Anyone else having this issue?
I tried sending a message in a RCS group text but it failed. I turned off my WiFi and the message sent and I started receiving messages in the group.
This made me realize the problem, I texted the group to verify that they were seeing my messages, they were. Flipped WiFi on and off a few times to verify it was the issue. Anytime it’s on I can’t send or receive RCS messages
iPhone 15 Pro, iOS 26
I found a solution on my end, the problem was in the Wi-Fi settings.
When connected to my Wi-Fi network i always have "Private Wi-Fi Address" set to Off - with this
setting being like that, IMS drops the RCS registration when Wi-Fi is active.
As soon as i changed the setting to "Fixed" or "Rotating" - RCS Activated and works over Wi-Fi.
I'm having the same issue. RCS only works when my wifi is off. Once it's on wifi, RCS doesn't work. I checked my "Private Wi-Fi Address" setting and it's already on "Fixed" so lithualien's top-ranking solution unfortunately doesn't work for me. Any other suggestions or do I have to wait until Apple comes up with an iOs update to fix this issue?
Can you elaborate on why you shared a link to that article? I do not see any helpful information there.
Also what do you mean "re-registered my e911 address" - the article does not mention e911 anywhere nor any other troubleshooting steps.
Anyone find a fix for this?
You should not have to do that!
I also have this issue. RCS doesn’t work while WiFi on. It only works when WiFi is turned off.
Good find. That worked for me too.
this worked for me
im glad it worked for someone too :))
I just tried again and it seems to be working. Thanks!
Thanks I got it working now!
This solution also worked for me. iPhone 17 pro iOS 26.0.1 on Verizon & Quantum.
This was the solution to getting it to work for me, it was NordVPN. RCS wouldn't work, and my wife's phone calls would always go straight to voicemail. None of the other suggestions fixed it for me, but once I disabled the VPN and gave it a minute, everything started working again.
Very strange that this setup, NordVPN and T-Mobile wi-fi calling/RCS, worked perfectly fine in ios 18, and is completely broken in ios 26, because the moment I upgraded is when everything stopped working.
