Application Guide

13.1 Voice Calls and Text Messaging

On a GSM or WCDMA network, the module uses the same wireless channel to

establish voice calls and send text messages. Therefore, when the module provides

voice call and text messaging services at the same time, it may fail to make the voice

call or the message may be delayed.
