Home Internet & Wifi calling

Thanks for your update. Much appreciated. Glad you got a straight answer. Your input appears to confirm that it's a firmware issue. Hopefully they'll get it fixed soon. For those of us with phones on TMO, it should be less of a problem since if the Gateway has a good signal, so should our phones. Nevertheless, it should work.

I have the same issue with Wi-Fi Calling and the Sagemcom gateway. I called TMHI support and the expert acknowledged that there was a problem with this gateway and Wi-Fi Calling. Regardless of how you connect to the gateway (its own wireless SSIDs or your own router), Wi-Fi Calling does not work. Suggestion for immediate workaround is to turn off Wi-Fi Calling until T-Mobile releases an updated firmware fix for this gateway. No ETA was provided.

Not sure if this helps those who have weak T-Mobile signal in most areas of their home but at least there is an acknowledgment of the problem with a promise that a solution is pending.

This is my 2nd time subscribing to TMHI and can confirm that Wi-Fi Calling did work the 1st time with the Nokia gateway.

If anyone finds a solution to this problem, please post it for the rest of us. Gracias.

My Pixel 6 on T-Mobile is unable to use Wi-Fi calling when connected to the newest Home Internet Gateway (Sagemcom Fast 5688W). I've been using Wi-Fi calling with multiple phones, on multiple Wi-Fi networks, all with TMo cell service since 2007. It worked perfectly on Spectrum. Since switching, I'm not able to receive calls using Wi-Fi calling. I had to "toggle off" Wi-Fi calling and then...all is right in the world again. It doesn't work when I use my personal router plugged into the Gateway either. A next level TMo customer service guy checked everything he could from his end and confirmed that "all was as it should be" and said they were unaware of this being an issue. I'm guessing this can be fixed with a Firmware update. Can I live without it? Sure, but shouldn't it just work? I wish TMo would pass this thread on to the responsible department. I've been with TMo since 2004 and I still think these guys are the best.

Same problem as everyone else. Just got a new T-Mobile gateway for home internet. Internet speed is great and has 4 bars in its current location. Wi-Fi calling will sporadically work but not reliably and it will drop calls. It worked perfectly fine with my Comcast router using the same phones. Both iPhone 11 and iPhone 13 Pro experiencing the exact same issue. I have turned off Wi-Fi calling because it is more reliable even with 1-2 bars in my house, but I wish this would be fixed. After a year of this issue being overlooked, my guess is we'll live with it or move onto another service provider. 

Yes does not work.  I have tmobile as a carrier on my phones and tmobile home internet… can't call with wifi calling.  I called tech support and they were working with me but they did not get a setup and try it themselves. 

What did work is if i connect to the wifi with my old google pixel 4a then via hotspot attach to the pixel 4a then I can call over wifi.  I can use wifi calling with every other wifi I have tried…. Cox and Century link.  NO problems with either with the same phone (pixel 6A).  Also my kids cannot wifi call with tmobile home internet on apple 11's and 14.

This is a big issue…. they need to first admit there is a problem then they need to fix.

Any updates on this? We just got the 5G home internet and it's fantastic! But the Wi-Fi calling issue is just that… an issue. We use Cricket Wireless which runs off of AT&T 

I am having this issue quite frequently and drop calls constantly with the t-mobile gateway router -- every day multiple times per day when I'm within our home.  Wifi calling is enabled on my phone, but appears to not functioning with our t-mobile internet.  Texting is also an issue when on wifi.  I have Verizon cellular service (rural midwest) and an iPhone 14 Max Pro.  Everything works perfectly outside the 4 walls of our home.  Oddly, other family members have Verizon service as well and seem to not be having the same issue. 

Happy to know it's not just me but frustrated to hear it's an ongoing issue with seemingly no fix.  We may just have to cancel our t-mobile internet service (which is sad as it has been performing perfectly for us in all other ways).  

This thread has been going for a while!

I've googled this issue for hours.  Is there a fix?

The engineers were aware over a year ago and haven’t addressed it?

I am experiencing the same issue with my AT&T iPhone 13 Pro Max.  I have the T-Mobile 5g home internet gateway, with "the latest" firmware for it.  When I do speed tests from my phone I Wi-Fi- I test at 300mbps download and 50mbps upload.  
 

When my Wi-Fi calling is on (since my AT&T phone signal is only 1 or 2 bars I my area), I can make and receive phone calls… but the calls ALWAYS drop randomly… and also- when attempting to send texts messages with AND without pictures…. I sometimes have to retry- because it fails the first couple of tries. 
 

It happens A LOT more frequently on my Wife’s AT&T iPhone XR… 

Any idea of a setting / fix for this?
