Best Unlocked iPhone Xs Max for use on T-Mobile



    I am looking to buy a used iPhone Xs Max for use on T-mobile but want to make sure I get all the features and call quality that t-mobile

    Is there any difference between the Factory Unlocked, At&t Unlocked or Verizon Unlocked for use on t-mobile network?

    I am trying to find the best deal and if that is not a t-mobile version then want to know which to get.


    Thank you in advance for any info.
