Eco SIM

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.

Reduce carbon emissions

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.
