I've done several Google searches on this topic as well as focused searches on the CM and XDA forums; I figured it was time to just ask the question myself.
So I noticed that Wifi Calling started missing in in the CM7 nightlies sometime after #21. I ran across someone from the CM forums who saw theirs returned after his upgrade from #28->#30 (which I did not see on mine even after a full wipe).
Is there a setting or condition on my phone that prevents me from seeing/activating this feature?
Thanks in advance,
Reg
I've been running CM7 since build number 0 and now I'm on build 31, I have flash every nightly released and have always had wifi calling on every single build.

So I did a clean install of #21, which had wifi calling, but when I upgraded to 22, it was gone. Might anyone else know what I can do to install?
Thanks,
When you are upgrading, what are you wiping? You only need to wipe cache.

I've tried multiple things: cache wipes, no wipes, "clean" installs, manually formatting each mount point. None of that matters for me. Wifi calling only shows up in builds up-to-and-including 21; after that, it just vanishes.
Thanks for trying though, dude.
As i installed the CM 7.0.0-RC1 with Nightly version 2. and i found the same thing means WIFI is not working but when i press the power button and found the option REBOOT and select this option and then again i select the option REBOOT, Phone rebooted and then turn on wifi and it started working. so all you have to do is to Reboot the phone as i said. you will hopefully find your WIFI option working.
as i had the same.

Yes, it is well known that a first reboot is required to get WiFi working on CM7 right now. OP's question, however, is about the missing WiFi calling application.
OP, that's very interesting that it won't show up. So if you do a clean full wipe and install of something like RC1 or higher, you still don't get WiFi calling? Mine has been in there on every build... hmm..
I did'nt Wipe the Cache , I did the reset factory settings option. and install the CM7.0.0-RC1 with nightly version 2. and after done i found the wifi option is not working.
as i told when i rebooted the phone and i found the wifi option working.
Do you have a g2 or a desire z? I am looking at the changelog right now and it says that wifi calling is only installed on the g2. I'm assuming that you have a g2 since you are asking about it, but just throwing my 2 cents.
Maybe the rom is thinking that you are running a Z instead of a G2. Idk. It might help. More than likely not, but it's worth saying IMO.

I know what you are saying . but i tried everything after that i said so that wifi calling is working. as you find the WIFI connection then go the wifi calling app and then enable it and connect to tmobile network so that you can use it. but if you are in such area where Tmobile network's service is bad then might there be a chances to have no connection with wifi calling even if you have connected to wifi network (Internet)

now i am store working and i have a wifi at my job too. so i connect there carefully once again and checked everything and when i open to the wifi calling app and connect to T-Mobile Network for wifi calling i see after connecting to Tmobile via wifi radio signals turn to zero and when i disconnect it singals first had a 'x' on it and then they turn green. so make sure you are using the tmobile network then you will be able to use wifi option.

This goes under development because its a problem with my phone regarding the development so before the cyanogen rom release i had eugene's froyo5 and it worked fine.. well my fiance picked up the phone ****ed around with it and now no matter what 2.2 rom i use i can't get INTERNET sites to load or.. MARKET to sync my account or communicate this is with cyanogen rom and eugene's froyo6.. now my wifi will see connections connect and even gather info/ip addy from the wifi however it will not let me load pages ect.. now in 2.1 running the old RADIO + Slidemeroot5 or whatever it's called the stock with root it will go into the wifi/find/communincate and load my MARKET/INTERNET just fine.. so it has to be with a setting that would stay threw data/cache wipe with Cyanogen Kanged heres the thing.. I've wiped many times I've even tried restoring old backups from froyo5 they no longer let me sync/internet/market so.. anyone who can find a solution will receive an IMMEDIATE $20.00 donate and if done in a timely fashion an addition $10.00...
I will not be able to RE-ROOT or UN-ROOT my phone as i do not have my USB cable anymore

oppsy, I see some folks beat me to it and you need the at&t settings anyways. Just google at&t android apn settings. That should do it.
you will need proper APN setting for your carrier, google that shiz and you should be good to go, then you will just need to add the APN to your phone from that same screen
apns are different for each carrier, google APN <carrier> mytouch slide(or just android)

Huh? No data plan huh. Yeah, that will matter. Umm, so you have been using wifi to access internet right?
Okay from what I understand... wifi is real iffy with the 2.2 ports. You might have to select static and type in your ip settings from your pc. Just go on the pc and run command prompt and type ipconfig. That will tell your ip setting and enter them into the correct slots on your phone. Its under menu settings wireless& networks wifi settings menu advanced select static ip

yes I had wifi working fine on newslide.zip or myupdate.zip from eugene and all builds before in last 2 days wifis has stopped working... unknown why
Reread the first post. It says my WIFI will connect info and all that and above he states he doesn't have a data plan so its going to have to be wifi hes on.
Now I am having the same problem ever since I flashed the ROM and wiped twice and reflashed twice. Trying static IP now.
alas no luck on STATIC, question is why would I need to set up static when it should auto connect and auto know ya know? i'd like to be able to use WIFI outside of my home aswell
So right now it doesn't work on any rom now? If it's the cyan kernel, try dumfuq's oc kernel, I know it sounds strange but i tried one of cyan's kernel and somethings stopped working, led flashlight is one...Tried the new dumfuq and it worked for me. No promises though that it will work for your wifi problem.
your ip address of your router is 192.168.0.1 which means that your IP address of your phone will have to be 192.168.0.x since the computer is 192.168.0.199 i would try something around the 199 range(try going plus or minus 10) so either 192.168.0.189 or 192.168.0.209
also you will have to set subnet mask to 255.255.255.0 and gateway to 192.168.0.1

A good friend of mine waited to receive the OTA update of Froyo for his Incredible and when he got it he installed it. The bad part that I need help with is that when his phone rebooted it wouldn't allow the 3G data network to work. That section in settings is greyed out saying "Turning on..." and will not connect. The phone portion runs just fine. I have since returned the phone back to 2.1 and the same problem persists. If someone could help us out that would be awesome!!!
This probably wasn't posted in the right section...
I had an issue with 3G not connecting after downloading the froyo OTA off the internet and applying it as an update.zip.
I'm not sure if this is the same thing, but mine seemed to be that it wouldn't switch from the wifi network to the 3G network after getting out of range of the wifi (its set to auto connect to my home wifi, so it went straight to that after I rebooted it after the update). Then it wouldn't connect with the wifi off. I think I turned off both wifi and 3G and rebooted it with them off, and then turned back on 3G, and it worked. Everything is working normally now.
I'm not really sure why this would happen, I was wondering if it possibly had something to do with the phone registering itself after the update, and then not registering the 3G because it was on wifi and sort of "forgot?" That's just idle speculation though...
Also you might want to clear out your cache.
This might not be related to your problem, but I hope it helps!

Thanks for your effort, it did not work unfortunately.
Did he happen to have anything that controls 3G installed? Tasker? Juicedefender?
If he powered off while the data we disabled, and updated, then 3G won't work. Period.
I've heard of ways of restoring the APN or something, search the forums on that.

He did not have any type of app like that. He is a very novice user. I tried searching for restoring APN with no luck, anyone else?
When I first flashed Virtuous2.0 and did the initial setup, I didn't get 3G either. I'm pretty sure a good old fashioned *228 did the trick. I did have a backup through APN Backup & Restore, but didn't need to use it.
Have you tried turning on the airport mode, rebooting, turning off airport mode. Or perhaps do a *228?

Tried this too and no luck.
Go to Verizon and tell them to fix it fix fix it fix it! If he's running stock its nothing he did. Sounds super bunk that they finally got froyo only to not be able to use 3g.
The loss of 3g data is a bug with the froyo builds. All the froyo roms and the official ota have this issue.
sent from my Droid Incredible using XDA app.
this just happened to my friend too. I updated his phone last week with the OTA and since then he hasn't had 3g, but wifi would work.
did a rom manager backup before hand though, so i told him to revert back, and everything is working again. not sure why flashing back didn't work for you
So he hasn't had 3g at all? He can make calls and a *228 option # 1 doesn't update his settings and reboot? Maybe something when wrong on the install, whats hboot say?
Assuming he's completely stock I'd suggest going to the Verizon store and having them try.
Good morning,
I've been reading the forums for a while for solutions and tips but I am stumped on this one.
So I had stock Epic 4g (SPH-D700) on the Sprint network that was rooted and running CM 10.1 just fine. My USB connection broke so I bought a new motherboard so that I could switch to Cleartalk wireless, which required a connection for them to flash. They flashed the phone and while in stock, 3g data worked fine as well as phone calls and texting. Even stock though, with new motherboard, wifi did not work. It wouldn't even turn on to search for a connection. After rooting and flashing CM 10.1 while on the new Cleartalk network, 3g data now does not work and it gives me this error "unable to resolve host get.cm no address associated with hostname." Wifi still behaves the same. Calls and texts still work but I currently don't have any way to connect to the internet via 3g or wifi. Please help! I don't want to go back to stock just for connection.
Thank you!

Sounds like 2 issues here.
1. You probably forgot to connect the wifi antenna when you swapped motherboards.
2. You don't have your APNs configured for Cricket after flashing CM10.1.

1. I will double check this as soon as I can.
2. Any idea how I can go about configuring the APNs? I saw a solution where I backup the APN's with an app while in stock then restore once CM 10.1 is flashed. Will this work for me?

No problem. I will try some things and update this thread with the progress. Thanks again!
So it isn't the hardware connection for the wifi problem. I checked everything and it still didn't work. I even reinstalled the old motherboard to make sure I had all connections right and the wifi worked fine. I just discovered the Bluetooth also doesn't work.
I haven't tried repairing the APN yet, I will update after I try.
Using "APN Backup and Restore" did not work. The app runs and says it is successful but doesn't actually restore the APN's. Or it does and that isn't the problem.
Just reaching out to the community to see what they think is the best rom with wifi calling.
Using Jedi at the moment and it just had a wierd problem where it wont connect to the celluar network. Just shows that circle with a slash on it where the signal strengh should be. Wifi calling works fine on wifi. When i go to status it shows the modem as disabled. When i try toggling airplane mode on and off it briefly shows some signal strength before going back to the circle with the slash. Rebooting the phone sometimes makes the celluar network work fine for a bit but the problem returns quickly. Flashing a new modem didnt do anything. But a full wipe of the phone seems to have fixed the issue. So since i am in a wiped state i figured i would see if there is another rom i can try!
Sorry for the long post lol thanks!

Honestly Jedi Master IMO is My favorite Tmobile Based Rom. Your problem is weird. I would try wiping everthing System/data/cache/dalvikcache 3Xs and do Flash JediMaster again. In Aroma choose option to Retain Modem . When finished with Aroma Reboot and dont forget to let your phone settle for 10 min & Reboot. That should fix your problems
---------- Post added at 11:42 AM ---------- Previous post was at 11:39 AM ----------
Also this kinda goes in the Q&A and dont say "BEST ROM" every Dev works hard on there Roms with there own style. So its all in what you like. I Like JediX and Jedi Master IMO just my 2cents
I agree with @G7Baker on both avoiding terms like "best rom" and on your problem being weird. It sounds like it's resolved now, so that's good.
In the interest of keeping the list small I would say the most recently active (I use that term loosely - maybe "most recently updated" but that doesn't mean those that haven't been updated recently suffer from issues by any means) roms that offer wifi calling would be:
- Jedi Master
- NoteS4
- Malicious MD1
- Tweaked
Any of those should be fine if you are feeling a flash-itch, but as they say - if it's not broke don't fix it - your call of course
Tweaked is probably your *best* option given that "dwitherell" always provide very active support.

I had exactly the same problem using stock ROM where it would not switch to cellular for more then a second or two. Turned out the problem was that under the settings for the wifi calling app it was set to "never use cellular". Once i switrched this setting back to "wifi preferred" everything was business as usual.
Ah well, didnt mean literally the best since its subjective. But wanted to see what people liked.
I will be trying jedi again. I didnt realise he had 2 versions and installed the one without wifi calling at first lol
I like the s4 theme that it comes with and the beats and other lil tweaks. I have ver 14 and it seems ver 16 is out now.
Thanks for all the suggestions and i will keep that wifi option in mind for if it happens to me again.
Just wanted to thank the people that took the time to reply.

Go with tweaked rom. No issues. I use wifi calling all the time
I can't access mobile data.. 2G or 3G on my phone since yesterday. Earlier, there used to be occasional signal drops, but toggling mobile data, airplane mode, or rebooting would resume the connection. My APN and account balance etc are OK. Now, voice call and wifi work ok, but elsewise, the signal bars stay greyed out, and 3G, G, H or E indicators never show - it's as if it isn't even attempting to connect to data. :crying: I also had a problem with the toggles on the notification screen not updating... i.e. showing on even though i's turned off as shown in settings menu. I wiped dalvik and cache today... but again, no change.
I tried my sim on another handset and got connectivity, though a very slow connection. This is a peak mobiole usage time here, so bandwidth may be clogged, but no connection altogether?
Any help on how to get back data connectivity would be really appreciated.
Can you please tell me if there is any way to pinpoint if this is a network deficiency or a hardware or software issue? Can the radio malfunction for only mobile data leaving voice and WiFi intact?
I'm running:

Actually, I got back data connectivity once before I could flash BB85.. so most probably network was a factor.
Anyway... I managed to flash BB85, and connection is quite nice, except for the persistent issue of occasional mobile data drops -(toggles not updating) . Thanks!
By toggles not updating, what I mean is If I connect the phone to 2G - and leave it, sometimes the phone will show no data connection and greyed out signal bars, even though data quick toggle is on. If I turn it off, it will not grey out. If I turn on wifi, though, the data toggle finally turns off.. and turning it on after that reconnects 2G. Any idea what causes this?
