Want to know more about eSIM? Then you're in the right place. This Q&A page uncovers six pivotal aspects of the eSIM ecosystem.

Key points about eSIM technology, size, benefits, device compatibility, integration with 5G, and eSIM carriers. 

1. What is eSIM? What's the difference between SIM and eSIM? 
   An eSIM is a digital SIM integrated into devices, downloadable and programmable for network access. Unlike traditional SIM cards, it doesn't need to be physically swapped between devices and provides seamless connectivity. 
2. What is the size of an eSIM card? 
   eSIMs are very tiny, measuring 2.5 mm by 2.3 mm, much smaller compared to regular, micro, and nano SIM cards. This size allows for more compact and robust device designs. 
3. What are the eSIM advantages? 
   eSIMs simplify user onboarding, reduce logistics and support costs for providers, and enable new designs and business opportunities for device makers. They can easily switch networks and do not require physical swapping. 
4. Which smartphones support eSIM, other than the iPhone? 
   Many smartphones, tablets, and wearables support eSIM, including models from Samsung, Google, Motorola, Huawei, Oppo, and more. Major OS like Android and iOS drive the momentum for eSIM adoption. 
5. eSIM and 5G 
   Both 5G and eSIM are rapidly adopted. They support advanced IoT applications and provide enhanced connectivity for many devices. Combined, they enable innovative services not previously possible. 
6. eSIM carriers 
   Nearly 400 mobile operators support eSIM as of mid-2023. This widespread acceptance ensures broad compatibility and robust connectivity solutions, making it a preferred choice for modern mobile networks.
