Make cheap international calls from your mobile phone
1) You give us the phone number of a friend in another
country, and we give you a local number for them.
2) Save this number on your mobile so you can call
your friend whenever you want, for a fraction of your
normal international rate.
“... there are a handful of services available that allow you to make cheap and sometimes even free international mobile-to-mobile phone calls. Rebtel is one of those services, and trust me, you'll be glad you found it.”
