<p>An apparatus, and corresponding method, for verifying the procedure to access mobile telephony networks through SIM cards provides that said cards are stably placed in a single central electronic unit which, upon verification requests carried on by various phone service suppliers from remote terminals, is apt to read the parameters of the peripheral devices placed at the mobile telephony network area locations that are requested to be tested; in this way said devices act, in the various tests, as mobile telephones containing the specific SIM cards involved in the verifications. Data relating to verifications as well as said parameters are transmitted between peripheral devices and central electronic unit through dedicated digital transmission lines or through the telephony network itself.</p> |
