If you have your Sprint number setup as your Google Voice number, you can make international calls at very low rates with Google Voice. Rates are determined by Google and calls are routed through Google Voice. You will be billed for these calls by Google Voice, not by Sprint.
Get started by purchasing credit through Google Checkout. Rates vary by country and will be counted on a per minute basis. To view international calling rates, simply click the See Rates link in the Billing tab of your Google Voice Settings page.
To make an international call from your Sprint phone on Google Voice, simply dial an international call as normal—enter 011, the country code, and then the number (for example: 011442012345612345).
