These will only be free (abroad) over wifi and only to other people with iMessage. IMessage is built right in to the messaging app so there is nothing you need to do to activate this feature. There are many apps out there that let you text for free but the iPhone allows you to send unlimited texts over wifi for free using iMessage. The key is to be flexible and to realize you may not always have access to texting, calling, and the internet at all times when traveling but you can get them all for free. This requires no jailbreaking or unlocking iPhones. Luckily there are ways to use your iPhone abroad for free. However, data roaming fees, excessive charges for texts and calls can lead to many people turning off their phone and leaving in in the room. Today we go everywhere with our phones and traveling without them is not an option.
