Evo on Alltel NO 1X ?? 3G Works

I have used the latest licensed copy of CDMA workshop to change the SPC to 000000 on this Evo and set the NAM1 and EVDO settings EXACTLY identical to an Alltel flashed and branded HTC Hero, of course the usernames have been changed to my cell number... Has exact same PRL, everything.
I have rooted and it's running stock latest 2.2 sense rom.
It's up and working correctly on alltel's network, 5 Bars of 3G service but it says I am roaming, the Alltel branded Hero I have here is NOT roaming and is activated on a different cell number on the same alltel account in the family plan.
I re-read and re-wrote all the values in cdma workshop and re-compared everything to the hero, it's still roaming, tried *228'ing and updating PRL, updates correctly but... alltel pushes the same exact PRL 31005 that I originally programmed to it. This is the same PRL running on the stock alltel hero, evo still says it is roaming.
When I force the phone to CDMA only, I get nothing but "data call failure" messages and 1X will not work, 1X logo doesn't even show up on the status bar, when I have it in automatic mode (1x/3G) and I leave a 3G zone, where I know 1X works, the EVO will not connect to 1x, just keeps throwing "data call failure" messages at me. When it's connected to 3G it doesn't give me a problem at all, 3G works flawlessly in all apps until I try using wifi tether I get data call failure again, pdanet works perfectly with 3G though when tethered. 3G does not drop either, works perfectly. In ##DEBUG EVDO it shows Authenticated, I'd like 1X to work because not everywhere I go has 3G coverage and these data call failure errors are every 10 seconds when im not in a 3G zone.
What's the deal here? My last htc android phone (eris) that I flashed to alltel worked perfect, 1x and 3g switched when needed without issues. I have gotten rid of ALL sprint apk's in the system/app. Is there any other apps that are forcing the phone to try to 1x connect to sprint's network? Profile 0 and profile 1 on my programming are all set to alltel's data values.
Thanks for any help.

Ok Steve I guess I will illustrate this time what I have done so maybe this can help. I don't know what your area is like in regards to VZW or Sprint coverage, but I have found that the Evo does not like the Alltel PRL. I understand you used the identical prl when doing the Eris with no issues and I did the same with the HTC DInc but it's not the same game this time. The phone will say it is roaming even if you have your home SID set properly for your "correct" Alltel PRL. So here goes:

Disable phone radio on Inc2?

I was recently given a phone that can't be activated on the VZW network because of a broken contract. is there a way to disable the phone radio without it affecting the Wi-Fi? I wanna give it to my son to play the learning games off the android market without worrying about him calling 911 or something like that. Is that possible ?

If the phone can't be activated on the network, how would your son call 911 or any other number?

Even though the phone can't be activated it still has a signal and it's still capable of making calls using a credit card, emergency calls and calls to VZW operators. I know he will eventually figure out airplane mode so I'm looking for a more permanent solution.

The only thing I could think of would be to go into network settings and change it to something like evdo only, that way it can't connect to standard cell signal.

Or you could set it to gsm mode so that there won't be any signal or anything

Thanks I'll try that.. maybe that and airplane mode will be work as double protection

I use my Eris for music and white noise for sleeping baby with airplane mode on, then turn on wifi. No cell signal, but email and everything else works fine.

Try dialing *#*#4636#*#*. WHen you dial that it will open advanced settings. Click Phone Info. In the Phone Info screen you can turn the radio off.

Disabling VoLTE (Verizon)

Hello all!
Is there a way to turn off VoLTE? I use my phone as a hotspot, so when I get a call, I don't have internet access. I'm assuming this is because of VoLTE since my last phone (Droid 4) didn't have this issue.
Thanks!

Is this the option you are looking for? 'Enhanced 4G LTE Mode'

I always thought having that option disabled is what caused data to turn off during phone calls. I have it enabled and I can still use data while on the phone. That's the toggle to the off VoLTE though.

Sounds like you aren't using VoLTE in the first place. Turning it off won't give you data during a call it would do the opposite.

I've tested it with that both on and off and still lose LTE during a call. :/

Talk and web is only available if you have advanced calling option turned on within your verizon account. Its free.

It doesn't sound like you're using VoLTE exactly because you stated you can't use simultaneous voice and data. Here's the deal: To save battery power or whatever, the additional radio added to Verizon and Sprint (CDMA) phones to enable 4G has been removed from a lot of them, rather converged.
Verizon has always had this problem and they got around it by, finally, adding an additional radio to handle the 4G to many phones. On CDMA networks it's either (I think analog) voice or (I think digital) data. Then, I guess expecting this great big transition to VoLTE (and only needing one radio to simultaneously handle LTE and Voice over LTE) "they" reverted phones to the original model. I mean that has to be it... I would gladly charge my phone more to be able to be able to hotspot and talk! Or maybe they want to sell more JetPacks and separate line access fees!
(This is what allows for all that red on their coverage maps as Verizon's original voice frequencies do rock for signal strength and reliability. The data maps look a lot more similar amongst the carrriers: concentrated on major "markets" as the efficiencies of cities drive the capital to create the networks--rural areas have lousy 4G coverage).
The GSM networks from T-mobile and AT&T automatically fall back to 2, 2.5, 3 and 4G frequencies and can use the newer and the older networks at the same time. You also get better conference calling (up to 5 people) and call management on the GSM based networks.
If you want to use voice and data at the same time on Verizon, edit your account preferences to enable Advanced Calling 1.0 for your line. It is free. Also enable Enhanced 4G LTE mode as shown in the screenshot.
But VoLTE seems to bring its own issues: call complete rates will drop, call quality will drop, static bursts occur at the beginning of calls... it's a real mess.
I really miss T-Mobile, but their network isn't as good and I save money being on the family plan with others on Verizon.

Hi guys, I am having the opposite issue.
I can't get VoLTE ("HD Voice") to work. As a result, no internet when I'm on a phone call. A real pain in the butt.
I'm on CM13 on my Nexus 5x and using Verizon.
I had previously activated this feature on the Verizon website, and it shows the VoLTE flag is 'on' in the phone info/service settings menu. I've seen posts elsewhere where people say CM13 is not working properly with VoLTE.
Should I flash to a different ROM perhaps? Appreciate any ideas...

Hack WiFi Calling into working with unsupported Carriers

Hi,
As my Provider does support WiFi Calling for the Samsung S6, S7 and iPhones i tought it should somehow be possible to get it working on my HTC10.
With the newest 1.98.709.5 Update the ROM itself should fully support VoLTE and WiFi-Calling, but it's a TW branded ROM so it obviously only supports Taiwan Carriers.
So there are two options:
A: Fake/Spoof my phone into thinking it's connected to a Taiwan Carrier.
B: Modify the System/App that it works with my Carrier.
While searching the Web i mostly found DAU webpages that show the setting option to activate WiFi calling ~.~
Only for the Z2 there seems to be a modification to get VoLTE and WiFi calling working. But they have way more stuff to edit and my carrier does not support VoLTE anyway.
So after stooping around the system for a while i couldn't find anything in build.prop related to WiFi calling.
But i found these few APKs in /system/priv-app that might be related.
CustomizationSettingsProvider.apk
SettingsProvider.apk
WFCWifiCall.apk
I tried to decompile them with APKtool and take a closer look.
The thing is... i suck at stuff like that. I have literally no idea about android app development.
.smali ? wtf is that?
In the /res/xml/ of WFCWifiCall.apk i found an ims_qanda.xml and ims_qanda_metropcs.xml
The MetroPCS simply has MetroPCS instead of T-Mobile

<Question>What is Wi-Fi Calling?</Question>
<Answer>Wi-Fi Calling lets you make and receive voice calls and text/multimedia messages over Wi-Fi when your phone is connected to a Wi-Fi network and registered with the T-Mobile network for Wi-Fi Calling.</Answer>
<Question>How do I enable Wi-Fi?</Question>
<Answer>To enable Wi-Fi, use the wireless control section of your Android settings menu.</Answer>
<Question>How do I enable Wi-Fi Calling?</Question>
<Answer>By default, your phone is enabled for Wi-Fi Calling as soon as you enable the Wi-Fi radio. Wi-Fi Calling can be controlled from the Wi-Fi Calling Settings.</Answer>
<Question>How do I know when I am using Wi-Fi for my calls?</Question>
<Answer>When your phone associates with a Wi-Fi network, it will automatically try to register with the T-Mobile network for Wi-Fi Calling. Once the registration has successfully completed you will see the Wi-Fi Calling icon in the Status Bar. You will also see the Wi-Fi Calling icon displayed in the dialer (in place of your regular calling icon) and you will briefly see a message at the top of the screen saying, "Calls will be made over Wi-Fi."</Answer>
<Question>Will calls or SMS/MMS over Wi-Fi be charged differently than my cellular calls?</Question>
<Answer>The primary benefit of Wi-Fi Calling is to increase your coverage in locations with Wi-Fi. Calls and messages made over Wi-Fi will be charged like cellular calls for certain plans.</Answer>
<Question>What happens if I lose Wi-Fi coverage?</Question>
<Answer>When the handset loses Wi-Fi coverage, any active calls will drop and the phone will connect to the cellular network if possible. You will receive a prompt if your call drops due to a loss of Wi-Fi coverage.</Answer>
</IMSQandA>
But i'm not even sure if that's the right file to look at.... TW phone and it goes on about American Proviers? mhkay...
So in short, i have no damn idea.
I'll take any hint, thanks.

Don't forget:
WFCService.apk
wfc-provider.apk
best of luck

The WFCservice seems to work fine...

I can launch that via activity launcher, but NOT enable it with the button
The WFCprovider does not seem to block it either....
There seem to be quite a few IMS error codes.... Maybe they'll help.

Is the wifi calling feature working with this???

Moto G7 Power - No VoLTE or VoWiFi - Any help or suggestion

Hello experts,
I wanted to see if anyone else has any experience in this?
I raised this issue on LineageOS GitLab, but while they come back to me, is anyone else experiencing this?
Expected Behavior
T-Mobile Network
VoLTE: If I make or receive a call, while VoLTE is turned on, the Cellular connection should remain on LTE.
VoWiFi: In low or no Cellular signal conditions, while VoWiFi is turned on, the calls should travel over WiFi.
Note: All the settings are enabled in the phone. In settings, and confirmed under ##4636## (see screenshots).
Current Behavior
T-Mobile Network
VoLTE: Turned off WiFi for debugging. Made an outbound call. During the call, the connection changes form LTE to 3G. Call is not doing VoLTE. Also true for inbound call.
VoWiFi: Moved to a location with no Cellular Signal, but was unable to complete any calls over WiFi.
Note: See the screenshots, I have all the correct settings enabled, but still IMS doesn't register.
Possible Solution
All toggles work, so the actual service should also work.
Steps to Reproduce
NOTE: First I tested this on complete STOCK ROM, fully updated, on T-Mobile network. Both VoLTE (on by default) and VoWiFi work. Next after installing LineageOS, I tried on the phone:
Went to Settings > Network & Internet > Mobile network. Turned on both the options, rebooted the phone.
After reboot, went into ##4636##, but that still shows IMS not registered.
Turned the WiFi off for debugging. On any outbound or inbound phone call, the cellular connection changes from LTE to 3G. Went to a place with no Cell Signal, and cannot get any calls over WiFi.

Any updates on this? I'm thinking of buying one of these, but no VoLTE is a deal breaker.

Same device, same carrier, exactly the same problem on LOS 17.1 and after upgrade to 18.1.
There are reports on GiLab, but no news/updates on that...

Other device (oneplus 5), but exactly the same problem on LOS 19.1 with fresh install (3 months ago).
Very few search results on duckduckgo and google, most results show solution with steps that you wrote in discription. Seems like on ly few devices with this problem.
