T-Mobile customer and a OnePlus customer for a long time. Enjoy grandfathered in pricing with T-Mobile on the magenta military plan.

Finally dropped my 8T too much, and ordered a 13. Not wanting to wait for a new sim or go to a physical store for sales pitch, I said I'll just use the esim capability on the OnePlus 13... Or so I thought.

About 9:00 a.m. this morning I put in for the transfer through the T-Mobile interface for my T-Mobile account. Pretty smooth first it asked me for the IMEI, validated as a OnePlus 13, then it asked me for the EID (which makes sense because I indicated I was transferring to an esim), everything look good request completed I got the message to leave Wi-Fi connected and that it hey it might take 2 hours.

Shortly there after I got an email from T-Mobile saying hey it's complete good to go. Except it was not. I called them thinking I would get them to email me the QR code to type in based on some Google I did....

What I did get, was first someone telling me it was only a 2G phone the one plus 13, then I got a different person telling me it was not esim capable. Double checked a lot of things and messaged through the web app back to customer support (had to do that because of course the physical Sim that exists in the 8T was deactivated as soon as the transfer request went through)

T-Mobile acknowledged the OnePlus 13 is e-sim capable, they acknowledge that it's just incompatible with T-Mobile on esim. I verbalize the transfer request interface step by step, in short saying that you gave me no warning you knew I was requesting transfer to esim, and you knew, as did I that the physical Sim would be deactivated the moment the request went through, customer service rep "that is correct"

I have spent a lot of time being pissed off this afternoon.

Can I get some ideas on different cell phone companies to go with in the Western United States think Nevada Utah Wyoming area?

The second thing is this is a coding issue right like a decision by T-Mobile to not be compatible? Why? And why would they not provide that information to the customer until after the Sim was deactivated from a transfer request? What are they hoping I'm going to wander into a physical store and listen to a sales pitch and buy one of their phones instead? The way I see it they bricked my phone.

Finally I requested okay can you just overnight me another physical sim then .."we cannot assist you with this online". That point I just stopped talking to them before I got very very rude.
 
Or does anyone know a good contact email for T-Mobile that will actually get a response other than "can't help you"?

I would love to call a store and ask some questions or call tech support as the CSR from T-Mobile suggested but I can't because I don't have mobile network access
 
Update:

OnePlus 13 does work with esim and T-Mobile you may have to contact the Facebook social media account

Went through a lot of back and forth with customer service through the T-Mobile website today. Telling me it was only a 2G phone it wouldn't work then they told me it wasn't esim compatible. Finally we settled on it was compatible it just didn't work with T-Mobile.

The website customer service doesn't know how

The Facebook Messenger account of T-Mobile did.

2 Steps:

1) They register your EID
2) Email you the QR code that you scan with the OP13

Done
Took maybe 60 seconds for the phone to download the package and get rolling, and there was three or four minutes maybe of switching Network protocols bars going to Max and then to nothing and then it's done.

I had a similar problem with Visible when I went to activate my OnePlus Open. This was when it was very new to the market, similar to your situation. However, online support was able to overnight me a physical SIM. And I see now that the Open is listed by them as eSIM-compatible. Seems like it is either a problem with new phones or phones they don't sell.
