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 before arriving at today's eSIMs. Apple first supported this technology in 2018 with the iPhone XS and XR, but only recently fully embraced its advantages.Market Impact
Global adoption of eSIMs could put pressure on carriers to upgrade their infrastructure. This shift may accelerate innovation in mobile services, with potential reductions in operating costs and greater flexibility for consumers.Limitations & Challenges
Although eSIMs offer many benefits, not every country is ready for this transition. In China, for example, government restrictions require in-person identity checks, complicating eSIM adoption. Additionally, some carriers still do not support this technology.FAQ
