does the sim card control both 4g & 3g? my download speeds are decent but when on 4g i often loose data or 4g becomes unresponsive until i reboot or restart the connection. this happens on all the radios. could it be a bad sim or perhaps the 4g in my area is not reliable?

would verizon send me a new sim or will i have to unroot to take it into a store?
