    need help.
    Bought a note 10+ from best buy unlocked..
    Unlocked to what I remember is sim unlocked and carrier unlocked.
    You can not call Best Buy and ask them nothing.

    I got a friend telling me if I have a CDMA phone.
    It will not work on T-Mobile network,, because it's GSM.

    He's telling me they don't make a phone that will work on CDMA and GSM both.
    I can't remember.
    Can anybody help me answer this question.

    Thank you.

    it is important to know whether your galaxy note or S is categorized as GSM or CDMA. I have a S10 plus that is a GSM phone. and is on T mobile carrier. most galaxy phones are GSM phones. if the phone is CDMA It can only be use with verizon

    If it's an unlocked Note 10 it should support both
