going to Ireland and do not want to buy international package

[AC Question]

can I just turn off data and use wifi and not incure any charges from provider?

Yes. However, I'd suggest disabling the roaming option and keep data off. Will you be purchasing a separate calling plan (voice no data)? If not, then I suggest enabling airplane mode. WiFi should still work if you enable airplane mode and this will prevent calls from being made accidentally.

You can put your phone in airplane mode and use Wi-Fi for messaging and even calling. Check out our new app iPlum. You can get free messaging and calling when your friends also use iPlum. If you need more flexibility, simply get a U.S. phone number on iPlum and then you can reach any mobile phone or landline in the U.S.
