Are there any free iphone calling, texting apps?

I know there are ones like viber and whatsapp, but i mean is there one that:
a) doesn't require internet- if not fine.
b) doesn't require the other person to have the same app- sends the message straight to their sms inbox?

I use one called Magic Jack. It works just like any phone. You need Wi-Fi at least.

Not that i knowof try skype though

  • My iphone is calling and texting people whilst I sleep Woke up this morning to find a missed call from my mum, and a text asking why I'd called her, with a reply from me saying that I couldn't talk and would call her later. I know that this is one of the auto texts but I don't know why it would have sent it if I haven't clicked auto reply. I also have no idea how it phoned my mum with no assistance from me. Is this a technical problem or have I been sleep calling? Haha thanks for any answers
  • My iPhone 4. Calling/texting not working? I bought this iPhone yesterday of my friend at school. Internet Facebook etcworks all good, but it's just calling and texting. When I goto call someone, it says your handset has been blocked on this network. IT ISN't STOLEN.
  • Is there any calling apps that work without Wi-Fi? I have a 5 Generation iPod. My parents can't afford an iPhone for me, and I can't afford one either. I want to call and text without Wi-Fi on my iPod. Is there any LEGIT and REAL apps that do this? If you don't have anything nice to say, don't say it at all. -Thank you.
  • Is texting or calling from iPhone to iPhone free if you're in a different country? I live in the US And I'm going to Sydney, Australia for 3 weeks in a little while but I'll only be 17 when I go with one of my friends and I wanted to make sure I could communicate with my mom. There aren't many hotels I can find with free Wi-Fi or even Wi-Fi in general. The hotel we're probably going to stay in only offers wired. Both my mom and I have iPhone's so if we text or call on the cell phone data (I have Verizon) will my phone bill price be crazy high?
