucks. I'm in an area where coverage quality has dropped significantly, and I spend a lot of time in a building where almost no signal gets through from any provider. Wifi calling and texting has become a lot more important for me for that reason. I can get by without the extra features, but it's tough now what I've had them (currently using an S7 edge and Note 5).I guess that leaves me with no option but Samsung or LG (and all of the provider bloatware).

Don't activate the U11 on AT&T, once their computer "knows" you have an uncertified device you lose LTE data and are forced onto HSPA+!
Does anyone know an APN setting that will reactivate LTE?

Not a fair critisim for HTC. Even if the phone is capable like my non-AT&T S8, if the phone does not have the AT&T logo on it they will not allow these features. So complain about AT&T like I do.

See if you still have LTE during a call. The LTE icon should go away and if you go into about phone and then network, it'll most likely say HSPA. The problem is we're not getting services like VoLTE and wifi calling. In normal cases, HSPA speeds should be manageable considering the average phone call won't be very long and there's wifi nearly everywhere now. This is just bad for those in areas with poor reception. I've been doing ok with the whole issue since I never really noticed much of a difference with HD voice and I'm usually always somewhere with wifi.
My question is what did they do differently with the U11 than the 10. We never had any of these issues with the 10 being unlocked and not certified and all that bs

The importance for me & probably for many others on getting VoLTE is that I do technical support on my phone and trouble shooting while on a call takes to much time most of the time, that being said if I don't have the option to make phone calls on VoLTE means internet speeds while on a call is crap.... I really don't care about HD call clarity as far as I can here the other person, but the internet speed while on a call it is important to me the faster I can browse the faster I can provide technical support

Having a weird issue with my U11 on AT&T. I randomly lose all signal for no reason then takes a good 30 seconds for it to connect again.
It has happened at least a couple times a week mid phone call which is really obnoxious. I have seen it happen a few times when I am just browsing through my phone not on a call so I know its not just a calling issue, and I am sure it has happened multiple times when I am not looking at my phone at all and I don't notice.
Anyone else had this issue? An issue with AT&T and can be fixed by a firmware update? Or am I alone and need to RMA?
I know this thread is old, but can't we use the ATT RUU if you do what you need to do? We used to be able to go back and forth, at least that's what I did with both my M7 and M8. If you really need those features, that's what I would do.
