Chongqing Telecom recently released a new encryption secure mobile calling service. The new service encrypts users' voice and text communications, ensuring that the content will not be susceptible to eavesdropping. Chongqing Telecom predicts that the majority of users who will subscribe to the service will belong to the local business community.
In a live demonstration, Chongqing Telecom staff showed that once a call has been connected, both callers will see an "encrypt" button. If both parties press "encrypt," the call will continue encrypted. SMS encryption operates the same way. Chongqing Telecom said that even with specialized hacker software, eavesdropping would be quite difficult.
Users, however, must have handsets that support encryption. According to Chongqing Telecom, as the service has only just been introduced, it is currently supported by just several handsets, including models from Huawei, Hisense, and China Wireless Technologies (2369.HK) subsidiary Yulong (Coolpad), but more models are expected to reach the market.
The service costs RMB 100 per month.
