Showing Signal Bars Without Inserting The Simcard!

[JazzieJaz]

Hi friends.
I'm a newbie in this forum. Just got a new Samsung galaxy tab s3, and there is a full signal bar on my status bar above the page; just like when you insert a sim card and that shows the strength of your signal. The question is,

why can i see a full signal bar on top whereas i haven't inserted a sim card!?

I'd really appreciate it if you'd answer.

That is basically normal.

The radio is still there and on, even without a SIM.

If it is annoying, you could go to settings set airplane mode, then go to WiFi and turn WiFi on.

AFAIR that will take the signal meter off the top bar. (I am Not 100% sure and my spare phone (WiFi only is at home today)
