Alternative options

Buying a cheap, unlocked prepaid phone to use when traveling abroad is often much more cost-effective than using your normal plan abroad. Then you can buy a prepaid SIM in your destination country and simply pop it into your phone for access to the local network. You can call your carrier and ask whether your phone is compatible with international SIM cards.
