Sorry your miss understanding my point
I am not debating pro's and cons of messaging services on different devices just noting outside mainly US and AUS sms/mms is a dying trend
Many like to think that sms/mms unlimited is free but in truth its just a bundled in with courier charges for data etc etc as it's conditional
That's why particularly in US the carriers like Iphones as you pay by stealth for sms/mms but because of the popularity of Imessage it's barley used
Many in the world have smartphones with no data packages and rely on wifi alone or pay $2-5 a month for say 10GB and never use sms/mms as it's chargeable
Habits in US on sms/mms are not followed in many other countries
and millions work on entirely different budgets for their phone usage
