Historical Context
SIM cards have evolved significantly since their early days. From a credit card-sized format, they went through mini, micro and nano SIMs until reaching today's eSIMs. Apple began supporting this technology in 2018 with the iPhone XS and XR, but only recently fully took advantage of its benefits.Market Impact
Global adoption of eSIMs could pressure operators to update their infrastructure. This change could accelerate innovation in mobile services, with potential reductions in operational costs and greater flexibility for consumers.Limitations & Challenges
Although eSIMs offer many benefits, not all countries are prepared for this transition. In China, for example, government restrictions require in-person identity checks, complicating eSIM adoption. Furthermore, some operators do not yet support this technology.FAQ
