iMessage Settings for travel
I understand that iMessage is best used with a WIFI connection during international travel, but what if I want to use iMessage in a limited capacity when wifi is not available? Will iMessage work if I have cellular data turned ON, but have data roaming turned OFF? Or do I need data roaming on as well? I plan on just sending quick short texts to my travel companions, will save the picture sends until we have wifi but want to use iMessage on occasion when we are walking the streets in India!
thanks
iPhone 6, iOS 9.2, iMessage
