4G Router send and receive SMS gateway on SSH Shell

Send and Receive SMS on 4G Router SSH Shell

The EZRx3 series 4G routers use QMI protocol by default to establish a 4G connection to the mobile networks. We can use UQMI commands to send and receive an SMS text message on the SSH shell.

1) Please log in to the SSH command-line interface. How to access SSH?

2) Use below UQMI commands to access and control the SMS gateway.

UQMI Command Function
List SMS messages
--get-message <id>:
Get SMS raw message contents at index <id>
--send-message <data>:
Send SMS message (use options below)
--send-message-smsc <nr>:
SMSC number (required)
--send-message-target <nr>:
Destination number (required)
Send as Flash SMS



3) Examples
The virtual modem interface is /cdc-wdm0. So the command always starts with uqmi -d /dev/cdc-wdm0.

i. If need to list the received SMS message, on SSH terminal use the command:

uqmi -d /dev/cdc-wdm0 --list-messages 

ii. Use the below command to read one of the messages, for example, read No.2 message.

uqmi -d /dev/cdc-wdm0 --get-message 2

iii. When sending an SMS message, we need to attach the target phone number. Below is an example of sending a message of “Testing” to target mobile phone number “2001111“. Make sure without country code, space, and symbols on the phone number.

uqmi -d /dev/cdc-wdm0 --send-message Testing --send-message-target 2001111

Please ensure your SIM card supports the SMS function. Some of the data-plan SIM cards do not support the SMS function.
