Hi, What does it really mean by smartphone has 3G support or 4G support? What makes the difference in terms of compatible to 3G or 4G in smartphones? Is there any specific hardware system is used in mobile by which we can say it supports 4G or its supports only 3G?
 


Yes the hardware in the phone is what determines if it can connect to 3G or 4G. If you are asking for what specific hardware does it, here is a recent article about 5G hardware that has some info http://www.tomsguide.com/us/qualcomm-x50-5g-modem,news-23678.html
