Will a Simple Mobile iPhone SE work with T-Mobile?

According to Simple Mobile's site, it actually uses T-mobile bands, and I do have a T-mobile SIM in service, and it has operating data. And plus I know that a Simple Mobile phone is locked to Simple Mobile, and it states it uses T-mobile, so if I buy their iPhone SE for $129 prepaid at Best Buy or Walmart, can I use a T-mobile SIM (NOTE IT HAS 6GB OF DATA EVERY MONTH, AND UNLIMITED TALK AND TEXT, IT IS NOT AN UNACTIVATED SIM, IT IS ACTIVE). There are people stating that it is very good, but I am curious if a standard T-mobile SIM would work with an iPhone SE on Simple Mobile? Here is proof that it is powered by T-mobile, and will that phone work with a T-mobile SIM, or I need Simple-Mobile?
