What are the differences between CDMA and GSM?

Answer 1

• CDMA:
  
  • Tied to the carrier, meaning phones are often locked to a specific network.

  • Uses code division to allow multiple users to share the same frequency band.
  • More efficient in terms of bandwidth usage.
• GSM:
  
  • More widely adopted globally.
  • Example: AT&T and T-Mobile in the U.S.
