Mobile phone roaming charges can be very expensive when I want to call home while abroad. So, in order to save expenses on mobile phone bill, I am using phone card as a cheaper option to call home. Before going abroad, I will usually try to find phone cards available in the country where I am going to visit. Website like PhoneCardsAvenue will help me to compare, find the cheapest rate and buy phone card online. I am not sure about other phone card company but PhoneCardsAvenue do have great offers like cheap calling rates and 3% cash back rebate program. The rebate program will give me 3% saving whenever I purchase phone card from them.
In term of savings, I have saved a lot of money by using phone card. Maybe, I can buy a new iPhone soon with the savings.
