If I got it right, tablets do not have sim cards but get internet through wifi.

The other day I was with someone who had a tablet, I believe it was a Samsung. And I noticed that it had a 4g LTE reception icon. What does that mean? How does it get 4g without a sim card?
 
Solution
If it can connect to a 4G signal, you must have a data plan to go with it. It works the same as most smart phones when it comes to sending and receiving data.
