I have the opportunity of getting a Samsung Note 20 Ultra from either T-Mobile or Unlocked and would like to know the advantages and disadvantages for each. I am not interested in flashing my phone (please don't kick me out of this forum) and I don't travel internationally as much as I once did (but who does these days), but despite this I am still intrigued by an unlocked phone. However, I have heard that the unlocked T-Mobile does not support RCS chat, even when the unlocked model is bought from T-Mobile. Any truth to the rumors and what do all guys know and recommend?
