Urgent - PLS8-X modules going down with US 3G Shutdown | Telit Cinterion IoT Developer Community

June 16, 2022 - 2:17am, 457 views

Hi there,

We have a few hundred devices operating in the US on the AT&T network.

The module in use is the PLS8-X with firmware version 3.017

Our pre-research suggested that since this is a data-only module, we should not be affected by the 3G shutdown, but we are seeing more devices not connecting every day. 

We do have AT command access to the module.

Are there any diagnostics we can do to try and determine the cause of the problem ? Is there a way to confirm/configure that we are indeed trying to do a data centric connection. 

I am reading through the AT commands, but any guidance would be greatly appreciated.
