How to make a call from Los Angeles airport?

I tried to find duplicates for this question, but was unable to find any.
I am travelling from India to Los Angeles for a short visit. In case of any emergency, if I want to make a call (from my mobile phone, without having to access internet) to my relatives in the US, immediately after landing, from the airport, is there any way to do this?
PS: During my last visit I tried to connect to WiFi from Los Angeles airport and then tried to text my relatives. But due to unknown reasons I was unable to connect to the airport WiFi. I am trying to avoid that situation, this time by having an option to make a call, if required.
