Best way to call the US from Europe?

For everyday calls the best is to download a computer program called skype on both your and her computer you can talk all you want for free. For emergencies when she gets over there have her purchase an international cell phone. It is not worth getting an international cellphone over here. If an emergency happens from over there and she needs to get ahold of you before she purchases a intl phone get an international calling card from your current cell phone provider that she can use on her cell she currently has. Aslo make sure she has an ISIC card and the website gives great travel advice and tips. the website is www.istc.org

just use the internet for everyday contact, cheaper than using international calls. but for everything else, you need the country code or w/e its called and replace the first 0 with it. for example, the UK one is 44, so to call the UK number 0159 494 484 (random number) itd be 44159 494 484 from anywhere else in the world.

well she get get something called roaming on her cell phone in that way she wil be able ot use her cell phone everywhere she want but it will be expensive very expensive she can purchase a phone car and call u when she will need to or download skype she will have to pay i think 10 euro per month
