How does 4G and LTE work in a tablet without a SIM card?

Question

Mobile Internet

Need a tablet for windows. I took a closer look at Microsoft Surface 3 64GB LTE , this tablet claims to support 4G and LTE, but there is no 3G support and there is no SIM card slot. Apparently, at some points I am behind the times, but as far as I know, mobile Internet is provided either by opsos or iota. But if there is no SIM card, how is the connection to communication services and how are they provided?

Answer 1

And where did you get that there is no slot for a SIM card?

All Surface 3 tablet models will be equipped with nano-SIM SIM card readers

Also lte support in fact means 3g / edge support, it's just that no one writes about it.
