Yes, cellphones are extremely handy inventions, but you want to supplement them with a phone card, especially if you are driving in areas that offer limited cell signals. Having a reliable prepaid phone card in your travel arsenal will be invaluable when you are traveling. Trust me on this one.
Phone cards are used by many people nowadays extensively. Therichcom.com is a website which provides cheap and effective calling cards. Compared to calling your home from hotel telephone lines, the rates are very inexpensive. I have a cousin who moved to England last year, and I always use a phone card to call her. I have compared prices on many cards and sites, and this site has the cheapest rates. Their rates are much cheaper than calling from my home phone even.
Something I was very surprised about is the fact that the quality of sound is excellent. I had absolutely no interference or noise and the clarity was great.
