SMS-module do not send SMSs

[chema61]

Hi: since a month or so my SMS module do not respond to the calls for SMS and do not send send test SMS.

I have checked everything I may think of. The SIM card is active (checked in a phone) and do not require pin. All the lights in the module indicate status OK. Firmware version is 3,04.

I would appreciate any clue what may be wrong. Thanks

Hello,

the SMS module only supports GSM networks (2G), your operator has probably switched off this network.

I have been informed by my company that they have disconnected the 3G network, not the 2G. Actually, I'm receiving SMS from a variety of senders.

Solved. It was a problem with one of the settings, most likely changed during the last firmware update of the Profilux.

Thanks for the feedback.
What parameter has been changed?
