WiFi calling frequent drops and call failed issues

Re: WiFi calling frequent drops and call failed issues

Have only had the phones ported since the beginning of the week, so it’s early. Yes, very poor signal at home, frequent dropped calls without WiFi calling. Not one problem in WiFi calling so far on the “good phone”, but WiFi calling worthless on the other. The main difference between the two phones is that the “good” one has many fewer apps on it. Maybe there is app conflict. No idea. But need a fix for this WiFi calling anyway.

Re: WiFi calling frequent drops and call failed issues

Hi Ken, I reading all the posts and I am having the same exact issue with 2 iPhone 6s Plus. Make and receiving a call is almost impossible. Xfinity mobile service is a disaster. I’ve called multiple times and it seems the only real fix is to switch carriers. I’m still currently with xm but I don’t know how much more I can take. Xm really needs to acknowledge this issue and fix it ASAP

Just curious... were both phones purchased at the same time/place? Were they ported over to XM or bought at Comcast store?

 

Makes me curious if a new iPhone X without any new apps would work fine or not, but I'm not willing to wipe my phone to find out.

 

I wish this could somehow be brought to the attention of the people who are working on this issue, as maybe there's a clue in there somewhere. Any ideas,

Re: WiFi calling frequent drops and call failed issues

Both phones were purchased at the same time, and both were ported from T Mobile at the same time. There is definitely something to that. The “good phone” has many fewer apps on it. I agree it would be very helpful for someone to restore a “bad” phone to factory settings as a “new phone” without any apps installed, to see if that fixes the issue.

We are now looking at other carriers. Sorry Comcast but you CAN'T fix your own problems.

DreamSayerZ, are you also having issue with connectivity outside of wiFi calling on other devices? I

Just switched from AT&T to comcast 2 weeks ago (July24th).  Have poor cellular reception at my house and had a Microcell thru AT&T.   Since the switch to Comcast need to rely on WiFi calling but unfortunately I have experienced a lot of dropped calls.  Is there a fix?

Re: WiFi calling frequent drops and call failed issues

Sorry, no fix yet. The only workaround is to put your phone in airplane mode at home. Has been flawless this way for many of us, but of course this is only a bandaid and you have to remember to turn airplane mode off when you leave the house.

In all fairness, airplane mode does not work flawlessly for many of us.

 

I've had to switch to Google voice for important calls at home -- until either (a) there's a fix, or (b) I change back to a reputable carrier

In all seriousness, coming from someone who has read every post on this thread, your choices are:

1) Try airplane mode

2) Add Google voice onto your phone and use that number instead

3) Switch carriers

4) Wait for a fix (hasn't happened in the 16 month lifetime of this thread)

Re: WiFi calling frequent drops and call failed issues

I don’t know if anyone has tried restoring iPhone as a “new phone” (not backup) And trying WiFi calling before any apps are reinstalled. Yes that would be a drastic step.
Contributor

Re: WiFi calling frequent drops and call failed issues

I would try that, but it would be useless, as my cell reception here has improved dramatically in the past 6 months. I would be very interested in the results if someone else gave it a shot.

 

I'm also still very much hoping for wifi calling - I think it's a great feature even when you don't absolutely need it, for reasons such as call quality, battery life, and a less powerful radio signal required.

I restored, set up as new, didn’t install any additional apps, and the problem still existed.

Re: WiFi calling frequent drops and call failed issues

Was this a phone that was previously used with a different carrier’s WiFi calling on the same WiFi network? (Some WiFi networks seems to cause dropped calls for all carriers in my experience)

Re: WiFi calling frequent drops and call failed issues

I'm amazed to look at this over one year thread seeing the poor WiFi calling performance on Xfinity.  We switched over from Verizon and all the family phones now have call failures associated with WiFi handoff from LTE.  We have poor Verizon coverage at our home so using a more robust WiFi signal at home for solid phone calls is essential.  This should be considered mature technology and for the issue to continue for more than a year is disturbing.   I know there are specific carrier specific conformance testing for AT&T, Verizon that the iphone engineers go through.  You would think that Xfinity using Verizon would work seamlessly but that is not the case.

Re: WiFi calling frequent drops and call failed issues

For those having WiFi calling issues, are you using Comcast leased modem/router or are you using your own dedicated modem/router/WiFi?  I have my own purchased modem with a seperate router and WiFi.  We have solid 300M download and 12M upload, with very good 300M WiFi coverage through the house.  I never had call drop issues when we used Verizon Mobile directly.  Now that we switched to Xfinity Mobile we have constant call drops.  Is there any correlation with others having the issue associated with using private owned modem/routers versus Comcast leased equipment?

Re: WiFi calling frequent drops and call failed issues

I have tested my WiFi calling on multiple different devices, purchase and rental. All modems have gig service, and one is an EPON which is a fiber connection all the way to Comcast backbone, minus the 5-10 feet of 5ghz WiFi, which I sit next to at work. I have constant issues with dropped calls. Sometimes they work, but more often than not, they fail.

Using Comcast leased cable modem but own mesh router. Also excellent WiFi signal throughout.
These failed calls have also happened at other commercial and residential using WiFi calling.

Re: WiFi calling frequent drops and call failed issues

It doesn’t matter what modem which Iphone. Same thing. It’s 100% xfinity’s problem. I’ve been dealing with this for almost a year and tried everything and checked everything. Nothing has worked for me to solve it. Seems like they aren’t even trying to do anything

Re: WiFi calling frequent drops and call failed issues

I was one of the people who came from Verizon, and struggled with Xfinity WiFi calling for 9 months. I tried EVERYTHING in this thread (including phone factory reset, airplane mode, new router,....).
I had technicians over to measure out WiFi and Cell signals in my house.

I had tickets with Verizon and Apple.

I wrote to the CEO of Xfinity, and got “executive personal support”.
All of this lead to the conclusion: WiFi calling with Xfinity does not work. Xfinity’s problem, and engineering isn’t even working on it!!!

So now 3 months ago, I switched to T-Mobile. Since I am 55+, I get two lines unlimited EVERTHING (data, text, calling,...), even unlimited data and text in over 200 other countries... I stream Pandora in my car (UNLIMITED), I FaceTime my friends and family from the beach, ...
For $90 (which includes my Netflix account, all fees and taxes,....).


I am not looking back: not a single dropped call, service where I didn’t have service before, and more perks than I can handle...

Well, I guess I did look back, because my inbox is still overflowing with forum chatter. But it is the same old, same old: don’t botter, it is Xfinity’s issue, and they’re NOT working to fix it. And there is NO work around (even Airplane mode fails).

Re: WiFi calling frequent drops and call failed issues

Xfinity Mobile is a MVNO, Mobile Virtual Network Operator.  They advertise and tell you at the store the same quality as the primary carrier...Verizon.  Well, as we all experience that is not the case.  I even found on the web an article comparing service quality of MVNO's versus the primary carrier and found that Xfinity Mobile is about half the quality score when compared to Verizon directly.  This is dissapointing after switching 4 family phones.  I think I will start demanding half off my bill until they fix this, or just switch back to Verizon.  Switching back would be a hassle as we did some phone upgrades at the store.

Re: WiFi calling frequent drops and call failed issues

I must say it’s a much better experience reading this thread as a former Xfinity Mobile customer rather than a current one.
Switched to Sprint Kickstarter 2 lines unlimited for $50 per month. No dropped calls since switching.

Re: WiFi calling frequent drops and call failed issues

Success.  I went back to calling Xfinity Mobile and got Tier 2 support on the line.  I explained one of our iPhones 7s was dropping calls and would not reliably default to WiFi calling at our home where we have very poor cell coverage (in between two Verizon cells with a hilly terrain).  The phone should camp on WiFi, but calls drop and the quality is not HD calling.

Matthew at Xfinity checked a few settings and then directed me to turn of "WiFi Assist".  This sounds very counter intuitive, but appears to have worked.  Go to "Settings" > "General" > "Cellular" and then scroll was down to the bottom and and find "WiFi Assist"....which is likely enabled, and turn it off.

 

After we did that he called me on that phone and I walked our house to all areas and the phone call was solid, on WiFi calling the entire time.

 

The rest of our family will try this on our phones and see if it works.  So far this seems to resolve the issue.

I've had WiFi assist turned off for many months. Give it more than a day....I've noticed WiFi calling has a good day once in a while.

Re: WiFi calling frequent drops and call failed issues

My wifi assist is off and I called all tires of available support including techs at the house. Most of us here tried it all. Read the whole thread, it’s I believe 2 years old or close to it. NOTHING WORKS.
You can stop wasting your time. What’s absurd is that this company can still pull clients in, and not disclosing that their product does not work properly. It should be clearly stated when signing up or buying their IPhones that if you plan on using WIFI calling feature, you will have problems.
How is this legal is beyond me.

Re: WiFi calling frequent drops and call failed issues

Well, turning off WiFi Assist had no impact.  Still problems.  I called support, started a call, but the call dropped.  My patience is running thin.  It's time to start requiring monthly bill credits until they get this fixed.

Re: WiFi calling frequent drops and call failed issues

It's quite sad that there are so many customers on this forum willing to help find a solution to try to make this service work...yet there's absolutely nothing to show for it.

 

The only redeeming virtue is pointing folks contemplating switching to XM to this forum before they get drawn in.
