Verizon Samsung Core Prime # SM-G360V To use on T-Mobile


    I recently got a Samsung Core Prime from a friend of mine and trying to get it to work on my  T-Mobile sim card is like pulling teeth. I get that I needed to add the information as stated . I did that , The APN and everything else but it still doesn't dial out or anything . The only thing that I can find on it, is that the band mode switch is greyed out and won't change from LTE/CDMA . I don't know if that's what is causing it or not . It still says that the sim is not recognized or something of that sort but as I understand it they all say that . I don't know if I have to reset the phone to get the mode band switch to work or if this phone does not have the capability of switching ? Who knows ?  Please help.
