I have a latest 4G SIM card bought and I am searching for a suitable 4G LTE supported new handset, preferably, an Android phone. I am watching all those HTC One M10 (now called as HTC 10) rumors. I want to buy this phone. Is it a 4G LTE phone or just a 3G phone? I want it to be the future proof, as the 5G network could come soon. Does 5G also supported by HTC 10?
