I bought a Samsung Note 5 online which supposedly supports GSm and CDMA. I went to Verizon and got a CMDA SIM card installed. The data service I get is awful so I have researched this and under networks it should show global, cdma/lte. All I show is 2G, 2G/3G and 2G/3G/4G. Why don't I get the other options? what is different about my phone? I have read everything I can about the different networks and can't figure this out. I'm an EE so I am not clueless about these things. The power level I was getting has been around -109 dbm and asu of 1. I added the Verizon APN and turned on roaming, made sure airplane mode is off etc.... I did get some improvement by changing some settings under "developer mode" but it bugs me that I don't the those 2 network settings available. HELP?
