SIM Card
  A SIM card is a smart card inside a cellular phone that encrypts voice and data transmissions and stores data about the specific user so that the user can be identified and authenticated to the network supplying the phone service. SIM cards help prevent wiretapping, giving users access to more secure and reliable telecom services.
 

In 2003, Hua Hong Group’s high security microcontroller chip was honored as the first certified EAL4+ chip in China.

So far Hua Hong Group has developed a variety of chips which support 16K, 32K, 64K, 128K, 256K, and 3G GSM SIM cards. The chips also support value-added telecom services such as Color Ring Back Tone (CRBT), mobile email, and mobile payment. Hua Hong Group has become one of major SIM card suppliers for leading telecom operators in China, including China Mobile, China Unicom, and China Telecom. Now the overseas market emerges as the next target for Hua Hong Group’s SIM products which have already secured successes in India, Nepal, Iran, Turkey, Vietnam, and Benin.
