Aussie girl going to Europe for 6 months. Can I get a sim for use in my Aussie bought iPhone 4? What is my best option?
You need to make sure your iPhone is unlocked. If it is, then you can use it with a sim anywhere in the world. I think Aussie uses gsm network and so does Europe. If you bought your phone through a cell phone provider like Vodafone, etc. then check with them if it is unlocked. Often when you buy from the cell companies, the phone is locked to their network only. about 6 years ago

The iPadNomads are right - make sure you're phone is unlocked before you go and then all of this will be easy! about 6 years ago
