A method for accessing a smart card (SIM) from a host device (TE), the smart card being connected to the host device (TE) via a telecommunications card (MT), the telecommunications card (MT) comprising a command interpreter (TA) for interpreting host device commands and a modem (ME) with associated smart card reader for enabling said telecommunication and user identification, the modem (ME) being only accessible to the host device via the command interpreter (TA), the method comprising the steps of: (a) providing an access command (AT+CSIM) on the host device, said access command instructing the command interpreter (TA) to pass on any attached command originating from the host device (TE) to the smart card reader; (b) attaching an application command (APDU) to said access command (AT+CSIM) and forwarding both to the command interpreter (TA); (c) performing said application command (APDU) on the smart card reader; (d) storing a response given by the smart card (SIM) to said application command in a first buffer which is accessible towards the host device (TE).
