Iphone 4s don't work when it has no Wi-Fi?

Ok so i got my phobe back after a year of punishment, my parents switched out my sims card, and when i go to places without Wi-Fi, it doesn't show anything, like 4g, LTE, none of that. Is it because my cellular data is turned on?
it use to work without Wi-Fi, please help?

It would likely be because your cellular data is turned off, not on.
