Hi,
I got the 3-day Easy Roam Perk INTL. During a trip to Dominican Republic, I used my phone within those 3 24hr period but was charged $18 for using my phone on my last day.
According to my bill, I used my phone
Day 1- Jan 21st 07:07PM
Day2- Jan 22nd 12:35PM
Day 3- Jan 23rd 12:33PM
Day 4 ($18 charge)- Jan 28th 08:45 AM
However, I am pretty sure the 24hr period starting the 27th at 12:33PM should end the 23rd at 12:33PM… The call made at 08:45 AM was almost 4hrs before the end of that 24hr window on my third day.
