I recently purchased a Galaxy S9+ for my Xfinity Mobile account. After looking at the details of the S9+ I realize it is a CDMA network. I thought that since my S9+ had a sims chip it would be GMA and not CDMA. I'm not sure how to tell what you get until you get it when the network format or with the SIMS. Is there multiple S9+'s that can be GSM or CDMA? I just hope my S9+ will be valid for awhile since Xfinity uses Verizon network and they are fazing out CDMA. Also how do you tell is it is LTE or 4GL or 5GL? This is very confusing and I have a computer background you would think I would know this stuff.
