Verifying that the Yeastar TG200 has LTE radios

The Yeastar TG200 has 2 cellular radios. These cellular radios can be activated by inserting a SIM card into either of the 2 SIM slots on the front of the device.
Older TG200 models are 3G and do not support newer GSM LTE SIMs (AT&T, T-Mobile, ...).  The following steps will allow you to check the model of the radios in the Yeastar to verify that they support LTE. 

Enable SSH on the TG200 device

Log into the Web interface of the TG200
System > Security center 
Check "Enable SSH", then [Save] and [Apply changes]

When you save the change, the SSH password will be displayed. The default password is iyeastar. You will need this password to log into the Yeastar via SSH.

Install an SSH client (PuTTY)

This article uses PuTTY as the SSH client. Download PuTTY

PuTTY setting (optional)

Increase the scrollback count to increase the number of lines in the terminal window


SSH Client settings:

  1. Host name: the IP address of the TG200
  2. Port: 8022 (this is the default port for SSH and is displayed on the screen where you enabled SSH)
  3. Connection type: SSH

Launch the SSH client and log in
