It seems like there is no clear difference between the three. I have a Verizon 8X and have had "Roaming Service" issues. I tried switching the network mode from global to LTE and CDMA. Then, after using HTC's Connection Setup, the "Roaming Service" seemed to stop. So, thinking it was safe to switch back to global mode, I got "Roaming Service" again. So I am back on LTE and CDMA. However, what is the difference between the two, and why does my network work better on one than the other? (I also tried using Connection Setup on global mode to no avail)
Edit: As soon as I started this thread, I realized that on LTE and CDMA I get "Roaming Service" again! This is super frustrating!!
