: Experience On-Chain Interaction with the World’s First Blockchain SIM Card!

• Conflux Network and China Telecom have debuted a Blockchain SIM card.
• The BSIM card is fully compatible with Android and iOS devices.
• It has the ability to generate and store users’ public and private keys in a secure manner.


Chainwire Conflux Network, the first regulatory compliant public blockchain in China, and global communications network, China Telecom, today unveiled their jointly developed Blockchain SIM (BSIM) card at the Xuhui District West Bank Artificial Intelligence Center in Shanghai.

Features of the BSIM Card

The BSIM card is nearly identical to traditional SIM cards but with larger storage space (10-20x) and greater computing power (several dozen times). On top of traditional communications functions, it can also generate and store users’ public and private keys within the card securely. This reduces the risk of mobile terminals being attacked by malware or virus software. It also offers encrypted storage, key recovery functions, as well as U-shield features for added security.

First On-Chain Interaction

At the launch event, Dr Wu Ming from Conflux successfully transferred a Commemorative NFT of the China Telecom and Conflux Partnership from one BSIM account to another using an app on his phone. This marked the first on-chain, public use of the BSIM card.

Dr Wu Ming’s Statement

Dr Wu Ming stated that this new technology will provide more secure digital identity access for mobile communication users while eliminating technical barriers to Web3 applications and metaverse access for all users.


Li Anmin from China Telecom Group commented that both companies are dedicated to developing practical communication technologies that incorporates blockchain technology into people’s daily lives through extensive research and promotion activities.
