ABSTRACT The present invention relates to a device (10) for rendering services such as for example telephone communication, data communication and so on comprising a terminal unit (1) and an access unit (2), the terminal unit (1) comprising terminal unit identification means (PIN1) which are stored in the terminal unit and the access unit comprising first access identification means (IMSI) in the form of a code or similar, terminal unit (1) as well as an access unit (2) being lockable. In the terminal unit are furthermore first access identification means for a given number of access units (SIM) stored wherein upon starting up of the device involving contact between terminal unit (1) and actual access unit (SIM) (2) with a certain access unit identification means (IMSIc), the code of the identification means (IMSIc) of the access unit (2) is compared to in the terminal unit (1) stored code/-s for first access iclentification means (IMSI3) in the terminal unit, correspondence between stored access identification means (IMSI,) and actual access unit identification means (IMSIc) leading to locking up of the terminal unit whereas non-correspondence between stored and actual access unit identification means (IMSI2 ?
