What is a SIM card? SIM card, also known as a Subscriber Identity Module, is a small circuit board that allows your mobile device to communicate with your carrier. SIM cards contain a unique serial number (ICCID) and international mobile security identity number (IMSI) that tell your carrier your device is allowed to operate on its network. When you upgrade to a new device, you can transfer your old SIM card as long it is compatible with your new phone.
SIM cards come in three different sizes (Standard SIM, Micro SIM and Nano SIM), and the type you’ll need will depend on the device you purchased.
Standard SIM cards are generally used in devices made prior to 2010. It is the largest of the three SIMs types, measuring 25x15mm.
Micro SIM cards were introduced in 2010 and still appear in some devices. They are slimmer, smaller and lighter and measure 15x12mm.
Most newer smartphones, including Alcatel devices, now use Nano SIM cards, which were first introduced in 2012. They are the smallest SIM card and measure 12.3x8.8mm
