Difficulty: Moderately Easy
Step1
If you travel frequently, spend the extra per month to get a nationwide plan. One phone call could easily rack up ten times that much, so it's a good investment.
Step2
Know your network and home coverage area. Most companies have maps indicating what areas are in your network, out of your network or have no coverage at all. Although these maps are not exact (you still need to pay attention to the indicators on your phone), they can give you a rough estimate of what to expect.
Step3
Update your preferred roaming list (PRL). This will give you the most current information about the roaming indicator on your phone. Update your PRL every 3 months.
Step4
Set your phone to warn you if you are going to make a call that would incur roaming charges. If you are about to participate in a call that will incur roaming charges, the phone makes you press a button, such as "1" or "ok," before making or answering the call. Most phones will allow you to do this. Look for "Call Guard" or something similar in the Settings menu.
Step5
Set your phone to ask for confirmation before downloading messages when you travel. This practice will keep you from getting text, pix and flix messages while you are on a roaming network. This is also usually in the Settings menu, under "Message Settings." It might be called "Message Retrieval Options" or "Automatic Retrieval Settings."
Step6
Purchase an international SIM card for travel abroad. These allow you to get better rates while out of the country (in many countries, it allows you to receive incoming calls for free). These can be purchased from companies like Cellular Abroad or Telestial (see Resources below).
