I am always very careful not to send sms unless the receiver has an iphone
and I am also careful to verify that the message turns blue (iMessage) and not green (sms)
However, I have just received a bill of 57 text messages to/from international, which is approximately the
number of iMessages I have sent.
iMessages are free and only use data, so is this happening to anybody else?
What gives?
