calling all techno wizards!
can't for the life of me remember if i could text while in aruba last year

i have verizon with int'l activated
my questions are:
1) texting between aruba & the us - can i? and how badly will it put me in the poor house

2) texting with others on aruba - i'll be there in may for a wedding & will need to text like mad to coordinate meet-ups, etc.
any insight would be greatly appreciated
