The speed of an eSIM and a physical SIM card is not determined by the type of SIM, but rather by the network and the device. The speed of the network depends on various factors such as network coverage, network congestion, and the carrier's network infrastructure. The speed of the device depends on the hardware specifications, such as the processor and modem, as well as the software and network configuration.
In general, both eSIMs and physical SIM cards can support fast network speeds, such as 5G or 4G LTE, as long as the device and the network are both capable of supporting those speeds. However, actual speeds may vary based on various factors, and may not always reach the theoretical maximum speeds.
It is also worth noting that some devices may be optimized for use with eSIMs, which can provide a more seamless and integrated experience, but this does not necessarily result in faster network speeds. Ultimately, the speed of the network and the device are more important in determining the overall performance.
