========================================
Alright guys, I have bought myself an Asus ROG Phone 5s ZS676KS and it works great in hardware sense except for connectivity to GSM networks in the US. I can verify that the phone is the issue as I have tried on multiple GSM networks with no avail. I am now on Tmobile which besides Verizon(CDMA) has the best connectivity in my area. I have learned that other people on other phones with Tmobile often have service even if I don't. Me being a young IT guy have looked into the Mobile Data settings to find that the APN Settings were correct and even after doing all basic troubleshooting to eliminate all simple issues. The Manually select network option allows me to see all the available network and often the Strengths do not match others as if my phone is inaccurate and even if it shows up it doesn't seem to keep connected or connect at all. The speeds are slower and it does not seem to work like other US phones do. I have a few beliefs that could be true. I believe that there are other technologies used in Europe and Russia that the phone has built in because it is not typically on American Networks and that it is causing issues connecting/staying connected. I also believe that the way that the phone switched from one tower to the next is also different(and not working) so if I move out of range of 1 tower that the connection does not reset to the next tower but just disconnects. I have not been able to use adb to debug and read the logs and try and see if there are errors that the phone does not tell me. Although I have seen other discussions showing similar issues with certain parts of my issue but mine seems to cover a broad list of issues.
