The invention creates a mobile station comprising a mobile end device (ME) with a secured runtime environment (TEE) and a removable or firmly implemented security element (SE), with an end device send server (TEE-TSM) arranged in the security element (SE), which is arranged to send to the secured runtime environment (TEE) end device messages which can be received by the secured runtime environment (TEE). The end device messages are sent by a trusted service manager (SE-TSM), which is provided for the security element (SE), to the security element (SE), thereby higher efficiency being guaranteed at maintained security.
