Certain modems work, some doesn't. 3G/4G support is handled by Android, which is meant to be phone operating system for fixed hardware in first place, therefore it can't support all the 3G/4G dongles someone stamps somewhere in China. Android isn't Windows with its ample hardware support. You just can't buy some cheapest dongle and hope it works, you have to first check what dongles are known to be compatible!
