A Data eSim is an embedded SIM card that is designed to provide data connectivity to devices that have cellular capabilities, such as smartphones, tablets, laptops, and IoT devices. Unlike traditional physical SIM cards, Data eSIMs are embedded into the device and cannot be removed or replaced.

Data eSIMs allow users to connect to mobile networks and access the internet without having to physically swap SIM cards or sign up for a separate data plan. Instead, users can purchase and activate a data plan on the eSIM from a mobile service provider of their choice.

Data eSIMs are particularly useful for travelers who want to avoid high roaming charges when traveling abroad. They can purchase a local data plan on the eSIM of their device, which allows them to connect to the internet using local mobile networks, without having to purchase a physical SIM card.

Data eSIMs are also becoming increasingly popular for IoT devices, such as smartwatches, fitness trackers, and smart home devices, which require data connectivity to function properly. Data eSIMs provide a more convenient and cost-effective way to connect these devices to mobile networks.
