Verifying that the Yeastar TG200 has LTE radios

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. 
Notes
Note:  TopView 7.4 and later include a utility to verify LTE radios. This utility requires that SSH is enabled in the TG200 (first step below).
TopView Configurator: Tools > Support apps > Yeastar TG200 LTE Check

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]

Notes
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.
