FIELD: communication facilities.

SUBSTANCE: invention concerns mobile communications. Claimed method involves reception of data including at least equipment (CB) ID (IMEISV) and security module (SIM) ID (IMSI), by control server (CSE) over network (NET); analysis and check of the data by control server (CSE); generation of cryptogram (CRY) including checksum (FIN 1) of application (APP), equipment (CB) and security module (SIM) ID data and commands (INS RES) for the security module; the cryptogram (CRY) is transferred over the network (NET) and equipment (CB) to security module (SIM); application (APP) is checked by comparison of checksum (FIN1) retrieved from obtained cryptogram (CRY) with checksum (FIN2) defined by security module. During initiation and/or activation of application (APP) security module (SIM) performs commands (INS-RES) retrieved from cryptogram (CRY) and, respectively, provides or blocks access to certain resources (RES) of security module (SIM) depending on the result of the check performed earlier in respect of that application (APP).

EFFECT: eliminated possibility of improper use of applications in mobile devices.
