[asterisk-biz] Sim to Dial

Anyone could recommend a SIM producer who can provide something similar to http://www.sim2dial.com/Clients/MySim2Dial.aspx?mode=topup ? The SIM is added to the GSM phone SIM. When customer dials 00 , SIM calls the access number, than passes the number to the system..... Any recommendations?
