Until the advent of smartphones and a App Stores users depended on mobile phone subscriptions to be able to call someone or send an SMS, but in recent years things have changed a lot. At the moment, any device that has an internet connection can give users the ability to talk on the phone or send text messages without having an active data plan for their smartphone. Of course, this kind of application must also exist on the interlocutor's smartphone, but they can prove to be a real alternative for anyone who wants to partially reduce the costs of a subscription.
Applications such as FaceTime, Viber, Skype, WhatsAppMessenger or Tango offers you the possibility to make calls VoIP video or voice, some even allow you to send text messages, and where others fail to satisfy you, the service intervenes iMessage which allows you to send text messages, videos or pictures to any other iDevice that has it active. If you are roaming, then one of these applications can be combined with an internet subscription and can considerably reduce the costs of calls or messages, but it all depends on the people you are talking to and how interested you are in using them.
Of course there are many similar applications in the App Store, but the 5 below plus FaceTime and iMessage are the most popular and having them installed you have the best chance of finding a friend with them available.
