What is eSIM technology and how does it work?
eSIM technology, or embedded SIM, is a small rewritable SIM card that is embedded directly into a device, such as a smartwatch or smartphone. Unlike traditional SIM cards, eSIMs do not require a physical swap to change carriers or plans. Instead, users can simply download and install a new profile from their carrier, which is then stored on the eSIM. This allows for greater flexibility and convenience, as users can easily switch between different carriers or plans without having to physically replace the SIM card.
The eSIM works by storing multiple profiles, each corresponding to a different carrier or plan. When a user wants to switch to a different carrier or plan, they simply select the new profile from their device’s settings, and the eSIM will automatically connect to the new network. This process is typically seamless and does not require any physical intervention. eSIM technology is becoming increasingly popular, particularly in the wearable device market, where it allows for greater independence from smartphones.
Why does my watch have a separate phone number if it uses eSIM technology?
When you set up your watch with eSIM technology, it is assigned a separate phone number, which is used to identify the device on the cellular network. This separate phone number is necessary because the watch is essentially a separate device from your smartphone, and it needs its own unique identifier to communicate with the cellular network. Even though the watch is connected to your smartphone, it still needs its own phone number to make and receive calls, send texts, and access data.
The separate phone number is also used for billing purposes, as the watch’s data usage is typically billed separately from your smartphone’s data usage. This allows carriers to track and bill for the watch’s data usage accurately, even if it is connected to your smartphone. In some cases, the separate phone number may also be used for emergency services, such as 911 calls, to ensure that the watch can be located and identified in case of an emergency.
