Do you have an iPhone that won't make calls and just shows the SOS logo (or No Service on older iPhones) at the top of the screen? You aren't alone, and it seems that there are plenty of people suffering from the same issue. The good news? It isn't your fault and your iPhone is working as intended.
The bad news? There's a huge outage ongoing that is affecting some of the biggest carriers in the United States and there is no telling when it will be fixed. There's nothing for you to do but wait, which might not be the news that you wanted to hear.
