    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
    http://m.gsmarena.com/samsung_galaxy_s5_cdma-6338.php

    T Mobile Galaxy S5's have completely different LTE bands.
    Look where it says G900T for LTE BANDS
    http://m.gsmarena.com/samsung_galaxy_s5-6033.php

    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.

    I bought a pair of unlocked T-mobile S6 edges off craigslist and have been using them on the AT&T network for nearly a year without issue (both have been rooted). Yesterday my wife's phone displayed a SIM error stating "network locked sim inserted" and prompted to run the device unlock app but I can't run the app without a T-mobile sim. I contacted Tmob customer service and they confirmed the device is already permanently unlocked on the server side and there was nothing else they could do. Also tried going to the Tmob store and getting a rep to put an active Tmob sim in the phone to try the device unlock approach but the app failed stating the device wasn't eligible to be unlocked (phone worked fine with the Tmob sim inserted).

    I've filled out the form from the OP. Hoping you can help.

    So , update after forever. I got unlocked with this method on 5.1.1 but have since upgraded to mm. I FINALLY tried another sim card since the upgrade and have also wiped and used different rom's several times. I did get bars but no 4g icon and no service. Wondering if maybe putting in sprints info - like instead of fast.tmo. whatever would work. I am not using sprint so don't need it to work but just wanted to report that.

    I'd SIM unlocked my phone thanks to stifilz, and it worked for months. However, I just upgraded its modem to the OK1 version and now it asks me for a SIM unlock code! Oh, and when I tap the Unlock button nothing happens... :S

    I tried to downgrade the modem to OJF but Odin gives an error saying the boot loader won't let it. I'd just upgraded the boot loader to OK1 as well...

    Any ideas?

    Thanks

    PHEW!!! It was heart-attack inducing, but I was finally able to get my unlock back :)

    Thankfully, I had an EFS and Modem backup through TWRP recovery. I restored it and everything's good again! :)
    Pretty sure I backed up efs. Upgraded to mm and seems I am relocked. What do I do flash the efs file in twrp?

    Just wanted to post here to say thanks to stifilz for unlocking my Galaxy S5.

    Bought the Sprint version to use in the UK and stifilz unlocked for me. Clear instructions provided and very fast unlock all done remotely.

    Thank again!

    Hi, yes, it is the same process to flash a ROM via Odin. Click on AP and select the ROM.

    If you're not experienced with Odin please make sure you do lots of reading! Ensure you have the correct file for your model (very important).

      OK guys enough. Take this to pm if you have issues.


      Now as a warning to every one. Allowing someone remote access to your device is dangerous. While I am not saying the OP is doing anything wrong but everyone should act with a degree of caution. IMEI numbers are stolen every day and used on illegal devices and then are black listed. So please everyone be careful.
