Friends who often use electronic products or have more contact with related personnel must be very familiar with the two concepts of GSM and CDMA. Our article has also explained the difference between GSM and CDMA many times. Today I will take you to summarize and sort out the differences between the two from another angle.

Since the birth of mobile phone technology, the main difference between GSM and CDMA is the use of SIM cards. Under GSM, users can take out the SIM card and put it in a new phone. At the same time, if users want to change their phones, they must abide by the terms and conditions of their CDMA operators.

SIM card use
The use of SIM cards is the main difference between GSM and CDMA. Under GSM, users can take out the SIM card and put it in a new phone. On the other hand, if CDMA wireless phones want to change their phones, they must abide by the terms and conditions and call their CDMA operators.

Conversation quality
The call quality of these two national networks depends to a large extent on the network coverage. In certain areas, GSM desk phone users can experience better voice quality than CDMA users, and vice versa. In addition, the GSM network can transmit voice and data at the same time. On the other hand, not all CDMA cell phones can transmit voice and data at the same time. In addition to network congestion, CDMA call quality is often better than GSM wireless phones.

Network coverage
GSM uses ore dedicated network tower plus it supports global roaming. On the contrary, the CDMA network tower is wider and covers a larger area, but only has limited roaming options. Today, most users in the world are using GSM, but half of the population in the United States, Canada, and Japan still use CDMA.
