Tuyo is the latest phone service created of IDT. This phone service is for the Latin America area and all calls being made to and from Latin America. Tuyo is different than most phone card companies because they offer cell phones you can buy to use the phone cards with. If you buy a cell phone with your phone card, your rates are lower than most phone card prices but the trick is you have to buy a cell phone. If you wish to buy a phone card from Tuyo without buying the phone, your rates are subject to change and they are allowed to add any extra charges as they please. They claim these rates offered for the Tuyo network only. So why go through the hassle of spending extra money to buy their cell phone to receive the lower rates. Why not save yourself some money and buy a phone card from Pingo. Pingo does not require their users to buy a cell phone to receive low prices and the prices you see on their website are the prices you pay. So sign up with Pingo and save yourself the time, stress and money. Pingo, the last phone card you'll ever need!!
