How to Judge Whether the EC321 Data Card Has Been Installed
Correctly?
After installing the EC321 Data Card, two devices are displayed in the device manager,
namely, the "HUAWEI Mobile Connect-3G Modem" and the "HUAWEI Mobile
Conncet-3G Application Interface".
Check whether these two devices are installed correctly at first. If a yellow exclamatory
mark or other signs appear in front of the devices, it means that the data card has not been
installed correctly, and you need to retry.
After Installing the EC321 Management Software, the System
Always Prompts "Data Card does not Exist". Why?
Probably you have inserted the data card before the completion of installing the EC321
management software. Pull out the data card and insert it after the installation of EC321
management software is completed. Then, install the EC321 hardware driver by
following the guide for the hardware installation.
After Installing the EC321 Management Software, the System
Always Prompts "Unidentified USB device". Why?
If the prompt "Unidentified USB device" displays on the task bar, your data card still can
be used.
What Shall I Do If I Cannot Access the Internet?
1. Check whether you have activated the wireless online service at first. Ask the local
network operator for how to activate it.
2. If you are sure that the wireless online service has been activated, refer to "Internet
Service" to implement relevant settings.
Only Part of the Message Is Displayed After I Use the "Paste"
Function to Edit It. Why?
While editing the message, at most 1000 characters are supported in the text. If the
quantity of the pasted information exceeds the limitation, the exceeded part will be
deleted automatically.
When a Message Is Received, No Prompt Displays. Why?
Because you have not set the SMS Alerts function.
