Questions and Answers on Telecom 4g and CDMA

• Can telecom 4g card be used on cdma sms cat

  It depends on the model of the chip of the CDMA SMS Cat. It should be noted that the authentication mode of the telecom 4G card is completely different from that of 3G, so it cannot be used on many telecom 3G mobile phones. There are few telecom 3G mobile phones compatible with 4G cards. Therefore, it is not recommended to use 4G cards on CDMA SMS cats.
