BGS2T cannot connect to gateway | Thales IoT Developer Community

November 22, 2017 - 11:16am, 1872 views

Hi all,

I am trying to connect to a remote gateway (a WTX16.GSM ***) with our BGS2T.

The modem can receive and make voice calls (tested with PuTTY), but when I dial the gateway number I always get a "no carrier" response. The associated error is +CEER: 8,21,0

As far as I can tell, the operator has activated data calls on the SIM.

I am sure the gateway is properly configured and can send data, therefore the problem must be on my side.

The following is the result of AT&V command

Any help or suggestion would be really appreciated.
