simple introduce of the dialer
our auto dialer can work where there is pre-paid telephone and pre-paid card.
Our auto dialer has good security protection which could help carriers and IP card vendors to bind their card (access number, card number, PIN etc) with auto dialer, without knowing the password, user could not modify it. So user will come to you again when they need to buy more minutes from you.
