Data use- texting and calling on iPhone 4s?

When I text/ call on my iPhone and I don't have Wi-Fi, is it using up data?
And what takes up data?

Anytime you are using your apps that uses data internet from your cell phone. Texting uses your phone number and it comes from your text messaging plan. However if you use a texting app such as Viber, Textfree then it uses data internet and not use your text messaging plan.

If you are in a Wi-Fi area then you can switch to Wi-Fi (change your setting) and turn off your data internet plan on your cell phone this way you don't use your data internet plan. You have unlimited Wi-Fi if you are in a Wi-Fi public hotspot (McDonalds, Starbucks etc) or through your home network Wi-Fi. Your iphone apps and internet also work in Wi-Fi as well

If you don't have Wi-Fi then the phone will always use the data internet plan for apps, and internet.

  • Will data be charged for texting and calling outside the country to another iphone? My girlfriend is going to costa rica for the summer and i need to know will me calling and texting her use up my date. It would be facetime audio and imessage only. Also i have att if that matters.
  • Person keeps calling and texting me? So today this random number started calling me and texting me saying some crap. I have a jailbroken iphone so i started text bombing him and then he starts saying he is going to come to my house and fight me and i also posted his number on face book. He knows me some how or atleast knows someone thats knows me cos he got my number and he knows my name and where i live. I have no idea who it is but he is being a dick to me so what would you recommend i do?
  • 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 data, calling, and texting all stopped working on my iPhone? My carrier is Verizon, and all of the sudden my data and calls and texts all don't work on my iPhone SE. I woke up one morning and nothing worked so I updated my phone thinking maybe that was it but all that did was enable iMessage and FaceTime through my e-mail… I know my Verizon is still working though because nobody else in my family is having these problems. It's really stressing me out and I don't know what's wrong.
