Your mobile phone contains a small, removable electronic chip used to keep data that is unique to both the subscriber and the operator: the SIM card (SIM stands for Subscriber Identity Module). Mobile phone operators like Videotron, and especially those with GSM, LTE or UMTS networks, offer their own SIM cards to subscribers. This card contains information that makes it possible to identify you as a user, and your mobile phone, on the mobile network. Among other information, the SIM card securely stores the following:
  • Your mobile phone number;
  • Information related to your mobile plan;
  • Information that belongs to the subscriber, such as contacts;
  • Your operator ID;
  • Localization and security data;
  • Certain operator-related mobile applications.
All SIM cards can store a maximum of 250 contacts. When you enter a new contact in your phone, your device will usually ask whether it should be saved on the phone or on the SIM card. The latter is a good idea, since it will make it possible in most cases to easily transfer your contacts if you change your phone. There are different SIM card sizes: the standard SIM, the mini SIM, the micro SIM, and the Nano SIM, which dimensions are smaller and smaller. The card contains a chip that features both an integrated circuit as well as some memory, usually between 32 and 128 KB. Many companies are now developing new features that will be stored directly on the SIM card, which would result in increased security, for instance in the case of monetary transactions. Who knows maybe your smartphone will soon become even smarter because of that little chip! Click here to view the list of Videotron devices and their associated SIM card types.
