摘要 |
The present invention relates to a system and method for providing prepaid telecommunication services. More particularly, prepaid telephone calls can be made by users without entering any access code, if such calls are made from telephone numbers previously registered in the telecommunication system in connection with valid access codes. Prepaid telephone calls can also be made from non-registered telephone numbers after providing the telecommunication system with a valid access code.
