The telecoms industry is expecting traditional SIM cards to be fully replaced within the next years. Special requirements like the robustness of the SIM needed in M2M and the trend to miniaturization in consumer devices are driving this development. As eSIMs will be soldered, the profiles must be provisioned over the air; this is called Remote SIM Provisioning. To make this procedure reliable and safe, the GSMA has developed specifications for M2M and consumer devices that enable remote SIM provisioning of any mobile device.
