Call Quality: GSM offers high-quality voice calls, making it a popular choice for mobile phones.

In summary, GSM is a widely used mobile telecommunications technology known for its high-quality voice calls, secure communications, and support for SMS and MMS. It uses circuit-switched technology, supports dual-band and tri-band frequencies, provides secure communications, and supports SMS and MMS. Can provide mobile coverage in a variety of environments, GSM is known for its high-quality voice calls and global roaming capabilities.

The GSM module is a functional module that integrates GSM radio frequency chips, baseband processing chips, memory, power amplifiers, etc. on the circuit board. It has an independent operating system, GSM radio frequency processing, baseband processing, and provides standard interfaces.
