“Roam” online for international calls
If you have an Internet-accessible device, like an iPhone, iPod
Touch, or Nokia smart phone, you can create an account with Truphone (truphone.com).
Download the free Wi-Fi software and make international calls for as
little as 2 cents a minute. Alternatively, a few companies sell
dedicated Wi-Fi phones for $100–$200.
Pros: Wi-Fi calls are inexpensive or free; you don’t have to change anything about your phone or your plan.
Cons: To avoid additional charges, you must be in a Wi-Fi hot spot.
