How to Reduce Cell Bills With Prepaid SIM Cards

Save on cell-phone calls to the U.S.

If you travel internationally, phone charges back to the U.S. can add up quickly. One smart solution is to buy a prepaid SIM card that is specifically discounted for international calls, then reload it with minutes when needed. For example the United Mobile card (united-mobile.com) works in GSM handsets in 140 countries; Europe-to-U.S. calls are €.29 per minute, and incoming calls are free in 80 countries.
