Introduction Features of the SIM Card, eSIM and iSIM.
Features of the SIM Card, eSIM and iSIM compared. There are now different types of SIMs on the market so let’s compare the differences and see why it is important for your Mobile Brand.
While traditional SIM cards offer familiarity, eSIMs and iSIMs provide enhanced flexibility, security, and convenience for both MVNOs and subscribers. eSIMs, with their remote management capabilities, are widely adopted and offer a balance between compatibility and modern features. iSIMs, although currently less common, provide robust security and are particularly suited for specialized and compact devices. For the history details see here.
The choice between (or all) these technologies depends on your MVNO’s target market, device compatibility, security requirements, and long-term business strategy.
