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.
Only happens in areas that have poor signal
Thanks for the suggestion, after I restarted my iPhone, it says cellular, one of four bars, signal strength instead of 0 of 4 bars, it seems that this VoiceOver bug has been around since iOS 13, visually, the bars are not filled, none of them are filled and VoiceOver says zero of four bars, but on iOS 12 or below, it would say no signal, but I believe the reason why Apple changed it to zero of four bars is because for the phones with no home button, no service has been replaced with no signal, and Apple probably have decided that zero of four bars is a replacement to no signal when all the bars are blank.
