What is eSIM?
Η eSIM is an embedded SIM that is built directly into a device's motherboard. This means it does not require a physical card to operate, but can be programmed remotely through a mobile phone provider.
In contrast to traditional SIMs, which require physical insertion and removal, eSIM operates digitally, allowing greater flexibility and convenience for users.
📌 The 7 Main Advantages of eSIMs
1️⃣ Ease of Changing Provider Without a Physical Card
With eSIMs, users can change mobile providers without having to visit a store or receive a new physical SIM card. The change is done remotely, through a simple download of a eSIM profile from the new provider.
2️⃣ Multiple Providers & Numbers Support
eSIMs allow users to have multiple profiles from different providers on the same device. This is especially useful for travelers or people who use different numbers for personal and professional use.
3️⃣ Smaller Size & More Space for Other Components
Without the need for a physical SIM slot, manufacturers can make better use of the space inside the device. This can lead to thinner smartphones, larger batteries or even in new innovations in mobile phone design.
4️⃣ Improved Security & Harder SIM Theft
Traditional SIMs can be removed and used in another device, making them vulnerable to SIM swap scams. In contrast, an eSIM is built into the device and cannot be physically removed, which increases data security and reduces the risk of identity theft.
5️⃣ Ideal for Wearables & IoT Devices
Many devices such as smartwatches, tablets and IoT (Internet of Things) gadgets do not have enough space for a physical SIM. eSIM allows these devices to seamlessly connect to the internet, without the need for external SIM slots.
6️⃣ Easy International Usage & Roaming
Travelers can switch providers locally without buying new SIM cardsMany mobile networks offer eSIM plans specifically designed for international roaming, allowing more economical and flexible options.
7️⃣ More environmentally friendly
Traditional SIMs are made of plastic and come with packaging, creating environmental footprintIn contrast, eSIMs eliminate the need for physical production and transportation of SIM, contributing to reducing plastic waste.
