INternational WiFi calling
I have an iphone 6. I am going to Italy and was planning to bring a device that provides a portable wifi hotspot. The hotspot provider will give me free calls to anyone who also has their app. But will charge 10 cents a minute for any other international calls. So I will have wifi wherever I go. I have some confusion and some questions:
1) If I do not buy the AT&T International plan, what does that mean if I make phone calls or send texts to other AT&T phones that are in my plan, but also in Italy with me?
2) What does that mean to making phone calls to the US? Do I trigger my AT&T phone orhave to pa long distance rates if I am using their wifi?
3) If I do sign up for the AT&T International plan, can I use my iphone 6 as a hotspot for a computer or do I still have to have a wifi signal from somewhere? What I am asking is, do I have to have both the International plan and a wifi hospot or is it overkill. Help - I am not a technical savant! Thanks so much for your help
