2. Secondly, CTT's mobile phone business is either aimed at local calls or long-distance calls, and no business is aimed at both local calls and long-distance calls. Tietong charges 0. 15 yuan/minute for local calls, regardless of long distance and local calls, and there is no monthly rent, but it only cares about the caller, regardless of the called party, and it is a callback card. You need to enter the card number and password when using it, which is not suitable for business people or people in a hurry. Tietong's long-distance services mainly include 1799 1 and 17996, and the charges are 0.30 yuan/minute+local telephone charges. Sometimes CTT will deposit 100 and send 50- 100, but no matter how much discount, when you make a long-distance call, the long-distance fee will be deducted from CTT.
