I don't know if it is my particular plan or what, but I only turn off cellular data. I still receive phone calls - spam goes straight to voice mail with no charge. If I answer from my kids it charges $1.79 per minute for phone calls. Texts are $.05 to receive .$.50 to send. No $10 day pass triggered.

What Kim is saying above is exactly what happens for me.


Edited to add: When I am at the condo - I use wifi and we FaceTime and iMessage at no charge. But I talked for a a bit with my daughter who was going through a divorce last year with no wifi and the only charges were $1.79 per minute, which still ends up cheaper than $10 per day.
