Passport international plan
With the Passport plan, I understand the overseas person can send unlimited texts. Presently, I have an AT&T unlimited wireless package and I have questions how the Passport plan works as it pertains to the phones within the plan.
What happens when the person/phone overseas receive texts (from someone in the U.S) - are they charged anything?
For the person in the U.S., are they charged anything for sending a text to the person that is overseas? And vice versa, are they charged for receiving a text from the overseas person?
Is it necessary to have the Passport App? What’s the functionality or purpose of the app? What’s the difference between using a 'participating' wi-fi hotspot and a ‘non-participating’ hot spot?
