The present invention discloses methods and systems for transferring SIM card information from a first device to a server. A first SIM card is housed in the first device or in a first modem connected to the first device. When the first device boots up, it identifies the first SIM card and retrieves SIM card information from the first SIM card. The first device then sends authentication information to the first server and requests historical SIM card activity information. Historical SIM card activity information received from the first server is stored in a storage medium, and is used for determining whether to use the first SIM card. The first server performs steps of receiving a first request message from the first device, and determining the SIM card identity specified in the first request message if the first request message is authentic. The first server retrieves and sends historical SIM card activity information of the first SIM card to the first device.
