Alternative options

Buying a cheap prepaid phone when you get off the plane can often be much more cost-effective than using your usual plan abroad. Or, you can call your carrier and ask whether your phone is compatible with international SIM cards. If so, you can buy a prepaid SIM in your destination country and simply pop it into your phone for access to the local network.


We evaluated all the major international roaming cell phone plans on the market, including those offered by AT&T, Google’s Project Fi, MetroPCS, Sprint, T-Mobile and Verizon Wireless.

To determine the best plans, we looked at the price of the international roaming option before taxes and fees, the price per gigabyte of data, and the price of international calls and texts.
