Voice isn't transmitted over LTE so it's more than likely your phone, or you have the wrong network mode selected. If you don't want to be on LTE you need to be on CDMA/EvDo Auto....

Yea, voice goes over 1x. And probly always will, there's just not enough data in voice to warrant anything more.

I am only getting LTE/CDMA or CDMA only, no other choice. I guess I will just keep it rocking LTE and just connect WiFi when I can.

There is an app called lte on/off for free in the market.

Oh, I just set it with dialer codes and I am sure it just a accesses the same menu.

I just spent a week in a 'no LTE' area. I turned off LTE in settings (CDMA only) and had no problems with phone calls.

What does LTE turned off have to do with being able to make a call.
You can take the SIM card out and still make a call.

Not sure but with my phone if LTE is off all my calls close before they start with a message of "Call lost".

That is not right, if your phone is doing that it is broken, take it back and get a new one.

Actually if you take the simcard out you won't be able to use LTE phone at all unless you want to browse the internet over wifi.

Nobody said data without SIM, just voice, which is accurate. You can still make calls without the sim inserted.

If you have assisted dialing turned off, it will cause issues with trying to dial numbers.
If your numbers have area codes and a "1" in your contacts, they will not work unless you have assisted dialing checked on.

Totally not true. I have yet to have any problems, and I have an out of state number.

This seems to work better for 3G!

I find this below to work better than the *#*#4636#*#*. Seems like 3G is stable now. I have yet to see the 1x since I did this. It does turn 4G completely off though. From what HTC support says they are working on a fix for the radio, camcorder, txt, and battery issues. I was told an update when it comes should set it back to LTE. We don't have 4G yet so a good 3G signal that sticks instead of dropping out to 1x is fine by me til they get it fixed.

Are you on WiFi, because ehrp whatever is what allows you to talk and surf, putting it on rev a is just putting the phone on the old non talk and diem network.
Wifi off and it still works. Must be that it just turns the 4G off. I get email, txt, can put the wife on speaker and look at forums on the web and browse sites no problem.

I thought it was known that you can use 3G and talk on this phone at the same time. You don't need 4G. I used it once just to see that I could. I'll probably never use it again.
ehrpd is not the talk and surf thing. It makes the handoff between 3g and LTE work properly. Without ehrpd all your data connections will reset when you go between evdo and lte
All this like does is show you how to set your tb so it will stay on 3G and not 1x, which it kills the 4G. I see no point in having 4G search if I'm not in a 4G area. Plus it helps that battery issue a bit too.

Best way to avoid Intl roaming?

I am about to travel overseas. I'm not going for long enough to warrant getting a PASYG sim but will have near constant access to wifi. I'm with t-mo USA and have wifi calling set up and use Google voice for texting and vm. What's the easiest way to turn voice and mobile data off but keep wifi on? Best solution I could think of was to take the sim out, are there other better options?
Idk about your phone since im an evo owner but you should be able to turn on airplane mode on your phone and have wifi on at the same time. I do it quite often on my evo actually. So you will have all your carriers radios off so no charges, and still use voice for calls and texts.
Try doing it really quick and report back if u can or can't so I can try to help with another solution

Edit: ok so this is not perfect. Wifi calling is disabled when in airplane mode, which IMO is stupid. I guess they are trying to get some roaming fees if you leave the Intl wifi signal.
Going to try wifi calling with the sim out.
All but wifi. And no problem

If there is no t-mo sim card, wifi calling is also disabled. I tried with no sim and a UK PAYG sim both same result, no wifi calling.
Well that's two good options that should work but don't.
Ok I found a solution. Send me a pm and I will type you a guide and some screen shots in the afternoon tomorrow. I have to go to bed for work in the morning. So once I get off ill send you instructions on how to do it.

[Q] No calls when on 4G?

4G is flying, but I have noticed my calls automatically go to voicemail when the RAZR is on the 4G network. It doesn't even have to be in use, they just get rerouted to voicemail. A friend doesn't have that problem on 4G with his SGS3 so I'm thinking it's not the network?

Definitely your device, I have my 4G on whenever the phone is on and haven't had a single problem. Actually, I had my tethering on a couple days ago using 4G and was browsing the web on my phone at the same time and when I got a call from the lady friend, the data connection continued without a hitch. Sounds like you may need to consider a replacement, unless someone else has some info I am not aware of. Good luck.
Same here I get calls while using 4G

Yup no problems getting calls when on 4G here either....
Telstra firmware made calls go through when in 4G but then mobile network had to be manually re-engaged... I flashed the JB from SFR and now no incoming calls. Seems to be a baseband/fw issue?
Anyway did flag it with my provider maybe it's a possible bug. Who knows.

Hmm... does sound like a baseband issue. I would almost try hard reset? I have never heard of this before. I'll stay active in this thread though if nothing is resolved via your provider. Nice speedtest, by the way
Doesn't work. I am going back to ics tonight this jb sucks on my Phone
Also, wipe and reset didn't work. I'll retry tonight.

No data during calls?

Searched around on here but saw no results. Just noticed that during calls, data doesn't work. Is there a fix?

Data only is available during calls if you're on LTE and not doing VoLTE. Can you confirm what your connection is like?
I have LTE most everywhere but it does drop to 3G occasionally at my house so that could very well be the reason.

Yeah,,,the M8 is SVLTE, not SVDO (like the old Thunderbolt that could do voice/data on 3G) nor is it VOLTE.
You need to be in an area that your phone is receiving both a 4GLTE and 3G signals as it will use the 3G signal for voice and uses the LTE for data. Our phone never utilizes LTE for voice (I presume it uses 1X when there is no 3G signal available for voice...but that's rare as Verizon's existing 3G footprint is huge).

At your house, though, it should have data access over wifi. Unless, of course, you have wifi turned off.
I believe Wi-Fi was indeed off in this particular case. Thanks for all the help though!

Simple. U see 4g network in nav bar u can talk and surf internet. U don't, u can't UNLESS connected to WiFi. Easy.

Wifi calling

Is this available on Verizon? I enabled it in feature.xml and see the check box under phone settings now but how do you switch to wifi calling?

I don't think it's available on verizon.

I do believe that Verizon is using Advance Calling as a way to use WiFi for calls as long as your phone supports Advance calling. Of course it still has to be enabled and it still uses minutes if you don't have unlimited talk time.

It is when you're not on WiFi. If I remember correctly Verizon has the calls going over WiFi when connected even if you're in LTE coverage.

If that's correct, I should be able to make calls over WiFi if I have super spotty 3G coverage? I'm out in BFE Kansas and despite being on WiFi and having advanced calling enabled, I can barely get a call through. I was pretty sure Verizon doesn't use WiFi at all for calling.
Yeah I don't think volte uses wifi. I wish they'd add it so we could make calls when we're outside the us
