Can I buy a phone from somewhere else and switch it over to MetroPCS?

I was wondering if I was to buy  the Samsung Galaxy s9+ from another store due to y'all only having the s9 would I be able to switch the phone over to metro even  though y'all don't carry it?

Hi Angel. Where will you buy the phone? I checked Samsung Galaxy S8+ and it works with MetroPCS so my best now is Galaxy S9 will do too.
