Sprint S9 on TMobile bloatware keep?

[InterstellarShield]

As the title indicates I was given a Sprint S9 (unlocked as all models I read were for N.A?) The phone has an insane amount of bloatware for Sprint. I am wondering if I need to get rid of it all or are there certain ones I have to keep?

 

The phone still is "registered" to the prior number as I saw in the contacts under "Me" or the voicemail number. I know a factory reset did not kill off this information.

 

I do know I had to jump through a few hoops to get my Verizon S7 to work on T-Mobile store network, but I was wanting to see if anyone had valuable inputs that may help me out.

 

 

****ALSO should I factory reset the phone, and add my existing profiles form Google, Samsung etc in the beginning, or will smart switch do that for me? 

 

TIA!
