International Cell Phone Plans
When looking for international cell phone plans, the best thing to do is to check out the phone to make sure that it can use both CDMA and GSM technologies. This is easily done on the company of choice's website by selecting the option for 'international phones' or by asking a salesman in a local retail store which phones allow for both frequencies.
Verizon and Sprint both use CDMA, while AT&T and T-Mobile use GSM. Depending on the frequency in which you travel, choosing either AT&T or T-Mobile may work better than Verizon or Sprint.
Customers and reviewers have stated that T-Mobile by far has the best GSM network, as well as reasonable prices for international cell phone plans. The company offers a $10/month international talk and text plan that can be added to any existing one (if already a T-Mobile customer); for example, if you are using their unlimited plan at $99.99/month, the added ten dollars now allows for unlimited international talk and texting.
The main website also has a listing of international cell phones, such as the Samsung Galaxy T featured on the right.
On the other side, Verizon has the more expensive plans, though they do offer a global phone program for any traveler staying abroad for less than 21 days. Many of their BlackBerry and Motorola Droid offerings are available for overseas use. Data plans for Verizon international start at $30/month for only 75MB while in Canada or Mexico and only 25MB while in Europe.
