LTE+ on TMobile?

[CKwik240]

So I was getting some labeled done today and while waiting, I noticed the 5G symbol disappeared and it was displaying LTE+. Curious as I was some I had never seen that on any phones with TMobile, I ran a speed test and got about 100mb/s down. Anyone know if this is a Sprint thing that we now have access to? So far this merger seems to really be benefiting me on TMobile.

I have tmobile and have only seen the 5g and 4glte symbols never saw the +. I always chat with tmobile when I have a question super easy and convenient and better than a phone call.
