Occasionally, my iPhone 12 mini sometimes says cellular, zero or four bars, signal strength, but sometimes it would say cellular, no signal. So what does it mean when it says zero of four bars? On phones with home buttons, The correct announcement is no service, but still, it sometimes displays the carrier name and says zero of four bars, also, when it says zero of four bars, there is a cellular service icon, which can either be announced as 5G, LTE, 4G, 3G, GPRS, E, and one X. When it says no signal, no network name appears and older iPhones Without home button will say no service.

It might be your carrier…
It might be your carrier having issues on their end. Or maybe they are doing maintenance. Try restarting your iPhone and see if that fixes the problem.
