Your phone did not come out of the box capable of the proper bands to use it on the Metro PCS / T Mobile network. In fact, those 2 carriers are the same company.
Here are the specs for your phone, as it came out of the box.
Look where it says G900P for LTE BANDS

T Mobile Galaxy S5's have completely different LTE bands.

There are ways to add/change LTE bands, because all of these Radios are capable of the same RX/TX.
Samsung makes all of these phones with all the same parts.
The only exception being the different processors in different regions of the world at one point. They still all had the same hardware capabilities for their radios. Which means that they all had the same chips, Just different firmware (firmware is software that is stored on and runs off the phone's internal memory) .
They are specifically designed to make it as difficult as possible to move from one carrier to the other in many instances. CDMA carriers like Sprint and Verizon especially make it difficult to use anywhere else. Add we see here, this Sprint phone is not enabled with the proper bands in order to work on T Mobile or AT&T properly with data connections.
And now that you've unlocked a Sprint phone in this manner, It may never be capable of GSM 4G without a complete overhaul.
I Even did a Sprint device that was completely capable of all the right babe to move to AT&T, a Sprint Note 5. It had all the right bands in all the right places. But after unlocking in this way from Sprint, it can't get 4G at all. Add far as data speed, It's capabilities are stripped down to a 90's flip phone, at 1Mbps according to Ookla.
I actually have a phone repair business, it's what I do for a living. I thought stifilz and I could go into business together. And we still might for T Mobile, but Sprint phones unlocked by this method are not working on 4G, when if they had been unlocked by code, or a different method, they would have worked perfect on 4G.
There is something about this process with SPRINT PHONES that is clipping the 4G capabilities.
Keep in mind, this process is COMPLETELY DIFFERENT than when he does it for T Mobile, and T Mobile phones have had no problems as far as I know.
After 3 months of putting the Sprint SGS5 project to the wayside, I decided to purchase an unlocked AT&T motherboard from a broken SGS5 on ebay for $40 and remove the screen from the Sprint SGS5 to make activating it a whole lot easier and now I successfully got my phone working w/ metroPCS.
