I have an iPhone 7 plus through tmobile and they network locked it. If I get a code to unlock with you all can I continue to use it on tmobile or will it not work with them because it was locked by them?

If the device is just network locked (not blacklisted by T-Mobile) after unlocking it will still be usable with T-Mobile.
This is official unlocking procedure. Network unlocking your iPhone 7 Plus using our service is permanent and no functions of the device will be affected (including OTA updates).
