1, What’s eSIM and vSIM card?
eSIM card, i.e. Embedded-SIM, embedded SIM card. eSIM card concept is the traditional SIM card directly embedded in the device chip, rather than as an independent removable part to join the device, the user does not need to insert a physical SIM card set to save more design space, can allow manufacturers to have more room to play, to provide consumers with a better consumer experience. eSIM can almost be considered as a tailor-made technology for IoT, eSIM is just one type of virtual SIM technology
vSIM, using advanced VSIM technology can realize cardless roaming business model on cell phone terminals, so it is widely used in the field of international roaming. vSIM covers more than 100 countries, in addition, the whole cost and traffic price of vSIM is much cheaper. vSIM technology is currently mainly represented by roaming treasure, Global Roaming and other roaming solution providers.
2, What innovative application scenarios can IoT SIM cards be used in?
It’s suitable for long-distance communication, and the transmission rate of a higher requirements of the scene.
For example: location tracking: GPS+LBS coverage indoor positioning outdoor data transmission. Remote intelligent meter reading and timed automatic data reporting.
Wireless mobile POS: to realize portable and wide network coverage. Vehicle networking: vehicle positioning, large data transmission (remote diagnosis, remote maintenance).
Video transmission: real-time video monitoring, video conferencing. Wearable devices: smart watches, bracelets. Positioning data transmission is possible.
Medical industry: 4G, 5G, NB-IOT technology is applied to the medical industry and integrated into a service platform to realize remote diagnosis, patient self-service query, call center, and smart medical services between hospitals and patients, doctors and patients, and family members and patients.
Smart city construction: the most common smart street light scenarios can utilize IOT sim card for data transmission with low power and low latency. City brain rational planning traffic lights, intelligent well cover transformation.
3, How can eSIM and vSIM help enterprises reduce costs?
- Long service life, eSIM service life is 15 years, while vSIM service life does not have any limitation. Therefore, it greatly reduces the cost for enterprises.
- Cheap tariffs and low operating costs. eSIM/vSIM’s ability to write cards over the air is a perfect solution to the problem of mobile tariffs for devices in the global market. Before the device reaches each new region, it only needs to update the configuration with internet connection, and then it can be used to access the internet with local tariffs after arriving at the new region. There is no need to re-apply for a new card, which reduces the cost of operation.
- Small size and low cost. eSIM embeds the SIM card directly into the device, and its size is several times smaller than Nano. vSIM does not have the traditional card body, and it directly relies on the communication module to realize the communication, which greatly saves the cost of hardware. Convenient for enterprises to mass produce.
4, What is the biggest change brought by IoT SIM card for consumers?
- Lower Cost With the elimination of the need for a separate SIM card slot, future eSIM-designed devices will be lighter and thinner, and consumers will be able to switch carriers at any time due to cost and carrier advantages. For those who have multiple cell phone numbers, the eSIM card design is more attractive, because they no longer need multiple cell phones to switch, enterprise users can also greatly reduce the cost of their own equipment purchase.
- Ease of Use Traditional billing methods and long-term contracts have begun to disappear from the market as consumers can switch carriers more easily.
- High Security Since cell phones no longer require a physical SIM card, hacking stolen phones has become unnecessary in the future.
