Unlocking a phone
Using a European SIM card
International roaming with a U.S. carrier

Content: The best deal varies depending on the countries you plan to visit and the length of your trip, but here's an example of one European package: Orange, a major French carrier, sells a SIM package for EUR 39 ($46) that includes the following: A SIM card with a French phone number
120 minutes of phone calls, good anywhere in Europe
1,000 text messages, valid anywhere in Europe
1GB of data transfer, throughout Europe
It's easy to refill the package online, as well, should you max out your data or phone minutes. But keep an eye on these cellphone carriers' policies – some require you to bring in your original passport in order to qualify for the purchase of a SIM package, for example. GSM vs. CDMA phones
Still, there's a catch: European SIM cards are often accepted only in GSM phones, though some newer CDMA phones are starting to support them, as well. GSM and CDMA are two different types of network technology. European mobile carriers all use GSM (which requires a SIM card), as do AT&T and T-Mobile in the United States. Verizon and Sprint, on the other hand, use CDMA, so phones bought through those carriers might not use SIM cards. All iPhones use GSM technology, except for a CDMA version of the iPhone 4 manufactured specifically for Verizon and Sprint.
