All devices uses a SIM card to connect to the mobile network. There are four different sizes: Standard SIM (1FF), Mini SIM (2FF), Micro SIM (3FF) and Nano SIM (4FF). The right size of SIM card to fit in your device will depend on the manufacturer. At Cobira we deliver SIM cards that are perforated so you get 3 SIM card sizes (Mini, Micro and Nano) combined, to fit every device model. We are also able to deliver your SIM card as eSIM. An eSIM is a SIM Card that is downloaded and embedded in your device and lets you use the network in the same way as a traditional SIM Card.
