If someone calls me using an iPhone app, will it cost me any extra money?

My friends been calling me using an iPhone app. She is not long distance, we used to talk all the time and her phone has just been turned off (her reasoning for using the app). Will it cost me any extra money for her to do that? Its a free app.

Not at all. Unless its an international number or something lol

  • Will using my iPhone's hotspot cost extra money? I have an iPhone 4s (which is up to date on all IOS updates) and I have the unlimited data plan at AT&T. I'm leaving for a road trip tomorrow, and I wanted to turn the hotspot on so I could use that Wi-Fi on my laptop during the trip so I won't get bored. It says I need to set up an account for it, which I will do later… But would any extra charges be added to my bill?
  • Will it cost me extra to text someone in the US? I've been talking to someone from the US an we both have iPhones, but I don't know if it's gonna cost extra for me to text her and I'm with t-mobile. Will it be the same as iMessaging (free or whatever) or is my phone bill gonna give me a heart attack?
  • Using my Spring iPhone in another City? Any Extra Charges? I live in Los Angeles and I'm going to be visiting New York soon so I was wondering if using the Internet, texting or calling would result in extra charges on my cell phone bill?
  • If I text someone out of country for iMessage with an email will it still cost money? If I text a girl from the UK off of her email for iMessage instead of number, would it still cost more money? I have iphone 5s AT&T unlimited text, but if I use someone's email for iMessage instead of number that doesn't live in the US, will it still cost more money
