Cant get my t mobile wifi to work on my xbox one x phone is good

Hi, I hope you're doing great out there. I am an Independent advisor and I am here to help you with your concern.

May I ask what is the exact error or issue that you're getting whenever you're trying to connect your Xbox One X to your T mobile wifi?

Also, try performing an extended powercycle and reset the network hardware by following the steps below:

" 1. Unplug the power cable from the back of the router, modem, or gateway for 5 minutes. If you have a router and a modem, unplug the power cable from both devices.

2. Press and hold the Xbox button on your console for 10 seconds or until it turns off then wait for 2 minutes before turning it on again.

3. After 5 minutes, plug the modem or gateway in first, and wait for all the lights to return to their normal state.

4. If you are using a router, plug in the router and wait for all the lights to return to their normal state."

my xbox disconnects, but I think because of the mobile phones and wifi, but I turn my phone wifi off and it works fine, it it's not completed then I just click download again and it starts from there it finished.

I disconnected my computer from the internet and then plugged my phone into the computer and left the wifi on the phone on. this didn't work. ALTHOUGH, when I turned off my wifi and left my mobile data on the xbox app worked perfectly. I assume this means the issue is my internet.

I use a Seagate 2TB external HDD with my One X, and it is smaller than my mobile phone so can`t see there being any problem transporting it around.

I have the same issue with a Galaxy S10 phone that was working prior to most recent update.
I too am able to get it to work by setting to Airplane mode and then enabling WiFi.
I do have a second phone with a different carrier and that works with no trouble at all.
Here's some info if it helps the battle...

Working Phone:

Model: Samsung Galaxy S22 Ultra

Carrier: AT&T

Non Working with Mobile network active
Model: Samsung Galaxy S10

Carrier: Tracfone (Using Verizon network SIM card)
Tried changing Mobile Network Mode from LTE/3G/2G to Global and still failed

Tried changing Mobile Network Mode to 3G/2G and was able to get it to work, but phone wouldn't connect to network operator make calls on 3G/2G
I set back to original LTE/3G/2G and then disabled my WiFi and App is crashing at menu.

I turned off my Mobile Data, Still with WiFi disabled but connected to Mobile network for calls/texts, and the App did not crash. No Internet connection established, but the mobile network did not seem to play an issue, only the Mobile Data over the network.

Interestingly enough, when I go back to original setup (Wifi Connected, Mobile Data Active) App crashes, then I logged out of my GPU profile and the app stays active with no crashes but can't play games without signing in.... When I sign back in to GPU profile, app crashes.

Not sure if it's Tracfone or Verizon network specific, but the app crashing appears to be 100% related to GPU accounts being logged in. Hope this helps.
