I upgraded to the latest update on 6/14 and that was supposed to fix WiFi issues but to no avail. My phone happily sleeps and does not take incoming calls on WiFi but the interesting thing is that it immediately notifies me with a visual voicemail or text message over the same damn WiFi. It is not the router issue as my wife uses Samsung SII and it works perfectly fine over the WiFi. Not sure how a flagship phone that got released after such delay can still be buggy.
I too have same issues sometime even on the mobile network. I am new so don't knwo who to approach.
Before I can troubleshoot this issue I do need to know if you are not able to make WiFi calls, or if you are not able to make any calls while WiFi is enabled. Visual Voicemail is capable of coming through on data, and text messages come in through the phone towers, so having issues with your WiFi doesn’t mean that there ought to be issues with receiving notifications.
Please come back with that information so we can look into this issue together, or any alternatives that you find.
Hello, I am also experiencing such issues. I am unable to make or receive calls after sometimes and then I have to restart my phone again for me to make or receive call also my data connection drops after few mins of usage. Please help us to solve these problems.
I seem to have the same problems as well. I set the phone as 'prefer wifi' over mobile network for calling, so when i'm on wifi, it looks like my mobile antenna goes away altogether. I can make crystal clear calls over wifi, but it apears i cannot receive incoming calls --- but i do get voicemail alerts (this happened just yesterday) almost instantly, because when i called back they were surprised i called back so quickly.
Also worth noting the first time i turn on my phone each time, while the phone is booting, it is not uncommon to see a red wifi calling logo which says invalid sim card, but after about 1-2 minutes once it is booted up entirely the wifi calling logo in the notification area turns blue and wifi calling works.
The problems must be intermittent, because it worked at least once today.
I have the same issue with wifi calling. I can place a call with wifi calling however it does not normally ring on my end. I just have to wait for the voicemail or person to answer to tell if it went through. I can only receive calls if I am currently on another call or within 2 mins of hanging up from a call. After about 2 mins its like the line closed and everyone gets sent to voicemail. I noticed that my airplane mode does something wierd the second wifi calling is active. In the settings it says airplane mode turning off and its grayed out so you can not touch it. I was told that it just appears to be on but if you click the power button who can see its off. However I refuse to believe such a claim due to the fact that I can be on a call with my bluetooth walk into my house my phone will auto connect to wifi calling and the second it does my bluetooth beeps telling me I have lost signal. I have been sent 2 replacement phones from my cell company within 3 days of each other, Every phone does the exact same thing. It appears that if I am on a call or recently have hung up my phone has a open line or does not recognize airplane mode but within a few mins its like it closes and no calls can come through. Of course thats just my theory but its more research than my cell phone company put into fixing my problem.
The problem is not a matter of phone service, the root of the problem is the wi-fi connection tend to shut off by itself. It has been happening to me too.
Agreed that Ii have the same problems with WiFi calling.
1. Missed received calls
2. Long delay in voice from talker to far end.
I had my wireless network set up properly for Blackberry 9900 WiFi calling, and also I can call out on the HTC Ons S, and receive SMS/MMS.
The root problem I see is that the phone WiFi sometimes appears to disconnect, or take a long time to re-connect.
- WiFi "Advanced" setting: Keep WiFi connected during Sleep is Enabled
If I PING the HTC device, if it has been asleep (screen off) for more than 60 to 120 seconds, oftenn times the first 2 pings fail, and after a while the 3rd or fourth ping gets through with 600-1500ms response delay.
One workaround is to enable "WiFi Best Performance" in advanced WiFi settings, but that totally clobbers the battery life. It is unusable since battery dies in a short time at that setting.
WiFi calling and phone features need work, HTC! The rest of the device is awesome. Please fix.

Thanks for the information everybody. This all helps to troubleshoot some of these WiFi issues.
NokiaFan’s suggestion to keep WiFi connected during Sleep is a solid one. I’d also suggest toggling your WiFi off/on and see if that has an effect. If you’re still experiencing problems then I recommend soft resetting the phone by powering the phone down and removing the battery for about a minute before putting it back in and starting the phone back up. This will refresh your phone completely, and may help with the WiFi calling issues. Another thing to look into is the WiFi connection’s router, which may need to be power cycled by unplugging the connection for about a minute before restarting it. This could stabilize your WiFi connection, which could resolve the connection issues.
If you’re still having trouble then I recommend going to the Google Play store and finding another WiFi Calling app to see if it works better than the one you are currently using. You can either open the Play Store app on your phone, or you can go to the Google Play website which can be found here: play.google.com from your phone or from your computer.
If you’re still having trouble after all of these steps, then I recommend contacting my teammates in Customer Support. You can find their information at www.htc.com/support.
Please post back with any questions or progress that you have.
Corey I was excited when I had seen your troubleshooting ideas, and have unforutnately not had any of them work. I am having the entire problem list that each person has listed. I believe after multiple hours (up and towards the near 60) spent with tmobile customer serice, the Foundation issue is the actual WiFi connection in the phone. I have changed my wifi calling app, changed the sleep mode, all of those things, the thing I noticed one time is that my wifi slider in my "recent app" section was slid to off on the screen shot so I chose the "recent app" and when the screen appeared the slider immediately moved and my wifi started working again. I have even troubleshooted the "idea" that maybe the network and the wifi are "battling" for the phone connection so I have turned off the network and anything to do with the phone system except for wifi, and I cannot even at that time view the things I am trying to, It will work for about the first 3-5 mins after I turn wifi on, then after that I have to toggle back to the wifi settings turn off wifi and then re-connect. I hope this helps with a determination as to how there can somehow be a fix for this
The only thing that worked to improve things is to work-around an apparent bug in the phone.
The work-around totally kills my battery life, but it at least made WiFi calling a little more reliabe:
Set WiFi advanced Settings: Enable "Best WiFi Performance"
The root cause, as you point out, is the default settings of the phone make the phone WiFi disconnect from the WiFi network when phone goes to sleep. EVEN if "Keep Connected" is enabled.
Again, this is a work-around that, hopefully, if any HTC employee is reading this, will be addressed.
This does not fix the DELAY in the calls (near end to far end delay), but at least it should let you receive calls.
HTC, PLEASE FIX WIFI CALLING!
