Intelligent Connectivity MeSIM
img
Currently, mobile phone users often need to move across regions, the high cost of changing SIM cards and unstable network signals reduce the connectivity experience. IoT devices cannot determine the deployment location before leaving the factory, nor can they determine the local network quality. To address this, Watchdata has launched the MeSIM product, which provides one card with multiple numbers for mobile phone users and the "always online" solution for IoT devices.

The Intelligent Connectivity MeSIM product supports one card with multiple numbers. Different numbers can be intelligently switched based on established switching strategies to assist users in selecting high-quality network connections. For IoT devices, the product can bind devices with cards to prevent illegal use of the card. At the same time, when all number switches cannot be successfully registered to the network, the product automatically switches to the seed number to ensure that the device is "always online".

The production and use of SIM cards may involve issues such as resource waste, energy consumption, and environmental pollution.

The Eco SIM card is made of recyclable PVC, with raw materials mainly from waste in medical, electronic, toy, and other industries. It uses physical or chemical preparation methods and can reduce approximately 44% of carbon dioxide emissions compared to traditional PVC cards, greatly reducing the environmental pollution caused by traditional PVC materials. The raw materials have obtained GRS (Global Recycled Standard) certification.

The production and use of SIM cards may involve issues such as resource waste, energy consumption, and environmental pollution.

Compared with standard cards (ID-1), we have reduced the card base size to reduce the use of raw materials, and introduced half size SIM (1/2), quarter size SIM(1/4), and extreme-small SIM(1/10) products. Among them, the extreme-small SIM process has an invention patent.
