Difference between a SIM and eSIM
What is an eSim?
An eSIM is a virtual SIM card that securely stores data and connects to networks. Its digital nature allows online activation without physical cards. Supports dual phone numbers on one device—perfect for separating work/personal use or travel.
eSIMs represent mobile connectivity's future. iPhone 15, Samsung Galaxy X20, and Google Pixel 3+ support eSIMs, with some offering dual functionality. Verify compatibility on unlocked phones.
How does an eSIM work?
An eSIM works like a physical SIM but in digital format. Stack Mobile sends configuration remotely via QR code or app, connecting you to the nation's largest network. Once downloaded, it manages your connection and services just like traditional SIMs.
Unlike physical cards requiring manual swapping, eSIMs offer greater flexibility and faster activation.
Is my device eSIM compatible?
If you have an unlocked phone, it is easy to check for eSIM compatibility.

On iOS devices: Go to Settings > Cellular > Add Cellular Plan. If you see this option, your phone supports eSIM.
On Android: Go to Settings > Connections > SIM card manager. If there's an option to add a mobile plan, your device likely supports eSIM.
What type of mobile phones support an eSIM?
