An eSIM, or Embedded SIM, is a digital version of a physical SIM card that allows users to activate a cellular plan without a physical chip. eSIMs are built into newer smartphones and can be programmed remotely.

Here are some benefits of eSIMs: 

• Flexibility: Users can add plans, a new number, or connect to a different carrier. 
• Convenience: Users can have multiple lines on the same device. 
• International travel: Users can easily add an international plan. 
• Space savings: The absence of a physical SIM card slot frees up space for other upgrades. 
• Security: eSIMs provide an additional layer of security. 
• Sustainability: eSIMs reduce the need for users to own multiple plastic SIM cards.

Some drawbacks of eSIMs include:

• Not all devices support eSIMs.
• The activation process can be more complex than inserting a physical SIM card.
• Moving an eSIM to a different device involves more steps than swapping a physical SIM card.

To activate an eSIM, users can contact NEO Business Wireless to get a QR code, then scan the code with their phone's settings menu.
