Venue 7130 Pro 4G Modem issues

Hi,

I bought a used Venue 7130 Pro Tablet with keyboard. As I see after I remove the back cover, this device has 4G / LTE modem, at least I can put in micro SIM card near the battery. But if I check the "Network adapters" I don't find 4G/ LTE mobile broadband card, only Wifi card. What should be the problem? Maybe can I download another card driver?
