No wi-fi calling on t-mobile since installing spitz AX GL-X3000

[gainestr]

I have found on several forums that WiFi calling needs to have WMM turned on in the routers QOS settings. There is no option to enable WMM or QOS services on the GL-X3000. Some router manufacturers even have an option when setting up the cellular connection to “enable WiFi calling over T-Mobile” so apparently their is a fix for this issue and it’s a known one with other manufacturers as well. This seems to only be an issue when connected to 5G SA(Standalone) towers. No need to reply with “mine works” if you are connected to 5G NSA networks or a combination of LTE networks.

Is there a plugin that the X3000 can use to enable QOS and WMM that will work on this router?

FYI,

T-Mobile and 464XLAT

You can add under the /etc/config/network file, configure as follows, config interface ‘wan6_4’ option proto ‘464xlat’ option ip6prefix ‘dd50:e735:b42d:1111::/96’ and then execute cmd: /etc/init.d/network restart Option ip6prefix is just an example. This is the ipv6 prefix of a NAT64 server. It is usually provided by the operator. You can ask the operator.

IPv6 when using 5G SA on T-Mobile

Native or Passthrough, because these two modes can get the global unicast address. But I’m not sure if T-Moblie supports dhpcv6-pd, so you can try using native first and then passthrough if your lan device can’t get ipv6.

WMM may not be necessary as the OP didn’t touch WMM settings.

There seems to be a proper fix for this now without having to use wireguard. Now the programmers just need to implement a fix for this in a future firmware.

T-Mobile Wifi calling NOT working

I bought a new GL-X3000 and installed a T-Mobile SIM card. We use it in our RV while camping. The data works great. Speeds up to 200+ so no issues there. However, I cannot make/receive any calls on my IPhone (via Wifi calling). What is weird, is that my Android (Samsung) phone works. I tried to turn on IPv6 and that did not help, other than drastically slow down my data speeds. Any tips or recommendations to have Wifi Calling on my IPhone with T-Mobile? TIA!!!

I have a simpler solution that seems to have worked for me to fix the problem. Just follow this guide to upgrade the firmware on the 5g modem itself.

Upgrade Quectel Module Software - GL.iNet Router Docs 4 (gl-inet.com)

Once I was able to do this, the IP4 and IP6 addresses populated and I was able to do wifi calling without using a VPN. I do also have the 464XLAT installed but I'm not sure if that's also important or not. I guess someone that didn't install it can report if wifi calling just works once the cellular modem is updated.

Again, this is NOT a router firmware update. This is an update for the firmware for the cellular modem inside the router.

cold0ero Thank you for the suggestion. For now all is working well with the earlier suggestions implemented. Should I have problems in the future, though, I will keep this handy.

Yes, newer modem firmware corrects the issue without having to do anything else. Thank you for bringing this topic back up. Much easier solution now.
